Rokuro

is a missing-nin.

Background
Rokuro had a bounty on him, and was captured by Anaguma and his partner.

Personality
Rokuro has no issue lying and manipulating to survive, even at the expense of others. He is also very perceptive, able to see through people's deceptions.

Appearance
Rokuro is a tall man of lean frame and pale complexion. He has green, straight hair with bangs hanging over the right side of his face. He has brown eyes with purple lining under them. He wears a purple, sleeveless shirt with high collar, bands around it, and grey pants, bandages on his forearms, and ankle-high sandals. Yatsume thought he smelled of blood.

Abilities
Giving the bounty on him and the various seals that were placed on him, Rokuro is implied to be very skilled and dangerous. He can produce a grey substance that can take various forms, including a wrist-mounted blade and tendrils to invade a person's body, killing them.

Labyrinth Game Arc
After being captured by Anaguma, he and Rokuro were taken from their Thunder Train and woke up in Ōga's maze. Anaguma warned those who asked against trusting Rokuro. He listened to Ōga's explanation of his experiments, and during the collapsing experiment, he held Anaguma with his legs when he was thrown off after his water threads gave out trying to hold the platform together. Rokuro was able to convince Kakesu to release his restraints by promising to save her, but he simply dropped Anaguma and ignored Kakesu's fall. When Boruto admonished him for sacrificing others, he made it clear he would sacrifice others to save himself.

While waiting for the next experiment, Rokuro deduced that the Kusa-nin with them was actually Ōga's subordinate, having suspected his triggering of the first experiment, and his wariness of the platform edges before the rules were explained. Rokuro infected him with his jutsu to force his confession, and he died asking for Ōga's help. Ōga was unbothered by it, and Rokuro chose a scroll, feeling that hesitation was pointless. In the dark room, Ōga provided with with candles that would kill them if they let their lights go out, and explained their rules. Unwilling to cooperate with the larger group, Rokuro went ahead, joined by Batta and Fugō. They reached the end and had to wait for more participants to take an elevator. The girl who exploited Shamo's crush on her arrived and attached herself to Rokuro. When the rest arrived, two of them filled the missing spots on the first elevator to go up. They realised that the candles wouldn't last the entire ascent, so Rokuro claimed the girl's and blew it out so his candle would last enough. After the second group arrive, having pooled their candles into one communal candle, Ōga declared the second experiment over.
