Story
The main character, Yuu Kashiwagi, is an ordinary, extremely normal college student.
He's been living on his own for 3 years, since he left his hometown to take the entrance exam for an urban university. At a glance he looks like a normal college student, but he is an unparalleled lover of cosplay, whether it be career costumes or anime ones.
His dream is to one day get a girlfriend and have cosplay sex with her. Every day, his part-time job earnings go down the drain on cosplay porn, costumes, and materials daily.
Then Yuu one day wakes up, and under his eyes are two beautiful girls.......
Of all things, they're both passionately playing with Yuu's nether regions and sucking him off. But, Yuu doesn't know their names. Their faces aren't familiar either.
......Rather, he probably doesn't know these girls. Family? Relatives? Friends? All sorts of ideas run through his mind but sure enough he has no memory of them.
Asking for their names, one said ＂Arte? Arte is Arte＂, and the other replied, ＂I am Toria. One of the candidates for queen, Toria＂.

＂Understood? Listen well. We are magical girls, from a magical country＂
＂Huh-?　Magical girls?＂
＂Right now, in our country, there is a test to see who will be the next queen＂
＂............＂
＂Hey, are you listening?＂
＂............＂
＂Hey!＂
＂............＂
So to sum it up these girls are...... like that? In their heads, residents of wonderland?
I see... Is that so....... So there really are people who don't understand the boundary between anime and reality.

Thus, begins the extraordinary life of our cosplay-loving protagonist and two magical girls, which got the residents of their apartment involved――――.
