UTAU wiki


Koru Fivet, also called Goshima Koru (五島こる (ごしまこる)), is a voicebank for the UTAU program.


Koru is probably non-human. They have the INTP personality. They are an eccentric and dramatic person that hardly ever smiles. They're a villain that wants to rule the world... or at least, that's what they say. They enjoy creating evil plans make the things/people they hate "disappear"... but even if they act like they're right and it's what they want, they feel that someone must stop them so they can't carry out their plans. For that reason, they're constantly looking for a "hero" that could stop them. In other words, someone that could help them (ironic, isn't it?). Sarcasm is their motto, and they really enjoy using it.

Koru is a dreamer and considers themselves a creator. They enjoy doing magic tricks, usually with Haruka and Mx. Balkyoo as their assistants. They are a bit demophobic and kind of misanthropic. Koru has some kind of "joke" with rubber ducks... for that reason, they have a lot of them. A closet... full... of them. And they still think those are not enough. Some Timeloids call them "Dr. Rubber-Duck", "The Ducker", "RD" and similar stuff.
