鎧真伝サムライトルーパー

Musashi Houjou is one of the next-generation Samurai Troopers trained by the DST, the government body founded around Nasty Yagyu after five Troopers drove back the Youja realm's invasion of Japan thirty-five years ago. Promoted as idols, the new Troopers have never seen real combat. When a gate to the Youja realm opens and its soldiers pour into the human world, Musashi and his teammates are swept aside by a Youja warlord who hums old Showa-era songs as he fights. Then his own side shoots him down, and the figure inside the armor turns out to be a human boy, Gai. This series is the sequel to Ronin Warriors.
