He is likely the basis of Osamu's character design. Katagiri along with the rest of his Unit Yukimura, Toichiro, Karin and Asumi are the main cast of Ashihara's one-shot "Room 303" which has a surprisingly cold and dark tone. There are a few character designs from these guys that Ashihara re-used for other characters in World Trigger.

Lastly, Mira from Aftokrator is an antagonist in Room 303. Or rather, a character with her exact design. Her name wasn't revealed in Room 303. It's good when authors recycle good characters from the old series or one-shots.
