Kaeru Batake DE Tsukamaete Japan

Kaeru Batake DE Tsukamaete: The story is about a girl named Sagano Fuu who is in the broadcasting club. They decide they’re out of stuff to talk about so they go out looking for the 7 wonders of the world. They stumble upon some frog shrine and being the typical stupid teenagers they break a stone disk inside of it. The frog god curses them and they all turn into frogs. Suddenly a 3 tailed cat spirit named Touya, shows up and makes them a deal: he will return them into human form but only if they repent by cleaning/taking care of the shrine and the eco system. So from here on Fuu and her dumb male counterparts are forced to stay at the dorm together and take care of the eco system for a month in order to not turn into KeroKoi.
