Ponkotsu-Chan Kenshouchuu

Briefly about Ponkotsu-Chan Kenshouchuu manga:

Yumesaki-san has a problem. Every day she is given a new, random supernatural ability by an anonymous person called God. But for what purpose? Murakami-san is Yume's childhood friend and probably the only one that has been with her through all her super-induced problems. He also happens to have a few supernatural abilities of his own, but they aren't as flashy as Yume's. Together with their other high school classmates, Yakumo and Nabeshima, they fight off all the abilities bestowed upon them (and sent their way) by searching for answers in this supernatural world.
