Hisatora (久虎 Hisatora) is the uncle of Tatsumi and Kasumi. He is a science teacher who develops suspicious "medicines" and has Tatsumi test them out.[2]


Hisatora resembles a lot to his nephew, as both have messy black hair and tired golden eyes. Due to his scruffy appearance, he is constantly mistaken as a pervert, manly by Tatsumi's classmates.[3]


Hisatora is very dedicated to his work. He continually develops suspicious "medicines" and has Tatsumi test them out, who always refuses but ends up accepting because Hisatora threatens him with leaking out information when he was in seventh grade.[2]

Tatsumi tests the "medicines" on Wakasa, who suffers from diverses changes such as going back to be a baby (not in appearance, but in personality),[3] be more manly and being stuck in the tub.


  • In Chapter 57, he discovers the existence of Wakasa but he forgets about it the next day because he was drunk and can't remember anything.[1]
  • He has a key of Tatsumi's house.
  • He is the younger brother of Tatsumi's father.
