My name is Ritsuka Morning Star, son of Sensei Morning Star. Yeah, that Sensei—the guy who somehow keeps this crazy city from collapsing under its own absurdity. I never expected to end up in Kivotos, the so-called "City of Angels" (or as outsiders call it, the "Nation of Gun-Toting Schoolgirls").

But here I am, all because my dad suddenly remembered he had a son and dragged me into this madness. Turns out, being the only male student in a city where the schools have more political power than governments comes with its own problems. The demographics? 60% female students, 20% human-like talking animals, 10% robots, and another 10% of complete unknowns. Oh, and polygamy is legal here for some reason.

So, why the hell am I enrolled in every school?! Seriously, what kind of system is this?!

And if that wasn't enough, my new roommate is Mika. Yes, that Mika—the girl who can destroy entire armies when she's having a bad day. Now, I have to deal with haloed girls, heavy artillery, killer robots, superpowers, and potential world-ending disasters.
