This manga really has some of the worst side characters. It sucks, its got a pretty okay MC (great representation of a healer, and he obviously has some backbone to him, but not nearly enough for my liking),
A handful of good side characters, such as Garm, and Kamiyu. That new healer getting trained by Tsutomu is okay too. Every single other character though? Complete dog shit. It's actually insane. Near unfathomable.
