Kotori is one of the most intelligent and creative girls in Millennium High! She knows anything and everything and sometimes go on longwinded speeches to explain something as simple as canned food containers. She’s completely oblivious to some things like love and whatnot. Kotori is also an expert engineer along with Utaha and Hibiki. She actually believes knowledge is stored in her bust, which is why she believes she’s so well-endowed. She’s from Blue Archive.
