Rokuro

is a missing-nin.

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

Personality
A firm believer of survival of the fittest, Rokuro has no issue lying and manipulating to survive, even at the expense of others. At the same time, he is graceful in defeat, accepting his fate as the loser. 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, possessing the person to control their movements or kill 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 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.

Before the next experiment, Rokuro recognised Namua's tattoos as prison ones, prompting Namua to share his past. When the experiment began, and the ceiling began to descend upon them, he asked Shamo what he did, Shamo answering he tried turning on the lights. When the manage to reveal alcoves on the walls, Rokuro fought Kiseru for one of them, deflecting his Fire Release arrows, and taking one of the alcoves when he pointed out how Kiseru's arrows were spreading fire around everyone else. Most others collaborated to uncover a hidden space under the floor, which allowed everyone to survive the experiment.

The next experiment was the "Sum" test. Everyone was sent to a canyon with a tag marked from 1 to 8. The goal was to obtain tags with a total of at least 7 to exist the gate before time ran out. Rokuro's tag was "1". As he searched for more tags, he eventually found Batta and Fugō, taking their tags of "2" and "3". He then found Boruto, Yatsume, Shamo, and Namua. While Boruto offered to exchange his "6" for the 2 and 3 tags, Rokuro came to the conclusion that if everyone died, he would by default be freed, attacking them. He then possessed Namua with his technique, controlling his body to attack the others, insisting that Namua is in truth only following his deepest desires to survive. Boruto. As Boruto was able to reach Namua, he was able to resist the control. This prompted Rokuro to slash Namua in the back, to which Boruto defeated Rokuro with his Rasengan. Accepting that Boruto's will to survive was greater than his, Rokuro relinquished his tags. Boruto however decided to only take the "2" and "3" tags and give Rokuro his "6" as originally offered. Boruto declared he would not follow with Ōga's scheme. Rokuro then told Boruto that while he did take Batta and Fugō's tags from them, they were already dead when finding them, prompting everyone to conclude that Kiseru did it. Managing to return to his feet, Rokuro used his tags to enter the gate and clear the test.
