Mairo

Mairo was an employee to the Tsukiyama family. During the battle between Matsumae and Hairu Ihei, he leaps between the fighters, tells Matsumae to take care of Shuu and takes a blow intended for Matsumae from T-Human. He is blown in half, but is still able to use the momentum to decapitate Ihei as his upper body falls to the ground. Assumed dead, Kijima starts up his quinque to challenge Matsumae, however, Mairo reveals he is still alive, berating kijima for underestimating his vitality, and impales Kijima through the shoulder with his kagune and distracts him long enough for Matsumae to finish the investigator off.
