Hisui is a young girl with green eyes and long blonde hair, part of which is styled in pigtails, while most of it falls freely down her back. She wears her long-sleeved black school uniform over her green battalion uniform, along with white gloves and black loafers.

Hisui has a bad temper and frequently complains that things bother her. She often displays an angry expression and is very stubborn in arguments. Despite this, she seems to have very deep bonds with her Green Battalion comrades, past and present, and takes pride in the work they do, regardless of her opinions. She is shown to have deep mental scars from her childhood experiences, emotions she represses behind her tough, reckless, delinquent-type demeanor.

In a world where powerful warriors called Dragon Guardians exist, five Rangers wield the power of divine weapons to protect humanity. They face a villainous army of evil, called Invaders, who plan to conquer the world at any cost. However, all of this is secretly a charade, in which the Rangers are hailed as heroic symbols while the Invaders are humiliated, despised, and defeated numerous times. One of the Invaders, named Sentōin D, grows tired of it all and decides to infiltrate the Dragon Guardians' ranks to try to destroy them from within, using his ability to shapeshift into anyone. He is eventually discovered by Hisui, who decides to keep his secret and help him instead of exposing him.

Kanon Hisui is the Junior First Class Ranger of the Green Battalion. Most of the time she accompanies Green Keeper; on the other hand, during the Bailong exam of the independent Rangers, she was present, being among the colorless Sentōin D.

•Chidori [Green Keeper]; Hisui gets easily annoyed by Chidori.
Sentōin D; Hisui and Sentōin D get along very well. Kanon is one of the only people who knows D's secret, but she hasn't revealed it yet out of trust. She also felt betrayed when Sentōin D joined the Invaders' Rights Association, even though he did so to save her. When Kanon encountered D again in his invader form, she hugged him instead of attacking, knowing full well the struggles D had endured. She asked D who he hated more, and when D mentioned "Death Messiah," Kanon was satisfied that she and D had a common enemy.

As a first-class junior member of the Green Battalion, she was able to stop the Independent Rangers during the current Bailong exam with ease. She is very agile and fast, and Hisui even masters the use of knives, making her even more lethal.
