Well... at least someone commented on the fact the party has only one guy, but the thing is... I know this isn't a harem story, I truly think the author kinda was "forced" to leave it like that because well... isekai without harem isn't truly isekai, at least for those without taste.
But I would love at least one more guy on the team... preference one that isn't a thirsty coward leecher, I have no more patience for those types.
