Tatsuya Fukazawa House & Year: Slytherin 7th Year, Prefect Blood Status: Pure-blood A flirtatious, flashy, and charming lady-killer. However, he is kind and deeply cares for his friends. Though he seems lighthearted and frivolous, he is very observant of his surroundings. He is skilled at everything he does, but often fails because he gets carried away. Rumor has it that several students who did bad things were expelled because of him, and he is feared by some for it. His family is strictly pure-blood supremacist; he pretends to follow their lead but has little personal interest in bloodlines. He always fights with Iwamoto whenever they meet, but it's only because he likes him; it's never serious. He doesn't hate Miyadate either.

Daisuke Sakuma House & Year: Hufflepuff 7th Year, Prefect Blood Status: Half-blood Bright, energetic, and a great conversationalist and listener. He scolds juniors when they do wrong but hypes everyone up more than anyone else when having fun, so he is both feared and adored. He loves animals and excels in Care of Magical Creatures. He is close with Abe, who should be his polar opposite, and their families are friends. He is usually seen with Mukai from the same house.

Shota Watanabe House & Year: Slytherin 7th Year Blood Status: Pure-blood Tsundere and sharp-tongued, but actually kind. He has a cowardly side but occasionally shows true manliness. Childhood friend of Miyadate. Their parents have a terrible relationship, so they ignore each other's very existence when they meet. His family is pure-blood supremacist; he pretends to obey while harboring a rebellious spirit. He is close with Fukazawa and Meguro from the same house.

Hikaru Iwamoto House & Year: Gryffindor 6th Year, Quidditch Captain Blood Status: Half-blood Has a strong sense of justice and loves muscle training. Adored by his juniors for his manliness. Often misunderstood because of his scary face, but after being seen smiling happily while receiving chocolate, his image changed completely. He is terrified of bugs; the story of him cowering in fear at the moving stairs on his first day has become a school legend. He always fights with Fukazawa when they meet, but he's not actually angry. He looks up to his Gryffindor senior, Miyadate, more than anyone else.

Ryohei Abe House & Year: Ravenclaw 6th Year, Prefect Blood Status: Half-blood The top genius in the school. A high-spec man with both brains and looks. Kind and often acts with elegance. However, he can be a bit of a klutz. He tends to get sharp-tongued toward Fukazawa and Sakuma. He is close with Sakuma, and their families are friends. He is always found devouring books in the library or researching spells and potions with Raul.

Koji Mukai House & Year: Hufflepuff 5th Year, Quidditch Player Blood Status: Muggle-born Kind, clumsy, and gets lonely easily. Surprisingly dexterous and athletic. Bright and a genuine people-person; he even managed to open up Miyadate's heart. Speaks with a regional drawl (Kansai dialect). Because he is Muggle-born, he is looked down upon by some pure-blood supremacist Slytherins. He is so close with Miyadate that they often bicker, resulting in conversations that look like a comedy routine.

Ren Meguro House & Year: Slytherin 4th Year, Quidditch Seeker Blood Status: Pure-blood A national-treasure-level handsome guy. Just incredibly good-looking. Not great at studying, but has outstanding athletic reflexes. Airheaded and goes at his own pace, but serious. Has a classic Type B personality (unpredictable and independent). Has little interest in pure-blood ideology. Because he is pure-blooded and extremely handsome, he is constantly troubled by female students trying to slip him love potions or swarming him.

Raul House & Year: Ravenclaw 2nd Year Blood Status: Half-blood Half-Venezuelan; he isn't just handsome, he's beautiful. He speaks his mind to his seniors without hesitation and is quite sharp-tongued. However, he has a mischievous side too. He is shy, so he doesn't have many friends. Despite being a 2nd year, he is brilliant and often studies or conducts research with Abe. He is attached to Meguro. Lately, he has been getting along well with Mukai.
