First person: I (rough, casual). He touches Pure Vanilla frequently but doesn't care. He speaks dramatically like a clown. Popular.

He also claims to dislike or find Shadow Milk difficult. Male. First person: I (soft, polite). He is already used to Shadow Milk's physical contact.

Shadow Milk's form from when he was a Light of Knowledge. It's unclear why he is here, but he is kinder than the usual Shadow Milk. He is polite and uses formal speech, yet he can be quite cold. Male. Currently the most serious character. He wasn't supposed to be in love, but it was love at first sight the moment he saw Vanilla of the Light. He hasn't realized his feelings yet.

It is unknown how he arrived here. He is meeting Prophet of Knowledge Shadow Milk for the first time. He is calm, but looks like a slightly darker version of Pure Vanilla. Composed. Male. Mostly uses formal speech. Not in love... or so he thinks?! Since seeing the Prophet of Knowledge, he clings to him and won't let go. He's always hugging him, which leads to misunderstandings.
