The official website for the anime adaptation of Level 5’s Megaton Musashi (Megaton-kyū Musashi) media project announced that the anime will premiere on October 1. Level 5 announced the project in 2016, and was initially planned to start in summer 2017. The project includes a TV anime, game, an Internet anime spinoff titled “After School,” a collaboration with Shueisha’s Weekly Shonen Jump magazine, and a toy partnership with Bandai.
The project’s updated cast includes Toshiki Masuda as Yamato Ichidaiji, Shunsuke Takeuchi as Ryugo Hijikata, Sōma Saitō as Teru Asami, Kōki Uchiyama as Reiji Amemiya, Sumire Morohoshi as Jun Kirishima, Megumi Han as Momoka Saotome, Ayumu Murase as Kota Akutagawa, and Yūki Kaji as Takumi Kindaichi.
Megaton Musashi’s story takes place after an invasion where 90 percent of humanity was wiped out. Three teenagers from a survivor shelter are chosen to pilot three machines that combine to form the Musashi robot. Each different medium in the project will tell the story from the different perspectives of each main character.
