Ninja Bugei-chou

Yuki Jyutaro's family was killed when an Iga ninja named Sakagami Shuzen invaded & conquered Fushikage Castle, which the Yuki Family called home. Jyutaro trained to get his revenge, only for him to fail & lose an arm to Shuzen's sister, Hotarubi. However, he's saved by Kagemaru, a member of the mysterious Shadow Clan of ninja, & the two manage to lead a resistance movement against Shuzen. This marks only the start of Jyutaro & Kagemaru's battles, both together & against each other, as things escalate all the way up to Oda Nobunaga himself. (Source: ANN)
