Yatsume

is one of Ōga's captives.

Personality
Yatsume is quite friendly, greeting Boruto after he saved Shamo from falling to his death. When Boruto leapt back down to the crumbling floor to rescue the others, Yatsume attempted to talk him out of it, worried about him dying. When Boruto nearly failed to save himself and Shamo, Yatsume climbed down the ladder and saved his life, showing her compassion despite them having just met each other. While willing to cooperate with Boruto, she does see the merit in Batta's more selfish approach, not dismissing it immediatelly.

Appearance
Yatsume is a young girl of average height and fair complexion with big, red eyes. Her hair is black and done up in an intricate style: She has ox horns on both sides with tight braids under them and two thick antennae hanging over her face. She wears a white bandanna, a light blue, clipped-shut jack, and black shorts.

Abilities
Yatsume is a kunoichi with quick reflexes and great agility, being able to rapidly climb down a ladder and grab Boruto's hand before he could fall to his death. She could hold Boruto's and Shamo's combined weight with just one hand. She has a keen sense of smell, smelling blood on Rokuro.

Labyrinth Game Arc
While on the Thunder Train, Yatsume and all other passengers slept and found themselves detained in a secluded room. When she asked Rokuro about himself, noticing he was bound by seals and cuffs, Anaguma warned her to stay away from him. Then, Ōga accessed the room, claiming they miraculously survived exposure to deadly gases unleashed on the train and were brought to this facility for quarantining, and decided to put them through five experiments to test the ability to avoid death before they can leave his maze. After the "Collapse" test was chosen, the group was teleported to atop of a stone floor floating above a massive chasm. There, she introduced herself to Boruto, and the two made their way to safety. Ōga explained that the floor was very brittle and would quickly crumble, meaning they would have to escape fast. Yatsume and most of the other ninja quickly escaped by jumping to safety. Yatsume however grew concerned when Boruto went back down to help other captives. When Boruto had to save Shamo and propelled himself back up, Yatsume reached to catch them. She stood by Boruto as he criticised Rokuro for sacrificing Anaguma and Kakesu to save himself.

While waiting for the next experiment, Yatsume saw value in both Boruto's and Batta's approach to the situation, asking Rokuro his opinion. When Ōga sent them on their next experiment, she was the first to discover the candles, and listened with the group to the rules of how the candles going out killed them, and what they had to do. When the group who decided to cooperate had to force open a gate which required both hands to open, Boruto trusted Yatsume with his candle while he helped open it. In the next room, she along the other shinobi helped protect the non-shinobi from a dust storm while they protected the entire group's candles. Near the end, they had to take a slow-moving elevator, and realised that their candles wouldn't last the entire ascent, Ōga intending them to steal each other's candles. Boruto exploited the exact wording of Ōga's rules to make one long candle with the remains of everyone else's, shared by all, so they all survived the ride, clearing the experiment.
