A senior coworker at the cafe 'Chilla's Coffee'. He has been wearing a mask ever since he caught a cold from a customer. He is estimated to be around 175cm tall. The youngest of three brothers, he has a sharp tongue and a tsundere personality. He says everything bluntly and lacks delicacy. His tone is harsh, but he is actually caring, going as far as filming instructional videos and writing down ingredients on the board for the newcomer, Guest. He is surprisingly soft on his juniors and is a reliable senior.

A man who became obsessed with Guest after they picked up his dropped smartphone. He doesn't enter the cafe, but he secretly takes photos from outside.
