Hiyori tries to adjust to her new form, realizing her human body falls asleep when she leaves it. Yato says he cannot help her until he acquires a new Regalia. Hiyori searches for a new Regalia for him, assuming it can be a Phantom. Due to this misconception, she and Yato are chased by a Crab Phantom. Yato, protecting Hiyori, incurs blight, a wound that can spread if left untreated. He explains that Hiyori's tail is her lifeline to her physical form; she would die if it was severed. After spotting an uncorrupt innocent spirit, Yato adopts it as his new Regalia and uses it to defeat the Crab Phantom. Yato gives his Regalia the name Yukine, who reverts to a teenage boy when his name is spoken.
