Futsu is a young light-skinned individual with short, dark brown hair that is kept in a small ponytail and is shaven on both sides. He has green pupil-less eyes. Futsu wears a dark yellow vest with a black tank top underneath and a pair of grey pants. He also wears a pair of white arm sleeves.
Futsu is undoubtedly a powerful shinobi as En Oyashiro claimed he was his strongest shinobi. He possesses the Boil Release kekkei genkai, which allows him to simultaneously utilise the water and fire nature transformations to create a corrosive mist that is capable of burning away anything it comes into contact with.
Sasuke Shinden: Book of Sunrise
Main articles: Sasuke Shinden (novel) and Sasuke Shinden (anime) En Oyashiro enters Futsu in the Coliseum to fight against Sasuke Uchiha, hoping that Futsu's victory will win ownership of Sasuke for him. Because he fought a boil-user in the past, Sasuke is able to easily defeat Futsu with Great Fireball Technique. Although this means that Sasuke can claim ownership of Futsu, he declines and instead asks only to meet with Oyashiro. During their conversation, Sasuke is convinced to try and help Futsu and the Coliseum's other competitors. He therefore asks fora rematch with Futsu, whose minor injuries have already been healed. When Sasuke defeats Futsu again, he grants him his freedom. In the novel, Sasuke asks Yamato to help Futsu and the other slaves he freed settle in Konoha; in the anime, the slaves are taken in by Kumo.
