Trend Gyao interviewed the president of Primastea, the producer of “Isshoni Training”. The president Nakagawa Munenari founded the company by a self-capital investment and wrote the scenario of the anime for himself. He wanted to do something so ridiculous that nobody dared to challenge.
According to the official profile, Nakagawa’s favorite anime are “Black Lagoon” and “Ichigo Mashimaro”.
