Chapter 108: Something Important to Asa

Asa confronts Yuko over the morality of her killings, but Yuko defends them, arguing that slaying bullies as a devil would terrify cruel students across Japan and let her become an icon on par with Chainsaw Man. She explains that the Justice Devil demanded no payment, instead granting her only a heart radiant with justice. Turning to Yoru for guidance, Asa learns that any possession can become a weapon by touching it and speaking its name. She removes her uniform and reshapes it into a sword, then cuts across Yuko's legs, though at first the strike appears to do nothing.

Moments later the delay breaks and Yuko is rent into countless fragments, exposing the genuine force behind Asa's blade, a result that stuns Yoru. Asa reveals the dress carried deep meaning because her mother had given it to her, which lent the weapon its strength. As Yuko expires, a woman with ringed eyes appears, introduces herself as Yoru's elder sister, and offers to restore Yuko to life. With Devil Hunters closing in, Yuko swells to an enormous size and smashes her way out through the building.

Yuko frames her devil powers as a path to becoming a justice symbol rivaling Chainsaw Man. Asa transforms her mother's uniform into a sword, its sentimental value translating into devastating cutting power that shreds Yuko. A ring-eyed stranger who claims to be Yoru's elder sibling appears and promises to revive the dying girl. Yuko then balloons in size and erupts from the school as hunters arrive.

Set during the Justice Devil arc in Volume 13. The chapter introduces the ring-eyed woman later identified as Fami, and establishes that the emotional worth of an object determines the strength of Asa's weapons.
