I think part of being an actual good person is accepting someone no matter what or who they are. A Hero should be happy to save anyone, no matter what. But I know that's not a totally popular opinion.
Personally, I think it's cool...

[But that's also her opinion, not Momo's. She doesn't need much time to think on that, though.]

I'm sure it won't be an issue, though. Yaomomo might be kinda surprised at the start, but you're nice and you're easy to talk to; you two'll get along fine.
Though you'll probably get something goofy like, "I see why you guys are friends" or something.
