the two stories are completly different
'Shinda is an ecchi comedy
and patchwork hero is a dark fantasy
these two can't be compared
similar premise, dead hero, body gets taken over. Warrants the comparison enough for me. Where do you draw the line between the two series for being just "ecchi comedy" or "dark fantasy"? Even patchwork hero has ecchi scenes.
Regardless, I'm just saying out of personal enjoyment between the two, I also liked "yuusha ga shinda" but I just didn't find it as enjoyable as this, simple as.
