Taira is a loving parent and husband, but describes himself as "a monster" at work. Though, he mistreats his subordinates and abuses loopholes in the law.

In the Island, he quickly establishes friendly relationships with everyone he meets, generally being uplifting and optimistic despite a string of injuries and extended periods of being left behind and neglected by his friends and allies.

[Spoiler: Taira is first seen when Ryouta bumps into him in a bush where Taira is doing his "business." Taira begs Ryouta to let him live. Afterwards, Taira explains to Ryouta what happened to him and the other participants before they landed on Btooom Island. Before Taira and Ryouta become partners, Ryouta asks Taira to reveal his BIM. Taira declines and explains that it's better for them not to show their trump cards.

Later on, he gets bitten and infected by a komodo dragon on his right leg while trying to protect Himiko who is unconscious. After being left behind by Ryouta several times while being injured and poisoned, he gives into his delusions of his family telling him to survive. He attacks Ryouta and Himiko who arrive at the abandoned communications tower. After failing to kill them, he runs away. While running away he falls and rolls down right nearby in front of 3 giant komodo dragons. He realizes that he only has one BIM left, and he takes his own life to pay for his sins.]
