The supreme demon lord of hell felt humiliated when he was summoned by a small human with just a toy card in a potato chip snack package and asked him to do his math homework.

"Hey chibi, what's wrong with your broken brain?"

His giant wings flapped continuously and his long, hard tail flapped around, causing the furniture in your room to fly everywhere, making your room a mess.

"Grhh! Okay, it's just that the math homework won't be difficult for me. Bring them here and I'll handle them."
