So the author acknowledges internal damage. Which is surprising. I would've expected nothing but brute force and maybe even making a fake gun using telekinesis because gun is the ultimate isekai fantasy weapon.
But seriously, even his weak level telekinesis would be fatally deadly since the author has now confirmed that internal damage is a thing. Even at his base level 1, just move a bit of the brain matter inside an opponent and they would be instantaneously down for the count. Just wiggle the internal bone in the ear and they would lose balance due to vertigo. Just twist the eyeball and watch as they fall to their knees squirming, grasping their face and screaming.
Nevermind that we've entered a typical school setting, despite the first chapter suggesting a more world spanning adventure with an MC going full chuuni anti-hero from the shadows kind of deal. And with this, we know for sure there'll be a tournament arc as well.
Well, I don't really expect much creativity. Right now we've just had four chapters of reinforcing the concept that this is your standard slop. The only question is if this is going to become a harem or if he's going to be a single heroine man. And that's about it.
Also, as another example of just how horrendously powerful the weakest level of Telekinesis would be...
That first spell, just hearing about it makes me fear it's power.
