Sword Art Online

[Ryllharu]

Traditional video game shotguns perhaps.

But if this game is meant to achieve some aspect of realism...as we're led to believe, they could use slugs or even buckshot and it would work fine. Real shotguns don't fire at 45° angle or dissipate their kinetic energy within 15 meters.

Kirito would theoretically be able to deflect/evaporate the slug as he has been the bullets, but the buckshot might prove more challenging.

He was doing a fine job at keeping bullets from doing anything but graze him, so he'd probably have no problem.

The things Sinon was doing this episode was far more egregious than anything Kirito did with his harem protagonist powah.

edit:
added a video showing their effectiveness. Would have liked to have found a shorter one, but it gets the idea across.
