"Smile" is a file-given name for a recurring black-haired NPC that appears at several points in .flow as of v0.1.
Not much is known about him other than the fact that he looks similar to, and has identical hair as Sabitsuki and Rust, apart from it being black. He appears in a room in the school with several children where he smiles if Sabitsuki takes out her iron pipe. He appears on the roof of the school where Sabitsuki will get the tattoo effect upon interacting with him.
He appears in a room with another black-haired NPC known as Sister where he will laugh if Sabitsuki attempts to hit him with the iron pipe. Finally, he appears in the basement of the corrupted school where he will attack Sabitsuki upon her entering the room while laughing manically.
