Ikenami left a will that the scripts would be true to his Onihei novels, and that he prohibited any episode written by a scriptwriter on his/her own storyline so that when all original Onihei stories were made into scripts, the serial should be ended. The final Onihei episodes is planned as two Onihei Hankachō Specials, with episode #149 "Asakusa Mikuriyagashi" (December 18, 2015) and the final #150 shot in the summer of 2016 for broadcast in two segments in 2016-'17.
