Story
It's been a little over half a year since Aisaiger destroyed the cult star cluster Darakuza. The Wife Squadron has become widely recognized by the public, and even now that the crisis caused by the invaders has passed, they still occasionally save people from large-scale incidents, and have become public heroes.

Hikari Ousaka, a female student at Seirin Girls' Academy, is one of those who longs to join the Wife Squadron. Due to certain circumstances, she is married to the school's classical literature teacher and is a secret virgin wife, who not only admires them but also dreams of fighting with them someday.
Then, one day, the school's gym teacher suddenly transforms into a monster and tries to rape Hikari. The ugly, grotesquely transformed teacher stands before Hikari's eyes, which are wide open with fear....... The back of the teacher's neck is crawling with ghastly bugs she's never seen before. I can't do this...... Just as Hikari is about to give up, the legendary Wife Squadron appears before her eyes!

＂With your love...... We'll get even stronger-! Wife Squadron, Aisaiger!!＂

＂N...... no way, am I dreaming......!?＂

Now, the battle with new invaders, the 'Living Machine Empire, Nekuroia', has just begun!
