Takeshi Kotobuki
Takeshi Kotobuki is an Ajin and was also Kaito's partner in jail. Takeshi escaped the jail facility on August 6 but returned 2 days later of his own volition. He was taken into questioning for a month in solitary confinement. The questioning, however, was proven to have no effect as he insisted on his ignorance, saying he was "outside by the time he noticed it." His IBM is also the only seen Black Ghost with wings.
