Personality
Namua is a very composed man, taking his time held captive calmly to instead meditate. He is also very compassionate, working to help others escape in their impending demise and likewise disgusted at other people's lack of compassion.

Appearance
Namua is a tall, solid man with a bald head and pale skin. He is dressed in a white shirt and pants with green robes. His shirt sleeve are secured by three green band each, a dark green sash around his waist, and his legs are bandaged with grey sandals.

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.
