Kuranosuke Takeda

Kuranosuke 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.

In the episode "Aiming for Sango, Only You" he proposes to Sango, which makes Miroku incredibly jealous. Miroku confronts Sango and simply says "Be happy."

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.
