Labyrinth Game Arc
While on the Thunder Train, Namua and all other passengers slept and found themselves detained in a secluded room. Eventually, their captor, Ōga, revealed himself, explaining how he would put them through five experiments to test their ability to avoid death before being allowed to leave his maze. The first test involved escaping a brittle, collapsing platform on a chasm to a higher, safe ledge. He criticised Batta when the Wind Release she used to save herself further destabilised the platform, which she ignored. He helped Boruto take people up the ladder improvised by Kiseru, clearing the first experiment.

As the survivors grew restless and begin fighting amongst each other, Boruto insisted that team-work was their only chance to survive. Rokuro however pointed out that it would only work if everyone was really on the same side, having realised that the Kusa-nin was actually a spy for Ōga. As the man denied it, Rokuro then unleashed his technique on the man, demanding the Kusa-nin reveal himself. Fearing for his life, the man begged Ōga for help, proving Rokuro's suspicions to be true. Ōga appeared indifferently and watched as the man was killed. He then presented the survivors with the remaining tests. Rokuro chose the Light test. As everyone was sent to a dark room, Ōga presented them with each with a candle. He explained that everyone's candle at the start of the test was linked to their life and that if the candle went out, they would die.

Their journey led them through a watery pipeline. During which, Namua helped lift a gate blocking their path, trusting others to hold his candle. Once clearing the water stage, they found themselves in a desert-like incinerator. As the fans began blowing about dust that threatened to blow out the candles, half the group acted as a shield to the dust storm while the other half huddled to keep the candles lit. After managed to get past the fans, the final stage was for everyone to enter one of two elevators. Soon, it was realised that the elevators were going to slow for the candles to last. Kiseru reluctantly admitted that their only chance to survive was to sacrifice someone to take their candle as an extension to their own candle. However, Boruto remembered the exact wording of Ōga's rules and realised that they could all survive by unite their candles into one, extending the group's time and passing the test.
