80% less assholish discount Accelerator in a fantasy story featuring the mandatory pile of tropes: protagonist with actually overpowered/cheat skill, sudden and unreasonable banishment, dragons turning into girls/instant waifus and a future harem promised by the synopsis. Just missing slavery for a bingo, I guess.
Absolutely nothing new in this wish-fulfillment power fantasy story, but at least the art isn't completely garbage, I'll give it that. The male lead also has more fabulous hair than most forgettable and generic potato protagonists in this sub-genre. Maybe his relaxed attitude and being open to female companionship (he was engaged, after all), is also worth mentioning over the typically indecisive nice guy made out of cardboard with an allergy to girls mysteriously attracted to him.
The more pressing issue about the writing is that the protagonist is already happy and untouchable by danger... we can conclude he'll just continue living as normal somewhere else. What conflict is there to solve, when he doesn't care about banishment and nobody can threaten him? I know this is chapter 1, but this is also usually where the core goal/conflict is introduced. I see it's more important to introduce waifu #1 ASAP so now I know where this story's priorities are.
We could actually end it on page 57 and pretend it's a oneshot, rather than continue on as a series that just goes through the motions until a harem is there for readers to fawn over. But let's see if he'll actually get a main objective other than just live passively and react to events.
