after reading impression: Honestly, it gave me a laugh somehow. But honestly I'm way more interested in knowing how the punk is doing in the other world, I hope they get to do a spin-off or at least a bonus chapter about him getting to command a turf of farmers or something, maybe using his all mighty strength to flatten mountains so that people have more space to sow or maybe destroy old buildings about to fall so that others are not endangered.
the main story is fun but you can most definitely predict how it's going to turn, he is probably going to keep bumping into ladies to add the harem like a pokémon trainer capturing one after another and they're going to fight over who gets to pamper him more, up to the point where he has an army of the most powerful demons in this world. If it's predictable, you don't get to experience much surprising elements and that hinders the experience a little.
