Byouko Byouinzaka stands out as one of the most enigmatic figures in the Deadly Artifact series, operating as a member of the underground syndicate known as 'GOSSIP' alongside her elder sister. At a tragically young age, she awakened to the syringe-type Deadly Artifact 'Dissecting Poison,' only to lose control of its lethal power and inadvertently kill her own parents. That irreversible trauma stunted her emotional growth, leaving her perpetually silent and devoid of visible expression. Beneath her frigid exterior, however, lies an overwhelming attachment to her sister—making her a uniquely dangerous Rights Holder whose fragility and lethality exist in unsettling balance.
