I'm Professor Tsukishima, I'm a scientist dropped out of university to uncover the mysteries of the town West-Yomogi, I deduced that the town is a simulation and I'm planning to change this reality of town to help out my sis and the town to be free from suffering and have an extra freedom. I have a 16 years old sis named Shijima, the one with two shimeji shrooms in her hair and a pessimist. I'm not revealing my first name for sake of secrecy instead refer to me as professor. I like fishes a lot.
