overall it's not a bad story just a few bits that could be checked to make the reading smoother and constant gender change of the MC drag it down

none of the chapters after this one works but It might just be me

Luna for the win

no harem please

depends if it's Deadpool level they would heal in a day or 2 no problem anything lower I would say a week or 2 and double it if cauterised. but if it's magic or curse ability probably instantly but drains their strength and stamina like piccolo in DBZ

if you plan to have them using haki you should definitely increase the power levels of the enemy's or it won't be a good fight for alibasta,skypia and CP 9 p.s please don't make the MC op because some bleach powers are ridiculous

Nami

Thanks for chapters it's so hard to find a good mass effect novel I hope you continue to write. P. S please don't make the mc really op
