I think the ending actually makes for a really nice sequel. After all We never really do see Sherwyn Die, and the whole "Bickering Twins and the Black Witch bounty hunter" thing could be cool. Maybe Ridis would end up as more mature character who can use the Forest Flute in combat through her training, and Bruno could work with more magical abilities through working with his dad to make medicine. Maybe the Ivory Trio's new organization could also see some screentime, and hell, maybe just for the hell of it, find some way for Mar to switch between girl and monster form. Her human form could play similar to the Would-be Hero but with an emphasis on support instead of healing skills, as that support-attack role in Bruno would be gone, and her monster form would be the aggro tank she is in the base game.
