Kuranosuke Takeda

is a prince who once hired the Inuyasha gang for a demon extermination. Ever since he layed eyes on Sango six years back when the Prince's father had called on the services of Sango's family, he has been waiting for her to come back so he can tell her he loves her.

In the episode "Only You, Sango" he proposes to Sango, which makes Miroku incredibly jealous. Miroku confronts Sango and simply says "I wish you happiness." Kuranosuke eventually figures out that Sango loves Miroku, and wishes the best for her as well (after she refuses his proposal).

He tells Sango that if things ever go wrong with Miroku, he'll still be waiting. And he is still willing to do anything he can to help her.

in the Final Act he didnt attend Sango and Miroku's wedding.
