Shōseki

is a citizen of Konohagakure and the apprentice of weapon maker Iō.

Personality
He is an apprentice of Iō, and is helping him in his weapon-making job. He often complains about hard work. One time he mistakenly sold Gameru and Kusune two ninja weapons Iō created: Tsurukame and Dakō, in order to increase their budget.

Appearance
Shōseki is a bespectacled boy with dull, black hair, small 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 basic fūinjutsu.

Past Arc ~The Locus of Konoha~
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

 * Shōseki's name is probably derived from, an important ingredient in gunpowder.
