He is a doctor at the Hinamizawa clinic and is a very respectable man, except for his perversion. On his days off, he is also the manager of the Hinamizawa Fighters, and is taken care of and very well respected by the villagers. The Irie Institute was established in Hinamizawa where he and Takano worked together on researching Hinamizawa Syndrome, having experimented on various people that were kidnapped under the guise of Oyashiro-sama's curse.
