In this episode, Yomi and Kagura save an innocent woman from an evil spirit in the line of duty. After the mission, the swordsmith Michael appears at the exorcists' HQ and offers to repair most of their weaponry, leaving them with only a few temporary spirit-killing weapons to use. Even so, Yomi takes Kagura on another mission through the subway, where the same innocent woman from before appears as a "Class D" threat after committing suicide on the train tracks.
Yomi fights against the evil spirits, but Kagura can't bring herself to kill any of them, as they look like humans to her. Finally, Kagura's father appears and destroys all the demons with his own massive spiritual beast. After the battle, he scolds Kagura for backing down and tells her to "grow stronger" before he leaves.
