Machine-Doll wa Kizutsukanai

Synopsis

The girl whom Yaya saved is Charlotte's younger sister, Henriette, who has made several suicide attempts. Realizing that the attack on the clock tower contradicts Charlotte's nature, Raishin goes searching for her. Cedric sends Charlotte to see Raishin with a warning for him to stay away from Henriette. Frey locates Henriette with her automata just before she hangs herself. That night, Raishin is ready to face the 87th ranked puppeteer who does not show up. Henriette makes another suicide attempt but is stopped by Charlotte. Raishin learns from Kimberley that the Academy's headmaster Rutherford is being targeted and he deduces that the Kingsfort family is involved. The next day, Raishin spots Rutherford by the ruins of the clock tower and sends Yaya to contact Shoko. He sees Henriette headed towards the ruins and when Sigmund unleashes a Luster Cannon attack, the ground underneath their feet collapses causing Raishin and Henriette to fall.
