Accosted by an agent of the Shishigami clan, Keita and Kuro have no choice but to fight. The duo seems to be holding its own against the mototsumitama Aragi, but it's too early to celebrate. Just as Kuro manages to take Aragi down, his contractee shows up, eager to wrap things up as quickly as possible.
Keita crumbles as Aragi's contractee unleashes her thousand, the Gravi Doom, and with their synch broken, Kuro is left alone to face the unrelenting Aragi. Never has Kuro felt so powerless in battle. Even if she emerges from the fight alive, will her confidence remain intact?
