Shōseki

is a citizen of Konohagakure amd the apprentice of tool maker Iō.

Personality
He is an apprentice of Iō, and is helping him in his tool-making job. He often complains about hard work. One time he mistakenly sold Gameru and Kusune two ninja tools Iō created: Tsuru-Kame and Dako, to increase their budget.

Appearance
Shōseki is a bespectacled boy with dull, black hair, dark eyes and a rather broad face. He dons a red, high-collared jacket over a blue kimono shirt along with a simple, brown sash around his waist, brown pants and sandals. He wears a pair of black gloves along with bandages on his arms and legs.

Abilities
Though not much was seen of his abilities he is seemingly proficient with the Generic Sealing Technique.

Konoha History Arc
In his début he was seen on fire, before Tenten pushed him out of the way, wanting to hear more about the weapons that Iō made. He later brought out Iō's latest invention to show the Konoha shinobi but was interrupted by intruders. After seeing their weapons that Gameru and Kusune were wielding, Shōseki apologised emphatically to Iō explaining that he had sold the weapons to the men, believing them to be simple prototypes. Later after Tenten had defeated the men with the Jidanda, Shōseki took the weapon from her and resealed it much to the kunoichi's dismay.

Trivia
