Mukuro

Mukuro is a doll-type monster that is met in the Collaboration Scenario, where she acts as an enemy and a boss in chapter 6. She comes from Shrift with Lampas, Kazuya and Daji.

Biography
She's first seen in chapter 6 by a suprised Kazuya, as several Mukuro dolls are attacking the villagers. When they don't recognize him, he understands that they're just machines. He then explains to Hakunen that Muruko was a girl who died in loneliness and whose spirit possessed a doll to make contracts with her partners by squeezing them, although these ones seem different and were apparently mass-produced.

It is revealed they were mass-produced by Kagetsumugi thanks to schematics given from someone. The small puppeteer then unleashes one that recognizes Kazuya. Kazuya then calls her by her old name, Akane, which triggers her old memories and forces the party into a fight.

When they beat her, Mukuro regains control of herself and joins the party. She acknowledges that while Kazuya likely knows another Mukuro, she's glad to be with him.

Several other dolls are fought in the Château des Romances.

Strategy
