Background

Terai is a ninja of the Shimura Clan and a talented child from Danzō’s own clan. Unlike many Root recruits, he voluntarily applied for the ANBU Training Class because he believed its harsh environment would temper him into a stronger ninja. Danzō specifically instructed him to build a relationship with Chiba Lin Chuan, whose ability had attracted Danzō’s attention 31 35.

He ranked first in Root’s initial endurance trial and received the temporary designation Number Thirty-Four. His result placed him among the strongest candidates alongside Lin Chuan, Fū, and Torune 29 31.

Personality

Terai is sociable, upbeat, and eager to find excitement even under Root’s brutal conditions. He frequently tries to draw the reserved Lin Chuan into conversations, gossip, or dangerous investigations, and finds Lin Chuan’s single-minded focus on training boring 35.

He is also competitive and quick-tempered when challenged. When another recruit objects to his partnership with Lin Chuan, Terai immediately demands that the hidden speaker identify themselves 31. Despite his impulsiveness, he can recognize danger, accepts sound tactical advice, and works effectively within a team 35 47.

Terai is cautious about revealing his abilities. During the Forest of Death examination, he lies about selecting a Fire Release technique while concealing that he chose Wind Release: Vacuum Sphere; Lin Chuan sees through the lie, and the two treat their mutual deception with amusement rather than hostility 32.

Abilities & Skills

Trivia

• Lin Chuan mockingly calls him a “nepotism hire” because of his Shimura Clan background and connection to Danzō 34.
• Although he enjoys violence and excitement, Terai agrees that attacking unknown opponents without reconnaissance is unnecessarily dangerous 47.
