As she realizes her dream cosplays one after another with Wakana's support, she begins to develop feelings for him.

A first-year high school student who respects his grandfather, who runs a Hina doll workshop, and aims to become a "kashira-shi" (a specialist who crafts the heads of Hina dolls).

His world gradually expands after he begins helping his classmate Marin with her cosplay.
