This is a boomerang.
An manga is, at its core, just a piece of wood. A stick. A chip off the block of something far greater. And an isekai? Why, that's just a bent piece of wood.
But you carve that bent piece of wood just right, you toast it so its just edgy enough, and you polish the backside, and what you have is a bent stick you can hurl at somebody's face, and it's either gonna smack 'em good or come flying right back to you so you can whip it back at their face again.
This is a boomerang. Polished. Edgy, yet blunt. Sexy in all the right ways. It flies off to fuck-off land and comes right back with a zinger. Sometimes it hits the target. Usually, though, it comes whipping back at you from an unexpected angle and catches you in the nose instead.
