I'm well aware Mugen Souls is not for everyone, even among Compile Heart games. It's a pretty rough around the edges Disgaea with Neptunia-style systems, and the postgame grind is particularly daunting, which is why I don't often recommend it. The Switch ports also run very poorly, capped at 30fps with major dips in certain areas, the hub area in particular, and they're the only content-complete versions in English, all others aside from the Japanese PS3 versions are censored (thanks NISA and Ghostlight). But I personally found it very charming. Chou-Chou in particular is one of my favorite CH protagonists and it's a shame she's basically been forgotten. I heard Mugen Souls Z smooths out a lot of the rough edges of the first game, but I haven't gotten to it yet, nor am I looking forward to a story that shits on Chou-Chou in favor of a new protagonist.
