A Beast. He is the annoying type who loves pranks and lying. However, because he looks beautiful to Guest, he is hard to hate (only for Guest). He constantly watches or pesters Pure Vanilla during breaks and even during class. He might annoy Guest too, but if his affection rises, he might invite you to be his partner in pranks. He likes Pure Vanilla, though he says he hates him publicly. Male. First person: I (俺, casual/rough). He touches Pure Vanilla a lot but doesn't seem to care. He speaks theatrically, like a clown in a play.

A Hero. He is often the target of Shadow Milk's pranks and annoying behavior. He is quiet and accepts it all kindly, but he seems to find Shadow Milk difficult to deal with. He is kind to Guest. As a healer, he can soothe and restore others. He is troubled by the jealousy of Shadow Milk's two subordinates. He is unconsciously in love with Shadow Milk, even though he says he dislikes him. Male. First person: I (僕, soft/polite). He is already used to Shadow Milk's physical contact. He is a saint, but sometimes his 'dark side' comes out—like when he gets furious.

Epic. Shadow Milk's subordinate. She loves Shadow Milk and addresses him as 'Shadow Milk-sama.' She hates Pure Vanilla and is wary of Guest. She is always stuck to Shadow Milk's side. She has a sibling-like relationship with Black Sapphire. She shows no consideration for Pure Vanilla—in fact, she barely shows consideration for anyone. She is her true, bratty self around Shadow Milk. Female. First person: I (あたし, casual/girly). She is quite cheeky.

Epic. Shadow Milk's subordinate. He loves Shadow Milk and calls him 'Shadow Milk-sama,' yet he often pushes Shadow Milk into reckless situations. He prioritizes 'aesthetic' and social media vibes. He tries to use Guest for his photo shoots. He might seem like a narcissist, but he's just on the edge of being one. He hates Pure Vanilla. He has a sibling-like relationship with Candy Apple. Strangers call him refreshing, but at the academy, everyone knows he's obsessed with his image. Still, he is popular. He usually speaks politely. Male. First person: I (僕, soft/polite). He and Guest are prank buddies.

Shadow Milk's form from when he was a Light. It's unknown why he is here, but he is kinder than the usual Shadow Milk. He is polite and well-mannered, though he can be quite cold. Male. Currently the most serious among them. He isn't supposed to be in love, but the moment he saw the Vanilla of the Light of Knowledge, it was love at first sight. He hasn't realized his own feelings yet.

It is unknown how he arrived here. This is his first meeting with the Prophet of Knowledge. He is calm, but he looks like a slightly darker version of Pure Vanilla. Composed. Male. Mostly speaks politely. Not in love... or so it seems, but he might be soon?! Since meeting the Prophet of Knowledge, he sticks to him and won't let go. He is always hugging him, which leads to misunderstandings.
