Appearance
He is a lean, muscular young man with tanned skin, black messy hair, amber eyes, elongated fangs, and pointed ears covered in black fur. He has a scar on the left side of his hip from being shot as a child, and Hana discovered him there. In his half-wolf form, he has black fur at the back of his neck, black fur on each side of his face in the shape of three triangles, light gray fur all over his arms and legs and black streaks next to his knees in the shape of two triangles. His nails become longer like claws.

He wears a red collar around his neck with yellow diamonds and a yellow line at the front. Werewolves have to wear collars so that if they disobey, they get an electric shock. They start to get more rights at the start as they’re allowed to go in public and go to school with their masters. His outfits changes a lot but his school uniform consists of a white button-down shirt with short sleeves, a light blue tie, gray trousers and white loafers. When it becomes colder, his school uniform consists of a white button-down with long sleeves, a light blue tie, a navy sweater-vest, gray trousers and white loafers.

Personality
He is a very happy and friendly personality. He is a kind and loyal werewolf. He is very respectful to Hana, her father and Miho, another werewolf in the household. In the beginning, he has a strong dislike for other people, growling at them to intimidate them, when he actually gets scared easily. Haru gets lonely when he’s home alone for too long, so he was really excited when he got to go to school. Haru has an overall calm demeanour, but has a short temper, especially when it comes to someone hurting or upsetting Hana. Haru builds strong relationships with the people around him, and would do anything to help them. Haru is very protective of Hana and becomes sad and distant when she starts to date Jeff.

He thinks of the people at home are like family. He has an informal relationship with Hana as he calls her by her first name and not ‘master’. He also calls Miho, sis, and Hana’s father, dad.

Trivia
It is revealed that he likes Hana (although a werewolf and owner relationship is forbidden.) He shows a strong dislike towards Jeff and Hook, but ends up becoming friends with Hook at the end of the story.

It is later revealed that Hook and him are twin brothers and both were born as wolfs with heterochromia.

He becomes involved with the government after Hooks' death at their hands. It is revealed that both of them were born as wolves with heterochromia, but his blue eye disappeared when he was younger. Due to the pain of losing his brother, it returns and he launches a massive attack against the military, who at the moment had all werewolf’s look up and was in the process of killing them. The public believed it was because they carried rabies but the truth was the government was trying to hide the werewolf fighting arena from were Hook had escaped previously.

After fighting all night long, exhausted, he goes to the place where his family first found him as a baby, but the military had tracked his steps and was waiting with a firing squad. They shoot him several times until Hana arrived with her dad and intervened, however, he was left severely wounded. Hana begs him to stay with her, he however could feel his death coming and tells Hana that he loves her and that someday they would be meet again in a place where they can be in love without being judged for it.
