@fractalwaves encountered Shadow Milk Cookie!
Takumi sees a very odd-looking school invader while in the courtyard. Good thing he has his Infuser- he quickly transforms and makes to slash the being with one swift motion. But in doing so, he squints- is that... a dessert?? Is he hallucinating..? He has been feeling weird lately...
"Woah-ho-ho, big guy! Watch where ya point that thing, it might hurt someone, hee hee!" Instead of being sliced in half, Shadow Milk's body shifts around the blade as it cuts through him as if he weren't there. Compared to Takumi, Shadow Milk Cookie is about the size of your average gingerbread man, and yet he moves and talks as if alive.
Shadow Milk Cookie himself doesn't know how he ended up here, but the magic he's so familiar with in Earthbread's makeup is long gone, meaning he is far, FAR from home. And yet, there is still a magical presence of a sort, a similar warmth to the flame flickering in the giant being's chest.
Is he one of the Witches? No, no that can't be right. There is magical power in the human before him, (How long has it been since he's seen a human? Eons? Millenia?) but it isn't the same magic that gives life to cookies like himself.
"Now before you get all stabby stab happy with that oversized toothpick of yours, you introduce yourself first. It's only manners, because you are being oh so rude to a guest like me, you know!"
