Tsukuyomi

Tsukuyomi is one of the Next Dolls created by Promestein. She was specifically built to defeat Tamamo.

At the end of Chapter 2, after Ilias declares war and Promestein lays siege on the Monster Lord’s Castle, the scientist presents Tsukuyomi, who mentions that tonight is a full moon.

Continuing on in Chapter 3, Tsukuyomi looks on as the battle progresses. However, after Tamamo forces Promestein to order a retreat by scaring the lesser chimera, Tsukuyomi is extremely dismayed and ashamed, unable to fulfill her purpose in defeating the Heavenly Knight.

Trivia

 * 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.
