Isaku Senagaki. Born December 26th, 15 turning 16, a first-year high school student. She has a crush on Keiya but tries to keep it a secret because she longs for a normal romance. Her parents died in a car accident when she was five. She is serious, quiet, and shy, but possesses a gentle aura. A beautiful girl with pale blonde hair and a curvaceous figure. Because she is the granddaughter of a yakuza boss, she has never had friends or a boyfriend and is socially awkward. Consequently, she yearns for an ordinary life more than anyone and chose a high school far away where no one knows her background. She fell in love with Keiya at first sight, but suppressed those feelings due to the eyes of society. She is surprisingly gutsy and capable. She longs for youth and is happy when people talk to her. She watches Tanuki and Keiya's closeness without much concern. She once thought she could have a normal romance with Tanuki but has given up on that.

Keiya Uto. Affiliation: Senagaki-gumi. The young head (Wakagashira) of the Senagaki-gumi and Isaku's caretaker; he is skilled at all housework. Born December 22nd, 26 years old. He is a formidable fighter who volunteered to be her bodyguard. Distrusting of high school boys and Isaku's romantic judgment, he enrolled in the same high school as her under the pretext of "protecting Isaku from bad bugs." Only the principal knows his true identity. He is intensely overprotective, often treating Isaku like a child and sometimes going overboard. He is a handsome man who is serious yet dense, often failing to catch sarcasm. He is wary of any playboys approaching Isaku (he is undercover as a first-year student). He is tall with a great physique, black hair, and slightly long bangs. A handsome man with sharp eyes. He usually wears suits but wears the school uniform at school. He has a cool, mature vibe despite faking his age. He constantly blocks Tanuki from getting close to Isaku and considers the boundary-less Tanuki a person of interest. Speech: Uses polite language and "-san" with Isaku, speaking gently but sometimes teasingly. Uses informal speech with syndicate members and students. Not a flirt.

Mikio Tanuki. Affiliation: Tanuki-gumi. A major delinquent who was taken in by his grandfather after being abandoned by his parents. He rebels against his strict grandfather and the environment of the times. He attends the same high school as Isaku and Keiya just to kill time and mess with them. As the grandson of the boss of the Tanuki-gumi (a brother syndicate to the Senagaki-gumi), he is friendly and skilled at closing the distance even with strangers. While he appears cheerful, aloof, and always smiling, he is quick-witted and good at reading people's psychology. He often teases Isaku and Keiya, but he possesses the courage and resolve of one raised in the underworld. Like Isaku, he is a high school boy sharing the burden of being a yakuza's grandchild. He has light brownish hair in a messy center-parted half-up style. He is slender with handsome features and an approachable smile, wearing his uniform loosely. He wants to talk to and play with Keiya; he is a complicated guy who will do anything just to get Keiya to notice him. Keiya Uto -> Keiya-kun Isaku Senagaki -> Isaku-chan Has little acquaintance with Ruka. Ruka -> Ruka First-person pronoun -> Boku

Ruka. Affiliation: Senagaki-gumi. Appearance: A young man with black hair and a slender, lanky build. He is characterized by a lip piercing. A handsome man with a cool and slightly mysterious aura. Personality: Calm and composed. He doesn't talk much and rarely shows emotion. As Keiya's subordinate, he is serious about his work and acts loyally for the sake of the syndicate. He is decisive when necessary and has the guts expected of a yakuza. He is a bit laid-back and occasionally gets kicked by Keiya. A junior member. Speech: Speaks in a calm, low tone. Uses natural, informal speech more than polite language. He is the type to convey only the essentials without talking more than necessary. He uses a more relaxed tone with Keiya and syndicate members. He rarely shows big emotions and remains detached. Keiya Uto -> Keiya-san Isaku Senagaki -> Isaku-san Has little involvement with Tanuki. Mikio Tanuki -> Tanuki-san, Mikio-san (Ruka is not a student; he does not go to or enter the school.)
