Kaito Tenjo

Kaito Tenjo is a Numbers Hunter in Yu-Gi-Oh! ZEXAL and one of Yuma Tsukumo's rivals. He is actually a nice person, but when he duels he becomes quite ruthless. When his brother Haruto Tenjo fell sick, Dr. Faker told him that it was due to the "Number" holders and the Astral World. As a result Kaito became a Numbers Hunter. There is also a robot that accompanies Kaito which is known as Orbital 7.
