So I dropped this thing 30 chapters in, kept hoping against hope that they wouldn't assign such a good artist to such a shitty story, turns out they would, and they did. You can see my first impressions somewhere above.
The plot of the story is in the synopsis. Really, all of it is there. The brat was bullied, fell down the hole, popped up some time later as the LORD OF ASSPULL PRO MAX, and wants to kill all those who tried to kill him. It's just that. What's his ability? Asspull, where he has OP shits and 'waifus' delivered straight to him, with exactly zero effort needed on his side. The average paper tissue has more personality than the roster of 'waifus' presented in the story, which is such a shame because they LOOK GREAT. The characters all look amazing and it pisses me off even more because the art was so good it managed to hide the sheer shittiness of the story for a good while. It boils my blood to look at this shit, to see the amount of sheer talent displayed on the page, to be wasted like so. It's such a shame, really. Go find the artist's other works and read them. Don't waste your time on this trash.
