Don’t Toy with Me, Miss Nagatoro (Japanese: イジらないで、長瀞さん, Hepburn: Ijiranaide, Nagatoro-san) is a Japanese web manga series written and illustrated by Nanashi. It has been serialized online since 2017. Some translations of the title replace “toy” with “bully,” for good reason.
Although it is in many ways a slice-of-life manga, there is a definite direction to the plot.
Painfully introverted second-year high schooler Nao-kun avoids social interaction whenever possible, burying himself in art, preferably alone in the art club’s clubroom. Given that he has a metaphoric brightly lit “easily bullied victim” sign floating over him, this is for the best. To interact with other people is to court abuse.
Unfortunately for Nao-kun’s equanimity, first year high-school student Hayase ““Hayacchi” Nagatoro has noticed Nao-kun. She has a use for her “Senpai,” as she calls him.
