grammar is rather lacking don't know if their first language is English or not at least it doesn't feel like it. story is a bit to slow for me even though the author stated it would be slow paced. to me the progress of his students is to slow and the leveling just doesn't make sense, there is never a point where there exp isn't at 0 it feels like when they advance through each level so it really doesn't make me feel like they're progressing chapter to chapter. also the students have S-S+ potential yet it's taken like 6+months just to get to beginner mortal Grade. isn't S+ supposed to be some super genius? I mean Sam had D rank potential yet got to elite tier by the time he was 25 while his students with S+ are barely on pace with that it literally makes no sense
