If you ever wanted to read a story...
Of a human child raised in isolation by a being/beings with connections to death [Fantasy✔];
One where that child grows up to become exceptionally strong in battle [Action✔];
One where the MC sets off seeking answers about their non-human parental figure(s) [Adventure✔];
One where romance is not a focus, but there is a good friendship to find later down the line;
These titles may be for you.
The protagonist is male in Saihate no Paladin and female in Shinigami ni Sodaterareta Shoujo, but both stories remind me of the other.
