When his fighting capabilities were revealed I was dumbfounded because it was way too fast, no beating around the bush, without further ado, he was so fucking strong that he even easily left his gears. lmao
Seriously, I even thought that it was a comedy-gag manga lol. I think the title should be "I thought I was a Healer, is, in fact, a gag Hero".
I think Cleric, Crusader, Paladin or Guardian would be suitable based on his capabilities not just a Healer.
Btw, if he was that strong he should just joined as damage dealer not a friggin' healer.
