well collecting skills is marginally more interesting than collection harems.
and a MC with zero interest in girls is actually more interesting in isekai, since none is going to write a proper respectful romance in the isekai genre, instead of some thinly veiled rape or magic dutch-wife
there's not a lot interesting about this work, but there's also nothing really offensive u'd find in most isekai trash, it's just bland, but isekai is usually worse than bland... so this is good, relatively speaking?
the slave thing ehh, at least author acknowledged it's supposed to be bad, probably just a throwaway line but whatever...
besides, since he "saved" all the other girls, they practically worship him already so whatever............
it'll probably turn into a harem sometime soonTM
@Temeraire it was that much already, if not worse since MD seems to have drama more often than batoto did, but likely batoto would have suffered the same dramas had it stayed alive anyway.
there's the screaming entitled teens, and the old meme of "batotoians" who love to trashtalk manga they dont like and still read it anyway. what else is missing?
@Kaarme ya it's prob a jMMO or mobage with kMMO rates, those are very common.
