New:

(Discover Arc) is the old 1st arc the series has been rebooted, which is only still here to compare it to the rebooted chapters.

(Resistance Arc) is the new first Arc with overall better writing and has more of a serious tone.

This is a Shounen Isekai both genres play an important role.

(Lol I guess the Dimension stuff actually can be claasified as Isekai now that I think of it.)

Warning: this is indeed not an Harem OP mc type of Isekai story, so if you were looking for that, then there are plenty of other Isekai stories you can find with those requirements XD.

Without further ado lets get into the first chapter!
