▶ Ruri Tanigawa : Whoa...	(0:00:02.90)
▶ Ruri Tanigawa : Wow! This place is huge!	(0:00:05.82)
▶ Nagi Arato : Ruri! This way.	(0:00:08.93)
▶ Ruri Tanigawa : What's with this place?	(0:00:24.50)
▶ Ruri Tanigawa : What's this?	(0:01:58.59)
▶ Nagi Arato : It's my paper on pyrite.	(0:01:59.93)
▶ Nagi Arato : This is why I brought you to my university.	(0:02:02.49)
▶ Ruri Tanigawa : You expect me to understand this?	(0:02:06.98)
▶ Ruri Tanigawa : That's my name!	(0:02:09.90)
▶ Nagi Arato : Remember when we collected pyrite together?	(0:02:11.68)
▶ Ruri Tanigawa : When I found that rare form of pyrite?	(0:02:13.94)
▶ Nagi Arato : Like I thought, there weren't any existing reports on it.	(0:02:16.86)
▶ Nagi Arato : So I couldn't help myself.	(0:02:20.20)
▶ Ruri Tanigawa : B-But I didn't do anything.	(0:02:23.12)
▶ Nagi Arato : It's a paper on the specimen you found.	(0:02:25.81)
▶ Nagi Arato : Of course your name is on it.	(0:02:28.12)
▶ Nagi Arato : With every new discovery, it's important to	(0:02:30.21)
▶ Nagi Arato : record that information and make it known to the public.	(0:02:32.10)
▶ Nagi Arato : You never know when personal records could get lost.	(0:02:36.18)
▶ Nagi Arato : I'm relieved that I could publish it.	(0:02:39.85)
▶ Ruri Tanigawa : Nagi-san...	(0:02:42.45)
▶ Ruri Tanigawa : This makes me so happy!	(0:02:45.02)
▶ Ruri Tanigawa : I never imagined my little discovery could be so meaningful!	(0:02:47.20)
▶ Nagi Arato : Yeah? I'm glad to hear that.	(0:02:51.32)
▶ Ruri Tanigawa : You really are amazing, Nagi-san.	(0:02:54.22)
▶ Ruri Tanigawa : You've studied so much.	(0:02:56.80)
▶ Ruri Tanigawa : I mean, you're a graduate student.	(0:02:59.16)
▶ Ruri Tanigawa : Obviously, you're way out of my league.	(0:03:01.29)
▶ Ruri Tanigawa : Look at all those difficult books...	(0:03:05.37)
▶ Ruri Tanigawa : And collected specimens...	(0:03:07.83)
▶ Ruri Tanigawa : And scraps of paper...?	(0:03:09.24)
▶ Ruri Tanigawa : And expired snacks?	(0:03:11.61)
▶ Ruri Tanigawa : A-Actually, it's kinda messy in here.	(0:03:16.30)
▶ Nagi Arato : Yeah, just a bit.	(0:03:19.06)
▶ Nagi Arato : I should probably tidy up sometime.	(0:03:21.11)
▶ Youko Imari : Arato-senpai!	(0:03:24.55)
▶ Youko Imari : Did I just hear you say, ＂tidy up?＂	(0:03:26.14)
▶ Youko Imari : Phew, thanks.	(0:03:32.53)
▶ Youko Imari : Huh?	(0:03:34.89)
▶ Youko Imari : Would you happen to be Ruri-chan?!	(0:03:37.29)
▶ Youko Imari : The girl who found that pyrite?!	(0:03:39.37)
▶ Ruri Tanigawa : Uh, yeah... and you are?	(0:03:41.70)
▶ Youko Imari : Oh, I'm a senior undergrad from the same research group as Arato-senpai.	(0:03:45.55)
▶ Youko Imari : My name is Imari Yoko. Nice to meet you.	(0:03:49.78)
▶ Ruri Tanigawa : Oh, nice to meet you, too.	(0:03:52.24)
▶ Nagi Arato : Tending to books again?	(0:03:54.24)
▶ Youko Imari : I was just outside airing these out.	(0:03:55.83)
▶ Youko Imari : So? Are you finally willing to do some cleaning?	(0:03:59.44)
▶ Youko Imari : Books deserve better than dust and mold, you know.	(0:04:03.04)
▶ Nagi Arato : H-Hold on, I didn't mean right this minute.	(0:04:05.23)
▶ Nagi Arato : You know, maybe when I get the right nudge.	(0:04:09.12)
▶ Ruri Tanigawa : Oh boy...	(0:04:17.70)
▶ Ruri Tanigawa : Nagi-san! This is a crystal, right?	(0:04:25.65)
▶ Nagi Arato : Yup, sure is.	(0:04:28.32)
▶ Nagi Arato : It's yours, if you want.	(0:04:34.75)
▶ Ruri Tanigawa : Yay!	(0:04:36.52)
▶ Youko Imari : Might as well clean now, don't you think?	(0:04:38.05)
▶ Nagi Arato : Umm, actually...	(0:04:41.04)
▶ Nagi Arato : I should take Ruri home, so maybe another time.	(0:04:43.34)
▶ Ruri Tanigawa : I don't mind cleaning right now!	(0:04:48.86)
▶ Ruri Tanigawa : If you'll let me look for treasure, that is!	(0:04:51.10)
▶ Ruri Tanigawa : Question!	(0:04:56.19)
▶ Ruri Tanigawa : So any rock on the floor is up for grabs?	(0:04:57.19)
▶ Nagi Arato : Yup.	(0:04:59.71)
▶ Youko Imari : Nice!	(0:05:00.37)
▶ Ruri Tanigawa : All righty then!	(0:05:01.06)
▶ Ruri Tanigawa : Time to clean!	(0:05:02.02)
▶ Ruri Tanigawa : This is... just an ordinary rock.	(0:05:06.71)
▶ Ruri Tanigawa : How about...	(0:05:15.63)
▶ Ruri Tanigawa : This?!	(0:05:18.14)
▶ Ruri Tanigawa : What the heck?!	(0:05:19.55)
▶ Ruri Tanigawa : Look!	(0:05:21.84)
▶ Ruri Tanigawa : It's like, alien-shaped!	(0:05:23.09)
▶ Ruri Tanigawa : No way this is from Earth!	(0:05:25.51)
▶ Nagi Arato : That's bismuth.	(0:05:28.32)
▶ Ruri Tanigawa : Bismoot?	(0:05:29.39)
▶ Nagi Arato : Bismuth, a metallic element.	(0:05:31.14)
▶ Nagi Arato : This one's been artificially crystallized.	(0:05:33.24)
▶ Ruri Tanigawa : Artificial?!	(0:05:37.00)
▶ Ruri Tanigawa : No way! Humans can't make this .	(0:05:38.04)
▶ Nagi Arato : Fine, then let me show you.	(0:05:40.89)
▶ Ruri Tanigawa : You can make it?	(0:05:46.90)
▶ Nagi Arato : Yup. All we need is this bismuth crystal.	(0:05:48.14)
▶ Nagi Arato : This will take a while.	(0:05:51.87)
▶ Ruri Tanigawa : Weird, I thought it would smell more.	(0:05:54.82)
▶ Ruri Tanigawa : Whoa! It's starting to melt!	(0:05:57.40)
▶ Nagi Arato : Once it's fully melted, turn off the heat.	(0:05:59.56)
▶ Nagi Arato : And remove the oxide film from the surface.	(0:06:03.03)
▶ Nagi Arato : After that, gently insert a wire into the center.	(0:06:08.38)
▶ Nagi Arato : Then allow it to cool, and voilà.	(0:06:12.57)
▶ Ruri Tanigawa : That's it?	(0:06:15.34)
▶ Nagi Arato : Yup.	(0:06:16.92)
▶ Nagi Arato : Molten bismuth cools, forming a crystal.	(0:06:18.57)
▶ Nagi Arato : As it changes from liquid to solid, the crystal releases latent heat.	(0:06:22.35)
▶ Nagi Arato : This causes a difference in temperature.	(0:06:28.39)
▶ Nagi Arato : Areas with cooler temperatures solidify faster,	(0:06:30.93)
▶ Nagi Arato : which forms hopper crystals with edges and hollows.	(0:06:34.99)
▶ Nagi Arato : The only trick is to remove the crystal before it fully cools.	(0:06:38.85)
▶ Nagi Arato : It's that simple. Anyone can do it.	(0:06:42.02)
▶ Nagi Arato : See?	(0:06:45.24)
▶ Ruri Tanigawa : It's so pretty!	(0:06:46.42)
▶ Nagi Arato : Another point is to cool it slowly.	(0:06:47.29)
▶ Youko Imari : Arato-senpai!	(0:06:49.89)
▶ Youko Imari : You haven't forgotten about the task at hand, right?	(0:06:52.18)
▶ Ruri Tanigawa : You've got so many books.	(0:07:06.42)
▶ Youko Imari : Think so?	(0:07:08.37)
▶ Youko Imari : You're too nice!	(0:07:10.80)
▶ Ruri Tanigawa : You took that as a compliment?	(0:07:12.06)
▶ Youko Imari : They're all rare books out of print.	(0:07:14.04)
▶ Youko Imari : Why'd you want old books?	(0:07:17.96)
▶ Youko Imari : Did you know? Information from the past can get lost if not preserved.	(0:07:20.13)
▶ Youko Imari : Not to mention, specialized books back then had few copies.	(0:07:24.62)
▶ Youko Imari : That said, geological surveys rarely get updates.	(0:07:27.80)
▶ Youko Imari : So compared to other fields, a lot of old findings still hold true today.	(0:07:31.23)
▶ Youko Imari : Which means it's our duty to preserve old books!	(0:07:35.21)
▶ Nagi Arato : In other words, even dated information holds some value.	(0:07:38.48)
▶ Youko Imari : Not true!	(0:07:42.86)
▶ Youko Imari : Information from the past is much, much more valuable!	(0:07:44.56)
▶ Youko Imari : Arato-senpai, you don't get it at all.	(0:07:47.36)
▶ Ruri Tanigawa : Prolly trash.	(0:07:57.34)
▶ Youko Imari : It's an old topographic map!	(0:08:03.08)
▶ Ruri Tanigawa : I-I found it underneath the desk!	(0:08:05.33)
▶ Nagi Arato : When's it from?	(0:08:07.58)
▶ Youko Imari : Let's see...	(0:08:08.69)
▶ Youko Imari : This mine is still running, so I'm guessing early Showa Era.	(0:08:09.86)
▶ Nagi Arato : That's when they overexploited mines pursuing mineral self-sufficiency.	(0:08:13.93)
▶ Nagi Arato : A rare find.	(0:08:17.39)
▶ Ruri Tanigawa : Hey, hey. What's so great about it?	(0:08:19.60)
▶ Ruri Tanigawa : What's it good for?	(0:08:21.48)
▶ Youko Imari : You see, it's a treasure map!	(0:08:22.48)
▶ Ruri Tanigawa : A map of... treasures?!	(0:08:26.38)
▶ Ruri Tanigawa : I love that kind of stuff!	(0:08:30.71)
▶ Ruri Tanigawa : Tell me more!	(0:08:32.25)
▶ Youko Imari : Sure thing.	(0:08:33.47)
▶ Ruri Tanigawa : Not like that!	(0:08:34.95)
▶ Ruri Tanigawa : I meant a quick rundown!	(0:08:35.93)
▶ Youko Imari : These two maps are from different eras.	(0:08:38.71)
▶ Youko Imari : But look.	(0:08:42.21)
▶ Youko Imari : The old map includes a mine symbol.	(0:08:43.04)
▶ Youko Imari : Compare that to the recent map.	(0:08:46.40)
▶ Ruri Tanigawa : Huh? This one doesn't have a symbol.	(0:08:49.05)
▶ Youko Imari : So what happened to it?	(0:08:51.26)
▶ Youko Imari : The answer lies... in this third map!	(0:08:52.75)
▶ Youko Imari : See? The mine was shut down.	(0:08:56.47)
▶ Youko Imari : Operating mines are shown on maps with the mine symbol,	(0:08:59.72)
▶ Youko Imari : along with its main ore, like this.	(0:09:02.61)
▶ Youko Imari : But that changes once mining ends.	(0:09:05.51)
▶ Youko Imari : And when the mine is demolished or abandoned, it's wiped completely.	(0:09:08.75)
▶ Ruri Tanigawa : Won't that make it impossible to find?	(0:09:12.49)
▶ Youko Imari : It sure does.	(0:09:15.50)
▶ Youko Imari : But for closed mines to be displayed on maps,	(0:09:16.40)
▶ Youko Imari : the rule requires a landmark, like a smokestack.	(0:09:18.59)
▶ Youko Imari : Once removed, it's up to our own research.	(0:09:22.30)
▶ Youko Imari : In the end, modern information alone won't cut it.	(0:09:25.30)
▶ Youko Imari : Unless you've gathered old records like me, that is.	(0:09:29.81)
▶ Ruri Tanigawa : But the mine closed, right?	(0:09:33.52)
▶ Ruri Tanigawa : Wouldn't it be out of minerals?	(0:09:35.70)
▶ Youko Imari : They'd be out of money if they dug that long.	(0:09:37.64)
▶ Youko Imari : Most mines close before they exhaust resources.	(0:09:40.94)
▶ Youko Imari : I bet there's some minerals still there.	(0:09:43.07)
▶ Youko Imari : See? I told you it was a treasure map!	(0:09:45.65)
▶ Ruri Tanigawa : An old mine, huh? Sounds pretty cool.	(0:09:48.37)
▶ Nagi Arato : Wanna try finding one, Ruri?	(0:09:51.75)
▶ Nagi Arato : Take your pick.	(0:09:53.97)
▶ Ruri Tanigawa : You mean it?!	(0:09:54.97)
▶ Youko Imari : You should pick somewhere accessible.	(0:09:56.03)
▶ Youko Imari : Somewhere close to main roads with preserved paths.	(0:09:58.05)
▶ Ruri Tanigawa : I wanna go here!	(0:10:02.58)
▶ Youko Imari : There?	(0:10:04.29)
▶ Youko Imari : Why somewhere that deep of all places?	(0:10:05.61)
▶ Youko Imari : Sure, it doesn't include its main ore, but—	(0:10:08.39)
▶ Ruri Tanigawa : It's gotta be this one!	(0:10:10.50)
▶ Ruri Tanigawa : The map doesn't even know about this mystery mine!	(0:10:12.60)
▶ Ruri Tanigawa : It smells the most like treasure!	(0:10:14.95)
▶ Youko Imari : Can't say I recommend it.	(0:10:18.98)
▶ Youko Imari : It's best to avoid places with uncertain information.	(0:10:21.15)
▶ Youko Imari : Safety is always the highest priority.	(0:10:23.87)
▶ Nagi Arato : Yeah, but that information can be confirmed on site.	(0:10:26.77)
▶ Nagi Arato : As for safety, I'll make that call when we get there.	(0:10:30.82)
▶ Ruri Tanigawa : And I bet we have a better chance of finding cool minerals where there's less people!	(0:10:35.37)
▶ Youko Imari : Who knows if that's true?	(0:10:40.08)
▶ Youko Imari : We could be completely off the mark.	(0:10:41.72)
▶ Ruri Tanigawa : It'll be fine.	(0:10:44.17)
▶ Ruri Tanigawa : I don't know what'll be there,	(0:10:45.69)
▶ Ruri Tanigawa : but there's gotta be something , right?	(0:10:47.38)
▶ Youko Imari : I mean, sure, but...	(0:10:50.13)
▶ Nagi Arato : You should come with us, Imari.	(0:10:52.30)
▶ Nagi Arato : You've hardly been out to collect ore at all.	(0:10:54.03)
▶ Youko Imari : Really?	(0:10:56.60)
▶ Youko Imari : I'm totally happy studying books, though.	(0:10:57.96)
▶ Nagi Arato : It's not bad being the author for a change.	(0:11:02.09)
▶ Youko Imari : Hard to say no when you put it like that.	(0:11:09.16)
▶ Ruri Tanigawa : What are we waiting for? Let's go!	(0:11:13.28)
▶ Youko Imari : If that's the case, we'll have to prepare.	(0:11:13.28)
▶ Nagi Arato : Let me look over next week's plans.	(0:11:15.22)
▶ Youko Imari : We'll need all the time we can get to research beforehand.	(0:11:15.22)
▶ Youko Imari : We need to plan a schedule, look over bear occurrences,	(0:11:17.92)
▶ Youko Imari : check records on past incidents, and get survival gear just in case.	(0:11:20.02)
▶ Youko Imari : Yup! Six months should give us plenty of time to prep!	(0:11:21.68)
▶ Youko Imari : Huh?	(0:11:26.04)
▶ Youko Imari : It's not here.	(0:11:35.36)
▶ Youko Imari : There's no mine in sight.	(0:11:36.47)
▶ Ruri Tanigawa : But this is where the mine symbol points to, right?	(0:11:39.49)
▶ Ruri Tanigawa : It's gotta be here then.	(0:11:42.49)
▶ Youko Imari : That’s not much to go on.	(0:11:45.71)
▶ Nagi Arato : This ore has a different expression.	(0:11:48.03)
▶ Ruri Tanigawa : Expression?	(0:11:50.51)
▶ Ruri Tanigawa : Imari-san, what kind of rock is this?	(0:11:53.44)
▶ Youko Imari : Let me see.	(0:11:55.65)
▶ Youko Imari : This ore is...	(0:11:56.57)
▶ Youko Imari : Um, I don't know.	(0:12:00.06)
▶ Nagi Arato : They're a bit heavy.	(0:12:03.97)
▶ Nagi Arato : I'm guessing they contain...	(0:12:05.84)
▶ Ruri Tanigawa : It stuck together! What's that?	(0:12:13.75)
▶ Nagi Arato : Just an ordinary magnet.	(0:12:16.32)
▶ Nagi Arato : This ore must contain a good amount of magnetite.	(0:12:18.20)
▶ Ruri Tanigawa : Magnetite?	(0:12:21.56)
▶ Nagi Arato : A notable type of iron ore.	(0:12:23.22)
▶ Youko Imari : You know iron sand? That's just crushed magnetite!	(0:12:25.61)
▶ Youko Imari : They're pretty common, with black octahedral crystals that have a metallic luster.	(0:12:27.84)
▶ Ruri Tanigawa : Where was all that information a second ago?	(0:12:32.13)
▶ Nagi Arato : It's not rare for minerals to look different in real life.	(0:12:35.90)
▶ Nagi Arato : I get stumped all the time, too.	(0:12:39.30)
▶ Ruri Tanigawa : So our target turned out to be an iron mine?	(0:12:45.80)
▶ Ruri Tanigawa : All we can get are magnetic rocks.	(0:12:48.42)
▶ Ruri Tanigawa : I wish the map just said that.	(0:12:51.03)
▶ Youko Imari : W-Well I think this is a pretty cool ore.	(0:12:52.91)
▶ Nagi Arato : Iron mine or not, that doesn't mean iron is the only thing we'll find.	(0:12:56.09)
▶ Nagi Arato : Who knows? You might find a stone you like.	(0:13:00.71)
▶ Nagi Arato : If you ask me, this magnetite should lead us to the old mine.	(0:13:03.68)
▶ Ruri Tanigawa : You mean up this slope?	(0:13:08.33)
▶ Nagi Arato : We came all this way.	(0:13:09.80)
▶ Nagi Arato : Might as well find the old mine.	(0:13:11.56)
▶ Nagi Arato : Looks like this is it.	(0:13:23.59)
▶ Nagi Arato : This was once the backbone of Japan's industrial sector.	(0:13:25.82)
▶ Nagi Arato : Although it's pretty much returned to nature.	(0:13:28.50)
▶ Ruri Tanigawa : Wow! This is an old mine ruin?	(0:13:31.09)
▶ Youko Imari : This must be it.	(0:13:45.56)
▶ Nagi Arato : They weren't supposed to leave the entrance open like this.	(0:13:46.68)
▶ Ruri Tanigawa : Huh? Wait a second.	(0:13:49.84)
▶ Ruri Tanigawa : Isn't this super far from the mine symbol?	(0:13:52.10)
▶ Ruri Tanigawa : That map was way off!	(0:13:55.06)
▶ Nagi Arato : Not exactly.	(0:13:57.07)
▶ Nagi Arato : Take a proper shape like this.	(0:13:58.75)
▶ Nagi Arato : Where would you place a mine symbol?	(0:14:00.95)
▶ Ruri Tanigawa : In the center!	(0:14:02.78)
▶ Nagi Arato : Right.	(0:14:03.83)
▶ Nagi Arato : Now what if things were located like this?	(0:14:05.00)
▶ Nagi Arato : A map can only include so much.	(0:14:08.84)
▶ Nagi Arato : You'd be surprised at what information you can only find on site.	(0:14:11.40)
▶ Youko Imari : Makes sense.	(0:14:14.69)
▶ Nagi Arato : Hey!	(0:14:19.74)
▶ Nagi Arato : Get out of there, it's dangerous.	(0:14:20.73)
▶ Ruri Tanigawa : But we're exploring the mine, right?	(0:14:23.46)
▶ Ruri Tanigawa : What good is it if we don't go inside?	(0:14:25.47)
▶ Nagi Arato : We can search the tailings.	(0:14:27.56)
▶ Ruri Tanigawa : Tailings?	(0:14:29.35)
▶ Nagi Arato : Mines usually leave behind extracted rocks with little industrial value.	(0:14:30.49)
▶ Nagi Arato : In other words, even pretty rocks get discarded if they're not worth much economically.	(0:14:35.57)
▶ Nagi Arato : The tailings are our best shot.	(0:14:41.09)
▶ Ruri Tanigawa : Okay! Got it!	(0:14:44.04)
▶ Ruri Tanigawa : Let's search here today!	(0:14:46.13)
▶ Ruri Tanigawa : Where's my crystal?	(0:14:50.16)
▶ Ruri Tanigawa : Is it this one?	(0:14:51.96)
▶ Ruri Tanigawa : What about this one?	(0:14:53.08)
▶ Ruri Tanigawa : Or maybe this one!	(0:14:54.38)
▶ Ruri Tanigawa : How about this one?!	(0:14:55.73)
▶ Youko Imari : You've got so much energy, Ruri-chan.	(0:14:56.83)
▶ Ruri Tanigawa : Imari-san!	(0:15:00.32)
▶ Ruri Tanigawa : What's this stone?	(0:15:01.59)
▶ Ruri Tanigawa : Huh?	(0:15:04.23)
▶ Ruri Tanigawa : Imari-san?	(0:15:10.81)
▶ Ruri Tanigawa : Hey!	(0:15:15.23)
▶ Ruri Tanigawa : Imari-san...	(0:15:17.02)
▶ Ruri Tanigawa : Imari-san, you okay?	(0:15:23.98)
▶ Youko Imari : I'm not sure.	(0:15:26.78)
▶ Ruri Tanigawa : Are we inside the mine?	(0:15:29.23)
▶ Youko Imari : This portion of the roof must have caved in.	(0:15:31.04)
▶ Ruri Tanigawa : Imari-san, is this a crystal?	(0:15:37.71)
▶ Youko Imari : Can't tell.	(0:15:42.59)
▶ Ruri Tanigawa : Are you sure you study mineralogy?	(0:15:44.03)
▶ Ruri Tanigawa : Meh, doesn't have a great shape though.	(0:15:47.27)
▶ Ruri Tanigawa : Never mind.	(0:15:49.73)
▶ Nagi Arato : Hey!	(0:15:50.47)
▶ Nagi Arato : Anyone there?	(0:15:51.76)
▶ Nagi Arato : Thought I heard something.	(0:15:54.60)
▶ Youko Imari : Arato-senpai! Over here!	(0:15:55.87)
▶ Nagi Arato : Where's that?	(0:15:58.22)
▶ Ruri Tanigawa : Look down! We fell in a hole!	(0:15:59.37)
▶ Nagi Arato : A hole? I don't see anything.	(0:16:02.16)
▶ Youko Imari : We're down here!	(0:16:05.65)
▶ Nagi Arato : Oh, there you are.	(0:16:12.20)
▶ Nagi Arato : It's too weathered to climb.	(0:16:17.72)
▶ Nagi Arato : I doubt we can get out this way.	(0:16:20.26)
▶ Nagi Arato : That path should take us to the exit.	(0:16:24.12)
▶ Nagi Arato : Shouldn't be too far from here.	(0:16:26.59)
▶ Nagi Arato : We could use your headlight.	(0:16:28.57)
▶ Ruri Tanigawa : Sure!	(0:16:30.32)
▶ Ruri Tanigawa : Watch your head, you two!	(0:16:33.07)
▶ Ruri Tanigawa : Ow!	(0:16:37.11)
▶ Nagi Arato : You okay?	(0:16:38.76)
▶ Ruri Tanigawa : Darn you! It's the same crystal as the other one!	(0:16:41.09)
▶ Nagi Arato : Could this be...	(0:16:44.91)
▶ Nagi Arato : Ruri, can you turn off your light?	(0:16:46.24)
▶ Ruri Tanigawa : Yeah, why?	(0:16:49.20)
▶ Ruri Tanigawa : It's glowing purple!	(0:16:53.51)
▶ Ruri Tanigawa : Wait, what?	(0:16:56.36)
▶ Ruri Tanigawa : Whoa! What's going on?	(0:16:59.26)
▶ Ruri Tanigawa : Is this some kind of magic?	(0:17:01.21)
▶ Nagi Arato : This is a blacklight.	(0:17:03.57)
▶ Nagi Arato : It emits UV light.	(0:17:05.30)
▶ Nagi Arato : Some minerals can be distinguished with this.	(0:17:07.61)
▶ Nagi Arato : Yup, this is likely fluorite.	(0:17:10.26)
▶ Ruri Tanigawa : It's so pretty.	(0:17:13.84)
▶ Ruri Tanigawa : What about these rocks?!	(0:17:16.52)
▶ Ruri Tanigawa : They're not glowing.	(0:17:18.48)
▶ Ruri Tanigawa : Just normal rocks.	(0:17:19.83)
▶ Nagi Arato : Fluorite glows because it contains special impurities, like rare earth elements.	(0:17:21.11)
▶ Ruri Tanigawa : So it's not the fluorite that's glowing?	(0:17:27.13)
▶ Nagi Arato : Nope, that's just the impurities.	(0:17:29.61)
▶ Nagi Arato : It absorbs energy from UV radiation, which is re-emitted as visible light.	(0:17:32.86)
▶ Nagi Arato : That's what makes it special.	(0:17:37.36)
▶ Nagi Arato : The amount of energy determines fluorescent color.	(0:17:41.00)
▶ Nagi Arato : Fluorite emits violet light as a result of the energy lost	(0:17:44.11)
▶ Nagi Arato : when impurities re-emit energy as heat.	(0:17:48.77)
▶ Ruri Tanigawa : Wow... I wish I could take it home.	(0:17:51.41)
▶ Ruri Tanigawa : Wait. That rock I threw away...	(0:17:54.07)
▶ Ruri Tanigawa : Never mind.	(0:17:55.91)
▶ Nagi Arato : Good thing I brought this.	(0:17:56.91)
▶ Nagi Arato : Whoa! Wait, what's wrong?!	(0:17:58.54)
▶ Youko Imari : Hey, Ruri-chan!	(0:18:01.30)
▶ Ruri Tanigawa : Lemme go!	(0:18:02.43)
▶ Ruri Tanigawa : I gotta get my fluorite!	(0:18:03.65)
▶ Ruri Tanigawa : Ow...	(0:18:10.90)
▶ Ruri Tanigawa : Is this all fluorite?	(0:18:21.93)
▶ Nagi Arato : The ore vein was thriving all along.	(0:18:25.62)
▶ Ruri Tanigawa : This is awesome.	(0:18:28.55)
▶ Ruri Tanigawa : It's like we're in space!	(0:18:30.48)
▶ Nagi Arato : Yeah, it's amazing.	(0:18:31.99)
▶ Ruri Tanigawa : You think anyone knows about this place?	(0:18:33.90)
▶ Nagi Arato : I've never heard about it.	(0:18:36.64)
▶ Ruri Tanigawa : Then it's our discovery!	(0:18:38.48)
▶ Nagi Arato : Might be.	(0:18:40.97)
▶ Ruri Tanigawa : ＂Female high school explorer discovers lost planet!＂	(0:18:42.64)
▶ Ruri Tanigawa : Sounds about right!	(0:18:45.88)
▶ Ruri Tanigawa : Imari-san, you're not impressed?	(0:18:53.25)
▶ Ruri Tanigawa : Imari-san?	(0:18:56.19)
▶ Youko Imari : Huh?!	(0:18:57.19)
▶ Youko Imari : Oh! No, it's not that!	(0:18:57.87)
▶ Youko Imari : I just wasn't expecting this.	(0:19:01.64)
▶ Youko Imari : I guess I'm just lost for words.	(0:19:04.96)
▶ Youko Imari : Like, it's just too much.	(0:19:08.24)
▶ Youko Imari : I mean, not too much.	(0:19:11.28)
▶ Ruri Tanigawa : Nagi-san, can you translate?	(0:19:14.45)
▶ Nagi Arato : It means Imari is experiencing something new.	(0:19:17.35)
▶ Nagi Arato : We've got our specimen.	(0:19:29.61)
▶ Nagi Arato : And we were able to locate the mine.	(0:19:31.41)
▶ Nagi Arato : Now we can shed light on what was about to fade away.	(0:19:33.98)
▶ Nagi Arato : That fluorite ore vein really was incredible.	(0:19:38.84)
▶ Nagi Arato : We'll need to research that spot some more.	(0:19:42.74)
▶ Youko Imari : Arato-senpai!	(0:19:45.71)
▶ Youko Imari : U-Um... I don't know if I can be of much help, but...	(0:19:48.50)
▶ Youko Imari : Can I help you research that fluorite ore vein?	(0:19:54.25)
▶ Nagi Arato : Sure. I'll leave this one to you.	(0:19:58.26)
▶ Youko Imari : Leave it? To me?	(0:20:00.89)
▶ Youko Imari : B-But I'm fine just helping.	(0:20:02.86)
▶ Nagi Arato : Its beauty wasn't enough to satisfy you, right?	(0:20:05.05)
▶ Nagi Arato : I can tell you want to learn more.	(0:20:09.70)
▶ Nagi Arato : You want to be part of the knowledge that comes next.	(0:20:11.78)
▶ Nagi Arato : It's good that you feel that way.	(0:20:15.62)
▶ Nagi Arato : If that's the case, don't settle for being someone's hands and feet.	(0:20:18.25)
▶ Nagi Arato : You can't borrow the lens of others forever.	(0:20:23.77)
▶ Nagi Arato : Can you, Imari?	(0:20:27.54)
▶ Youko Imari : I-I want to lead the research of this mine!	(0:20:30.21)
▶ Nagi Arato : Great. You got it.	(0:20:34.78)
▶ Nagi Arato : Then we'll need to gather some more fluorite specimens.	(0:20:38.82)
▶ Nagi Arato : Okay, let's come back next week—	(0:20:42.85)
▶ Ruri Tanigawa : Want 'em?	(0:20:45.37)
▶ Nagi Arato : When did you grab those?	(0:20:46.37)
▶ Ruri Tanigawa : I stuffed as many as I could into my pockets.	(0:20:48.25)
▶ Ruri Tanigawa : Imari-san.	(0:20:54.25)
▶ Ruri Tanigawa : These are for your research.	(0:20:56.86)
▶ Youko Imari : Thanks, Ruri-chan.	(0:21:02.72)
▶ Youko Imari : I'll do my best!	(0:21:05.07)
▶ Ruri Tanigawa : Nagi-san, I wanna find stuff with my own eyes, too.	(0:21:15.01)
▶ Ruri Tanigawa : Don't you know any other places like today?	(0:21:19.79)
▶ Ruri Tanigawa : Somewhere no one else knows about with pretty stones.	(0:21:22.15)
▶ Ruri Tanigawa : I'll be the one to discover it.	(0:21:25.82)
▶ Youko Imari : How can somewhere be unknown, but its stones are?	(0:21:28.22)
▶ Nagi Arato : Want to give it a shot?	(0:21:32.59)
▶ Nagi Arato : There's a specimen I have on hand.	(0:21:35.25)
▶ Nagi Arato : I have a rough idea of its region, too.	(0:21:38.27)
▶ Nagi Arato : And I've figured out how to pinpoint its exact location.	(0:21:40.31)
▶ Nagi Arato : But the locality of the mineral itself is still unknown.	(0:21:43.36)
▶ Nagi Arato : Want in on this, Ruri?	(0:21:47.43)
▶ Ruri Tanigawa : Wh-What kind of stone is it?	(0:21:51.56)
▶ Nagi Arato : Sapphire.	(0:21:54.90)
▶ Ruri Tanigawa : I'm in!	(0:22:03.36)
