Kanon Hisui

Kanon has long hair styled outwards with half twin tails that look spiky, but not like typical cowlicks.

She usually wears a black sailor uniform over her green squad suit.

Her ribbon is usually light green in color drawings, but it appears red on the cover of volume 7.

She always wears white gloves unless she is eating.

Kanon's skirt was originally knee-length, paired with white knee socks and loafers.

As the story goes on, she wears different kinds of sailor uniforms borrowed from her friends, and her skirt gets shorter.

She always wears shorts or leggings underneath for modesty.

Kanon is a top-ranked and skilled fighter despite being a teenager.

She is the direct boss of Hibiki Sakurama (actually Footsoldier D in disguise) and Angel Usukubo in the Green Division.

Kanon is tough and speaks harshly, but she cares deeply about her team and regrets losing members in battle.

Though she rarely shows it, Kanon quietly admires the Green Keeper.

She wishes she could have a normal schoolgirl's life, so she treasures wearing her sailor uniform.

Kanon follows her own strong sense of right and wrong, often hiding her softer side.

When she was 8, Kanon's house was attacked by monsters, and she lost her family.

She was rescued by Sōjirō Ishikawa, a Green Division trainee, and since then calls him by his first name.

Afterward, she was taken in by the Komuro family, who were close to her own.

At age 8, Kanon was questioned by a Monster Protection Association member while talking to Sōjirō.

The man defended monsters, making Kanon angry enough to attack him, which made her realize she could not live a normal life.

She asked Sōjirō to help her join the squad and passed the test at just 10, the youngest ever to become a squad member.

Kanon has a rare body trait: she can swallow and then spit out objects like knives for combat.

She has many small knife gadgets that she hides inside her body, unlike the usual larger squad weapons.

She has a special replica known as "Ukemochi"—a mask-like item fitting her lower face.

With this, she can bite and break almost anything, and even tear through space to attack.

She only uses the mask on monsters or humans allied with monsters, never on regular people.

The cartridge needed to power the Ukemochi replica is hidden inside her.

Kanon was close to Sōjirō Ishikawa, who saved her and later inspired her to join the squad.

She lived with the Komuro family, her childhood friends.

She cares about her team, especially Hibiki Sakurama and Angel Usukubo.

Though she regrets losing Sōjirō, Kanon still tries to help and protect her friends and teammates.

Kanon also has a complicated bond with Footsoldier D—she knows his real identity, keeps it secret, and decides to stay by his side to learn more about him.

Childhood Tragedy and Joining the Squad

Kanon lost her family in a monster attack at age 8 and was saved by Sōjirō Ishikawa.

Unable to return to a normal life, she asked Sōjirō to help her join the squad.

She passed the entry test as the youngest member ever at 10 years old.

Finding Her Own Path

The sailor uniform Kanon wears was meant for middle school, showing her longing to be a regular girl.

Her wish is put to the test when a monster general creates a fake school and traps her in a mind loop, trying to brainwash her.

With Hibiki Sakurama's help, Kanon breaks free, fights the monster, and throws away her original uniform as a sign of moving forward.

She then starts wearing uniforms borrowed from friends, especially Noa Hagino.

Relationship with Footsoldier D

Kanon witnesses Footsoldier D in his real form while escaping brainwashing but pretends to forget, hiding the truth from everyone.

After being rescued multiple times by him, she decides she can't forgive all monsters but wants to understand this mysterious soldier.

She continues to work side by side with him without exposing his secrets.

Battles and Captivity

Kanon once fought alone against multiple members of the Monster Protection Association, even those with upgraded replica masks.

Though she defeated most of them, a boss’s special power led to her capture.

When Hibiki Sakurama surrenders to save her, she is spared and kept captive.

Breaking Free and Forming a Team

Footsoldier XX later breaks Kanon out of captivity.

Kanon helps Footsoldier D during a tough battle while revealing that she knows his true face.

From then on, they form a team, fully aware of each other's secrets, but continuing to fight together in the Green Division.

Kanon's first solo cover is on volume 7 of the manga.

She is one of the only people who knows Footsoldier D's true identity.

Her debut episode is episode 63, titled "Kanon Hisui, Age 8."

In her earliest appearance, her outfit was orthodox, but it kept changing with every major arc.

Kanon is a key character in GO! GO! Loser Ranger! by Negi Haruba and is considered one of the closest partners to the main character, Footsoldier D, after many shared events.

She is respected and feared for her unique fighting skills and her mysterious, honest personality.
