Nigai

Nigai (ニガイ, Nigai) was a Kumogakure shinobi.

While on a covert mission to steal a kinjutsu from the Sugi Village, he, A, and Karai were set upon by the mercenary Nokizaru Group who had been hired to retrieve the scroll. Though initially telling his comrades to ignore the taunts of the group, he falls prey to it when they chide the Raikage for running away. Turning to face his opponents he uses a technique and immediately swelled to giant proportions and then exploded.
