Anime debut: Naruto Shippuuden Episode #484
Light Novel debut: Sasuke Shinden: Book of Sunrise
Nowaki is a talented shinobi, having proven so by excelling in the Coliseum where wealthy collectors pit their ninja against each other. He is also skilled enough to briefly hold his own against Sasuke Uchiha.
Nowaki possessed the Typhoon Release kekkei genkai – a powerful variation of Wind Release. With it, he could easily conjure powerful winds to mow down or otherwise limit his enemy's field of vision. With effort, he could also use a much stronger variation of the technique, having shown to not only dwarf Sasuke's Complete Body — Susanoo but also being capable of briefly forcing it to the defensive. The storms Nowaki can create using his kekkei genkai are severe enough to cover an entire island.
