This whole "studying at all costs" gag is really irritating.
I'm gonna steal a quote I read somewhere back when this series was still in its early days:
"This guy must be the dumbest guy in the world to study all day and still seemingly making no visible progress"
dude is pretty fucking dumb. spends literally all his time studying, neglecting essentially every other part of his life except family work, and still has pretty shitty grades. determination is all well and good, but he's just got zero potential. amano is unironically and unsarcastically too good for him
also, jesus christ author can you not come up with ANY other gags?
i tried to stick with it, but i'm sick of hanging on for the sake of hanging on. goodbye, token story as vehicle for butts
For those of you wondering at home, Manabu's visual acuity ratio of 0.01 is the equivalent of 20/2000. In other words, to say he's as blind as a bat would be an insult to bats.
