A living sword similar to Grospoliner and Gesso. Unlike those two, it is an evil sword that thrives on suffering and completely controls its wielder. The only way to break its control is to have the sword deal a deadly blow to someone the current wielder/possessed one loves. Mana wielded the sword before the series, and Katsumi is possessed by it in the later part of the series. Kiddy's intervention broke the sword's control, but she survived thanks to her android nature.
