is there more isekai/reincarnation/etc. series where the mc gets in the body of a completely irrelevant to the original story character
any genre. gl bl heteros no romance horror anything man
not the villainess, the relative of an mc, not a princess of a far kingdom, not the duke of the north, not the tortured character with 100 reasons to blow the planet up NOTHIN bro just a completely irrelevant nobody gaf total npc character
