I Actually Transmigrated into the Game I Made

What the heck! What's going on?

I actually transmigrated into a game I made myself.

Did I just screw myself over?

And to make matters worse, I made a crossover mobile game. Damn it.

I have to defeat Harumichi Bouya first, the greatest man in Hoya.

Only then will I have a chance of staying alive.

What a messed-up worldbuilding, what a messed-up world.
