Had a headcanon I wanted to share. Technically this is for a "Modeus and Baul both live and are friends (Modeus) or rivals (Baul) with Dante" AU, but anyway.
-Modeus and Baul both let Patty style their hair. Modeus does it first, because Patty asks (Patty: "You just have so much hair! It's so long and pretty!"), and Baul follows his brother's example. They're both fond of Patty (Baul, grinning: "She's all frills and vinegar."), Baul is just more awkward about it because he's not used to being around kids. Its like having a tiny kitten follow him around, to him. Patty's something small and fragile and also a person and he doesn't really know how to act around human children. He tries to be nice to her, tho, in his own hesitant, fumbling way. Modeus is better with kids.
Anyway, Patty does their hair. Maybe Patty even manages to rope Dante into it, too. There's a lot of frilly ribbons and braids and probably at least one pair of pigtails. I think Modeus could probably teach Patty some other ways to braid long hair, too, since he has so much practice with his own hair.
I absolutely have no words. I just... I LOVE YOUR HEADCANON!
