There's a character in Danganronpa 1 called Aoi (pronounced "owie") who Joe decided was his waifu for the game. Whenever he saw her, he'd say "Hey Aoi".[1] He says the same thing to whoever his waifu is in whatever other games he plays. Sometimes Joe calls boobs "Aois".

Aoi is represented by the emote jphJeAoi.
