Cherna Mouse

A member of Team Bell who is innocent and selfish. She can grow extremely large with an unknown limit, and her physical ability also increases somewhat in proportion to her size. Until 30 meters, there is not much energy loss, but after that, she will suffer from exhaustion that is proportional to her size.

Under instructions from Melville, Cherna Mouse uses her powers to gatekeep the other parties from grinding on the monsters in their territory.
