A collection of stories I've personally enjoyed about an OP MC in a variety of different situations. Usually an isekai or reincarnation.
Tends to avoid harem (or blatant romance) but there may be one or two. Trigger warnings will be added. A blatantly self-indulgent list in no particular order.
Part Two is here: https://www.mangago.me/home/mangalist/2214953/
yeah this is not really a list of isekais its just a list of strong female characters in medieval european-like settings fighting against one-dimensional female role archetypes.
they're kinda ranked but like not really don't trust me im disorganized in this list and in life help
