This is the second installment of the Kage no Gundan series . All 26 episodes aired on FNS from 22:00 to 22:54 on Tuesdays from October 6, 1981 to March 30, 1982 .
Mr. Sanada was in 10 episodes of this show as Hayate Kozō. I have not been able to see the entire series yet, but have very much enjoyed what I have viewed!

The song is Silver Moon, an instrumental version of The Legend of the Ninja from Ninja in the Dragon’s Den
