Ninjutsu Technique Name: Blade of Wind Rank: A Element: Futon Range: Short to Medium range. Chakra Consumption: Medium Description: This technique is a pinpoint slashing strike, where the user emits chakra from their fingertips and materialises it into an invisible sword that assaults the enemy in a gust of wind and making a slicing sound. If the Sickle Weasel Technique can be regarded as a swarm of wind kunai, then this technique is an unavoidable longsword which leaves very deep slashes on the target's body.
