Naiki Takanashi

Naiki Takanashi is an older (before Otani Yoshitsugu) father-in-law of Yukimura Sanada. Little is known about his origins and achievements as he lived an unremarkable life.

Samurai Warriors
Taking cues from NHK's Sanada Maru drama, Naiki is made a Sanada retainer in Samurai Warriors: Spirit of Sanada. First appearing at Kawanakajima, he aids Masayuki in delivering supplies to the Takeda and later helps him gain gain prominence during the Tensho-Jingo conflict. He also instructs a young Yukimura to gather medicine in a futile attempt to save the ailing Katsuyori Takeda.

Naiki also participates in both defenses of Ueda Castle, bravely facing Naomasa Ii in the first battle and pursuing Hidetada Tokugawa at Someyadai during the second. Although he becomes an active supporter of Yukimura's last stand in Ōsaka, he survives the onslaught and outlives his son-in-law.
