Synopsis:

This special is set during the Träumend storyline.

After Shinku refuses a brooch Jun wanted to give her as a gift, Souseiseki explains Shinku\’s strange behaviour by telling Jun what had happened a couple of centuries before, when the Rozen Maiden dolls first met.

This is a story of Shinku\’s past, that also explains how Suigintou became a villain and why she hates Shinku so much.
