Kasane, Teto

重音テト

She appears on two bottles of MEIKO's sake: one labeled "重音てと", the other labeled with her name in katakana, "重音テト"; she also appears with Haku Yowane in another chapter.
Teto is a 31-year-old chimera girl who was born as a joke by users of the NicoNicoDouga forum. She loves eating baguettes and has a close relationship with Ted Kasane and Ruko Yowane.
She is depicted as more innocent than Miku Hatsune. Teto is cheerful and eager, though she may be naughty at times, perhaps inspired by her mischievous roots from Doraemon. She is also depicted as a Tsundere, but to a gentler extent, unlike Neru Akita. Teto gets very angry or sad if someone has bread and does not share it with her. She enjoys teasing people to show she cares about them, since she does not want to show her love. She can get out of control if she has not eaten bread for one day. Obviously, she does not act or sound her age for a 31-year-old girl; thus, her human age is more believed, and the depiction as a 31-year-old girl is often dismissed as artifacts from the users of vip@2ch who created her. There are also persisting rumors of Teto's wings and a tail. She may or may not be aware of her own Chimera form.
