Why exactly would there be a problem if the hero lost? if it's every 10 years then both of the previous heroes are still around so why does it matter if this one loses?
@MostlyBlue https://www.mangaupdates.com/series.html?id=167008 Except It hasn't been. Unless you can actually show me it's been translated you might wanna stop making stuff up
@MostlyBlue I like how you conveniently left out that chapter 3 has not been translated at all but I mean go ahead and read the equivalent of picture books
