Agito never seems to recognize Yayoi without her braids, always yelling who she is whenever she bothers him with her hair down. While in training camp, Yayoi fretted over Agito who was overworking himself to produce a stronger Fang. Emily convinced her to kidnap him while he was asleep and bring him somewhere relaxing to help soothe him. Oddly, when Agito woke up (tied up) on a boat in the middle of the lake with Yayoi, he didn't insult her or use his usual profanity, instead keeping quiet while she told him a story about the lake. When Lind appeared during the underwater battle against Orca, she kissed him to give him her air. Orca, annoyed at her interference, slashed her face with his AT, after which Lind complained that Yayoi wasn't that important to him in the first place. Agito's anger flared up at this, causing him to force through the mental cage Lind had trapped him in and regaining his body.
Yayoi has recently become Agito's tuner but she mostly acts as an observer during Kogarasumaru's battles.
