Personality
Kotori is a sweet and caring person. She can be very doting towards Honoka and Umi, but mainly Umi due to the fact they have feelings for each other. As she took her Muse Ranger training early with Umi, she soon learns that she is ill-prepared to do the many dangerous tasks she is facing. She feels that she's slowing the team down a lot and blames herself for getting Honoka and Umi almost getting killed just to protect her. As the series progresses, Kotori improves herself to be on the same level as everyone else.

Background
Kotori's father one of the scientists who sacrificed their lives in imprisoning Professor Yaruzo Zarak and his Viruszoids in an alternate dimension, leaving her raised by her mother. At an early age, Kotori began her training to become a Muse Ranger alongside her childhood friend Umi Sonoda, but kept it a secret from Honoka. Kotori could not keep up with Umi but managed to become μ's3, equipping the μ'sDaggers and the μ's3 Plane.

Alongside Umi, they revealed their identities as Muse Rangers to Honoka. μ's3 gets impressed with μ's1 fighting Virus Hacker despite it being the latter's first time. μ's3 then summons μ's3 Plane to form the μ's Battle Robo to defeat Virus Hacker for good. Six more girls joined the team to form the complete nine-man Muse Ranger Team.

Along side μ's1 and μ's4, μ's3 fought against a brainwashed A-RiseZ (Anju Yuuki) and saving her and her teammates. Anju noted how Kotori could become Principal of Otonokizaka but the latter tells her its not gonna happen.

Kotori developed a strong rivalry towards Virus Agent Regina. In Mission 36: my Strength Comes From Within, Regina nearly kills her until Battlizer μ's1 and S.W.A.T μ's4 intervene, injuring them. Kotori then realizes that she's slowing down her team and relies too much on Honoka and Umi saving her. She then decides to face Regina alone, telling her teammates that she is tired of always being a burden to them, however, Honoka and Umi convinced her that she is not a burden to them and shouldn't push herself to the limit. With that, S.W.A.T μ's3 is able to defeat Regina with Battlizer μ's1 and S.W.A.T μ's4, thus giving her more confidence in battle.
