Let me just incapacitate 200 people with one attack then.

Kidding lol. Don't even think Akuna could do that, too widescale for the Furihaba Ametsuchi to effect unless she spread her chakra out REALLY far. Still wouldn't have enough.

Anywho, I'll prolly make a post tomorrow since ima watch a movie with my girlfriend and then go to bed. Thanks for answering :)
