Fan Casting Akinobu Hayami / Yokai in Momakase

Jimmy Wong as Akinobu Hayami / Yokai: Akari's older brother and a manipulated masked terrorist who uses a neurotransmitter in his mask to control microbots throughout his crimes. He does not recognize his own sister, but nonetheless resents Akari and wrongly blames her for their father's "death." However, deep down, he still loves Akari and actually does not want to harm her. Akinobu is based on Robert Callahan from the animated film Big Hero 6 (2014) and is implied to be the same character as before. Masaki Okada portrays a young Akinobu.
