"Hai!"（はいッ）is a unique speech bubble used by Ryūnosuke Naruhodō in Dai Gyakuten Saiban: Naruhodō Ryūnosuke no Bōken. It is used to formally address or acknowledge the other trial participants early on in the game. It is the speech bubble he uses the most in The Adventure of the Great Departure and The Adventure of the Unbreakable Speckled Band, but is only rarely used later on in the game.
