KeA's Penguin Costume

In "The Legend of Heroes: Trails to Azure," one of the decorations you can get for KeA's room is a Zwei II Penguin costume (a reference to the Nihon Falcom game Zwei: The Ilvard Insurrection) which she can wear. If you obtain all her decorations, then you get a scene in which she puts it on. Lloyd declares that his heart can't take it, while Elie, Tio and Noel are overwhelmed and embrace KeA in a hug attack that causes Wazy to declare that there have been multiple victims and that the cause of death was a cuteness overload. It is said that the girls eventually regain their senses, but only after a while. Following this, an indefinite ban is placed on Penguin KeA for the sanity of everyone in the Special Support Section.
