[Crossover] Cutting-Edge Technology Is the Driving Force!

Draws on some elements from Arpeggio of Blue Steel, FGO, and Katekyo Hitman Reborn, among others. The female lead is a self-insert. I finished setting her up, then forgot to give her an ability. But that's not important. Who needs special powers when you have advanced technology?

In a nutshell: Boss Mori, you've lost your SSR.

Theme: Don't let the great angel Oda Sakunosuke die!
