Tsukuyomi

One of the Chimeras, Tsukuyomi was created by Promestein. She seems to be based on the Tsukiyomi-no-Mikoto, a Moon god in Shinto mythology, referenced by her name and the fact she references the full moon when she appears.

Due to her connection with the satellite, it could be assumed she was created specifically to defeat Tamamo, who also shares a connection with it.
