Someone from the Devil May Cry series maybe. Dante and Vergil get love in other games like Capcom vs Marvel so maybe Trish (yellow haired demon creates by Mundus, supposedly reminds Dante of his mother or something similar. She ends up siding with Dante after realizing Mundus ain't shit tbh) or Lady? Lady is the human with the short brown hair, she rides a motorcycle and uses a rocket launcher among other weapons. She's a devil hunter and the daughter of Arkham, the evil dude who tried to harness the power of Sparda while betraying Vergil and fighting both him and Dante at the end of the third game.
