She kinda redeems herself *spoiler* Marie is actually Leon's little sister from the other world (duh) and after going through many hardships in the commonwealth (due to her harem's shenanigans) she kicks out her troublesome harem for a while so that they can grow up and better themselves, especially when it comes to handling money.
She does get tricked into making a stupid bet that cost's Leon his ship but they get it back. Overall I liked Marie and thinks she's funny especially when she has to wrangle her dumb harem.
