Anime: My Instant Death Ability Is So Overpowered

Instant Death anime is pretty much all out our overpowered protagonist killing anything and everything that gets in his way. Sorta like One Punch Man, except, our guy doesn’t even have to punch.

All he has to do is think for them to be dead.

And you’d think at least the final boss of the anime would put up a good fight, but no. Our mc casually disposes her off without even giving her a chance.

Absolutely disrespectful.
