So I had this mental image of Fatgum meeting Toshinori pre-Kamino (maybe he needed to visit Might Tower?) and deciding that this guy needs to be FED. He might even find snacks for him that adhere to his dietary restrictions. Anyway, it naturally mutated into thinking how to expand on this with other heroes helping "ordinary civilian" Yagi.
i truly think fatgum is underrated. he's so encouraging and he definitely looks out for everyone. fatgum making sure everyone gets what they need!!
this isn't exactly what you're talking about, but the blog talked about a preparation au that's kind of similar if you wanna check it out!
