Takemoto Yasuto

He was elected in the second round of the foot race to be in the fifth lane. Once the game starts, Amaya grabs him so that he can know whether the answer to their question is true or false, therefore he throws him through the "false" door. It turns out that the answer was true, so Takemoto dies.

He was one of the five survivors from cube 70, along with Hirao Keiichi, Kita Eikichi, Tsujiuchi Maiko and Obihiro  Sonoko.
