Smile smiling

"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 to- 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. He also appears in the basement of the corrupted school where he will attack Sabitsuki upon her entering the room while laughing manically. When this school is visited by Rust, however, she kills him.

His latest appearance is in the Disposal area. Smile retains his name and hairstyle, but lacks tattoos and wears simple black clothes. He stands with two other beings dressed like him and a Cleaner in an unreachable room of the Disposal area. Sabitsuki can attract his attention by firing a warning shot from her Handgun, causing him to look over his shoulder. Interacting with the obstacle between them shows a close up of his face, then he turns back to whatever the four are looking at.


  • When hit with the pipe, Smile actually used to speak. However, his speech was removed in version 0.18, and now he just laughs at Sabitsuki. Some decipher his line as:
    • "You're a sick girl, but I'll see you again";
    • "You're a strange girl, but I'll see you again";
    • "You're safe here, but I'll see you again";
    • "You sing girl, potassium onion´╗┐" and so on.


  • Some speculate that Smile and Sister are related to Sabitsuki in some way, either by blood or relation in that they possibly shared the same illness.
  • Another theory is that Smile was one of her friends who she might have grown up with.
  • Maybe Sabitsuki and Smile have done something wrong together. This could possibly explain the Black Hood, Iron Pipe and Tattoo effects.
