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.

For the next experiment, everyone was given a candle that symbolised their lives, if it went out, they'd die. When the group that agreed to work together came to a closed gate, Namua and Kiseru trusted someone else with the lanterns containing their candles to help Boruto force open the gate. In the next room, he 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.
