4D Isekai, bring the fight against the hero before he reincarnates. It'd probably be interesting even without the yandere princess, but I guess there's gotta be a point of repeated conflict beyond just fate.
Okay, i've read it all with some degree of attention and quite enjoyed author taking jab at popular c, j and arpg mechanics. Curvy female bodies are still main point of interest here though, but that's okay. If i want something similar with a little more substance (sic), i can always go back to Tsugumomo.
that'd be too predictable but idk, maybe he'll work for the human at first due to some circumstance before (i hope) turning against them or something after whatever forced him to work for them are resolved
