Personality
Ayase is a very shy and anxious person, and is shy around everyone. She is especially shy around boys her age, as she has never actually seen another boy, who either wasn't her mentor, or pupils of said mentor, which causes her to be very unwilling to look one in the eyes. However, it has been shown when holding a sword, her shyness and anxiety passes as though it was never even there, as seen when she showed a vast amount of capability when training with Ikki.

She also has a dark and deceptive nature as shown when she tricked Ikki into activating Ittou Shura a few hours before their match.

History
Ayase has been training swordsmanship under her father, Kaito Ayatsuji, since childhood and greatly desire to become a great swordsman like her father. 2 years prior the series, the Ayatsuji Dojo, a dojo started by Kaito was challenged by Kuraudo Kurashiki who beat up all of Kaito's students severely. When Kaito accepted Kuraudo's challenge, Ayase initially protested before giving up and decides to act as the judge to their match and was greatly shocked when Kuraudo crushed his father's ribs in front of her. This event led to Ayase having an immense hatred towards Kuraudo. Following that incident, Ayase continued to challenge Kuraudo time and time again but to no avail as she was easily toyed with everytime to the point where Kuraudo lost interest in her and no longer accepted her challenge.

Disciple, Encounter and Betrayal
Ayase is first seen, after being caught by Ikki Kurogane, in the hospital, after she injures herself, running away from Ikki who catches her stalking him. She explained that she only stalked Ikki, to help her with her training, and Ikki gleefully agrees. She then goes to the forest with Ikki and friends, where Ikki helps develops a better form while wielding her sword, making her reaction time far faster then before.

Ayase then receives a message on her student notebook, which told her, her tenth opponent for the participation round, Ikki. Ayase, after not talking with the group for a while, then invites Ikki to the roof tops, before the day of the match, which he comes alone to.
