The translation needs to be revised, seems like machine for the most part, it can be understood but is not smooth.
The martial artist doesn't want him because she dislikes how his attacks look but mostly because she is left with nothing to do and fears being fired.
The holy knight really dislike how his magic looks and fears that the revival magic would be ugly too.
The hero doesn't want to lose the 2 beauties, hard to say if he is actually a good person or a calculative leech, he tried to left on good terms because of the MC revival magic.
It looks like MC still haven't full control of his powers and didn't unlock the revival magic, the thing they most want, so he was kicked out the party, this team is dumber than the usual, firing someone because they were too efficent, the hero was the one to decide so he could have kept him and razed every quest with ease when relaxing withthe girls, MC isn't really stupid for once, just a kid that doesn't knwo beter but have very mature moments.
Still better start than the story with the exiled dark mage that casted invisible debuffs and refused to show the effects to his party because they are humans from trying it once on 1 of them but after being fired got in the demon king army that well, fights humans.
