Yuichi Katagiri

is a fellow scientist and brother of Professor Jiro Katagiri.
==History==
Yuichi goes to the Daitenku Temple to ask for help retrieving his brother, Jiro, from the dream world at the sleep center secretly run by Igor, saying he should be working, but quickly gets possessed by the Grimm Eyecon, Wilhelm Grimm saying Jiro needs a chance to enjoy himself before jumping out. Accompanying Takeru and the others to the center, he joins them in the dream world, finding and telling his brother to leave, but gets possessed by Grimm again, Wilhelm letting him enjoy this world with his brother before Jacob Grimm wrestles for control, echoing Yuichi's original sentiment, the struggle ejecting Grimm completely. After Igor attacks and Ghost's Grateful Damashii destabilizes, Yuichi is grabbed by the Denki Gamma.
He is freed by Ghost Mugen Damashii, quickly following Takeru out of the dream world, only for Igor to take Jiro and Akari's bodies hostage. Back at the Daitenku Temple, he says that he wishes Jiro put his unique sense of creativity towards science seriously; Takeru questions why science can't be for fun. When the group is lured to Jiro and Akari's bodies, he rejoins Takeru in the dream world, but when Igor uses the stolen Grim Damashii's power to change it into a fairy tale land, Yuichi is turned into . They track down and again confront Jiro, but Akari reminds the brothers of the time they showed her as a child how fun science was, Yuichi remembering how fun it can be and the two making up. After leaving the dream world, they and Akari hold a science demonstration for children at the university.
