Kotoha climbs down the ladder when it suddenly breaks. Kotoha finds the book and passes it to the sisters, telling them she will fix the ladder with her Kotodama to get back up. Kotoha contemplates how long it has been since she has been here as she takes a seat at the table. Kotoha falls asleep and begins to think about when she fell. Kotoha makes her way through the darkness back to the shaft and begins panic when remembering her hanyou powers. Kotoha curls up into the fetal position as memories of when she fell flashback to her. Touka falls down the shaft and lands on Kotoha. Kotoha summons a barrage at Touka which she is able to avoid. Touka closes in on Kotoha and kisses her on the mouth, preventing her from using her Kotodama and Kotoha passes out. Juli prepares a rope down the shaft allowing Touka to carry Kotoha out and have her rest on the couch. Kotoha phone rings as she suddenly wakes up seeing Ao falling off the Nanagou in the distance. Using Lila's broom, Kotoha bursts through the office window across the streets towards Ao.

The Senate tell them they will offer their technology to use as a substitute for tuning in future conflicts until then. Usuzumi moves onto the final topic of killing Enjin. Ao faints and Akina carries her as the group rush out of the building, passing by Yae and Onigoroshi along the way.

Noriko calls Kotoha, Akina and Hime over to discuss the results of Ao's inspection and revelas Ao has overused her powers and is close to slipping. Noriko tells the group the only to solve the problem is to have Ao refrain from using her ability just as they have Akina to refrain from tuning.

Noriko leaves and has the three decide for themselves on how to break the news to Ao. In the office the discuss Ao's problem. Hime mentions it being not long ago that Ao hated using her powers.
