your character makes mine a meal. What's on the menu and does anyone get fatally incapacitated

Probably a simple meal

And safe to eat

Ayumu would probably bring Bishamon some high quality, old fashioned Japanese cuisine as an offering!

Eggs! Hard boiled eggs. Cause that's probably the only thing Hisui Maxwell can cook apart from instant noodles.

Maybe Ron, too, since she's friends with his shinki

Alice : they will greatly appreciate this offering!

hiroc : you can make him an omelette and he'd be happy

hisuimaxwell : we welcome your eggs ouo

Well, if Hakkai's not bringing by cakes for the kid shinki, he'd probably cook her a fancy meal, because it's fun to stretch his culinary skills sometimes. Likely Chinese, since that's most of his cooking repertoire.

And lucky for him, she comes from China!

A perfect match!

mackerel.

It's the thought that counts, Haruka-kun.
