Yoshiyuki Nakajima

Yoshiyuki Nakajima (中島 美雪), referred to by students as Nakajima-sensei, is a teacher at Yezo Agricultural High School. He is one of the first people that Hachiken meets.

Personality
Nakajima is very caring towards his students, helping Hachiken as he passed by and often commenting on the students' accomplishments to other teachers. Despite this, he sometimes breaks bad news right after good news, taking some pleasure in doing so. He also has an obsession over cheese, and keeps a personal room just for it hidden under a trap door; when Hachiken made pizza and needed cheese, he was shown to be very protective of it, only giving in when they promised not to reveal his use of school grounds in exchange for cheese. On the topic of obsessions, he repeatedly will bet on horse races and has never been known to win.

Skills and Abilities
Nakajima is a skilled cheese maker. He is also the councilor for the Equestrian Club, mentoring Hachiken and overseeing Aki.

Mayumi Yoshino
They have a very give and take relationship. For the most part she takes from him, mostly cheese. She'll often ask for him to buy animals for her to make different cheese. He will complain but give in and buy them anyway.

Shinei Ōkawa
During his long amount of time being unemployed and lounging around the Equestrian Club, Nakajima commissioned a raclette cheese oven from him.
