Daisuke Takamine/Part I-II

Part One
Daisuke is mentioned many times, from the Chūnin Exams Arc until his official appearance. He's referred to as "Sennin-sama" by Akihiro, Nakuka's wolverine. It is found out Daisuke fought Orochimaru at one point.

Sasuke Recovery Mission
Daisuke makes his debut after Sasuke Uchiha almost kills Nakuka with his chidori. Nakuka and Akihiro are bound by blood and tears, making it so Akihiro will die of a broken heart if Nakuka perishes. After finding out Orochimaru is still alive, and that Sasuke went specifically to said snake, he and Tamotsu Ōtsutsuki send one of their young spies to keep eye and word of the boy who almost killed Nakuka. This spy goes by the name of Kuchibashi.
