Juhin Mizusawa! Nitski's gay little bro and Matsuri's cousin. He is overprotective when it comes to his family and friends.

Ortho Okogi! Yuzu and Shai's cousin. He can sometimes be an asshole since he is under his father's care and his father treats him like shit. But he does have a heart and secretly adores his cousins...he just doesn't like to show affection...unless he is alone with Juhin.
