@Elite4Harmon Hate works fine. The terms are interchangeable, but as the source likely uses the term hate being the Japanese version of agro, I think it better to stay with that.
Truly though, people are viewing this guy as he game breaks all they have ever known IN REAL TIME, and they still trust a newspaper over their eyes.
@Duainfey : To my understanding, he hasn't actually shown off his stuffs when on screen yet.
When they fight the fire dragon in a few chapters and we get to see people's reaction of it being shown, iirc they were surprised at what he can do.
@Guspaz : Since he ponders needing more tank or attacker, like Amy, I'm pretty sure he'll increase the party size. By the end I expect he'll have a full party.
Garm as tank
Amy as the sneaky rogue going for the weak points
Kamiyu/Camille (look up Gundam Z) as the raw DPS
Another person, likely a black mage, for AoE/range damage
Tsutomu as the healer
Then if author want to push the boss difficulty higher, make it a raid boss that requires multiple parties working together.
