Believe it or not there are adult characters in this story! And they're the last of the characters~ Left to right: Hachiro, Tadashi, Nori, Takeshi, and Kenta.

Hachiro was a redesign of an old greaser character who actually was a student but I decided that teacher was better lol. He runs the auto shop and teaches kids all about cars! Yes~ He was a delinquent back in the day(like all of the teachers ;3) and his favorite past time was working on cars and drag racing. He was a little shit back in the day! But after graduation he decided he liked auto body a lot and decided to go into teaching! He's known as a teacher that doesn't take shit from his students but he's still likable for listening to his students whenever they need help. Let it be personally or on their assignment.

Next is Tadashi! He was Hachiro's best friend back in the day and the two were a pair of nightmares. After Hachiro went into auto body Tadashi took a surprising route. Physical education! He was in track and field when he was a student and teaches the kids sports and moving your body is fun and healthy. He also smokes like a chimney :P

Third is Nori. He's the cafeteria chef aka the lunchlady(as all the little ruffians would call him). He's an old chubby man that loves to cook and feed hungry growing boys! He actually teaches a cooking class and has them help him cook lunch and serve. He fully believes that a good meal makes you feel good. He puts lots of love into his food. He's a cute old man and a lot of students crush hardcore on him XD

Then there's Takeshi, the headmaster of the school and Ryuunosuke's father(GASP!). He's a hard ass that's feared by most of the students in the school. He actually does allow the fights as long as they're one-on-one and fair. And he does because in his younger years he was a tough guy that constantly fought. But he turned himself around after his girlfriend(and first love) left him. It was at the end of Ryuunosuke's middle school year did he find out he had... because he went to his old love's funeral. DRAMAAAAAAA~ Takeshi isn't a very emotional guy but he's trying for his son.

And last but not least, Kenta! He's Haruko's father and other then the eyes the two are a spitting image of each other! He had divorced Haruko's mother for years now and he'd get to see his son every summer until one summer he came to stay for good. Haruko was acting like a monster so his mom dumped him off on Kenta. Kenta didn't mind since he's a lonely old man and Haruko wouldn't have it any other way since he loves his old man(sadly Kenta's ex wasn't all that great). Kanta is a laid back and chill guy that loves listening to metal. But despite his intimidating demeanor and blaring music he's actually a big cinnamon bun.
