I had a bigger synopsis typed, but shit happened, sooooo
The world has been infected by the 'nanovirus', about which almost nothing is known beyond the fact that victims have a random chance of going batshit insane and transforming into powerful, rampaging monsters with almost no warning at all. One person is unique, however, because he is a a teenager mysteriously connected with the explosion that infected the world. He is very much infected, but he can control it, warping his body into badass implements of destruction at will. He's working for the government as a top-secret anti-virus weapon.
It's pretty cool, you guys can check it out. Rex actually has routine issues controlling his powers, and he doesn't get some sort of powerup through sheer determination.
What is your guys's view on Tsunderes?
