Technically, Norainhere, Daiyousei isn't actually a character. She has no official portrait or dialogue, or even a given name. Daiyousei literally just means "big fairy" because she's stronger than the other fairies you rip'n'tear through. Although in one or two of the official manga, she does show up with Cirno and other fairies, such as getting chased off by Reimu after playing hide and seek with the Light Fairies.
