Tachibana Isana from Yuzuriha no Uta -Inouryoku Soshiki Hanzai Taisaku Bu: Tokushu Kidoutai Dai Ni Ka-

A rookie officer, assigned to the second division of the Special Riot Police not long ago. Among the officers, she is an unusual case: she attends an academy while also serving as a Special Riot Police officer at the same time. Isana doesn't say much and appears to be cold. As a result, she gives off the impression of being difficult to approach, but in reality, she is a kind and cheerful young lady who simply struggles to express her feelings. She had awakened her Special Power in early childhood. In the past, she had been in a lot of troubles due to her latent power, but Ayato saved her.

The fact that she was enamored by her savior, Ayato, played a big factor in her enlistment in the Special Riot Police. Among the officers, she is especially close with Kotetsu and spends a lot of time with her. When cases unfold before her eyes, Isana grows as an officer and a woman thanks to the influence of emotional Kotetsu, lessons from adult seniors, and confrontations with people and Special Holders.

As a Special Holder, she has the power of swiftness. Her forte is cutting enemies with her Japanese sword, making use of her godlike speed. In truth, she uses the same style as Ayato because she is enchanted by him. Even among the officers, her instantaneous force is exceptional. As a result, in missions where a quick solution is required, such as hostage delivery, she is extremely valuable in attacking swiftly and rendering an opponent powerless.
