The Zerozaki Clan is a family of demonic killers, ranked third among the Killing Names.


Having just become siblings, Zerozaki Hitoshiki and Mutou Iori attack Aikawa Jun—Humanity's Strongest Contractor—with the best intentions. But, as a result, get caught up in her work! They're headed towards the domain of the second-ranked Killing Names, the Yamaguchi Folks, on the island of Taiyakujima. Therein lies the Lifelong Undefeated Crystal Kaiser, Rikka Kajumaru.
