The World I Transmigrated to Has Serious Problems

I woke up and found that I had transmigrated.

No golden finger, no System, just a petrified Ultraman transformation device in my arms.

This world has monsters, and I have a younger sister named Tsuchima Mai.

I attend Toyosaki Academy, but there’s no frequently appearing upperclassman, no blonde, and certainly no Megumi Kato.

Wait, who’s that girl standing downstairs in a red kimono?

(PS: This is an old book. The even older one, My! Transmigration! Invincible!, is complete. My new book, Going on a Rampage in Another World with FGO, is currently being serialized!)
