Kuraino Hidenka

Hidenka is the sister of Kasai and Akarui. She's the head of the family's niece, although she isn't a shinobi. Despite having the tainted blood that identifies the blood trait carried by the Kuraino, her powers never awoke, and she became a singer instead.

Hidenka and her lover are the Romeo and Juliet of Snow Village. Her lover, known as Metsubou, became a missing-nin after killing her grandfather, who was against their marriage. He was captured by the village, and she was told he would be put to death. The day before his execution, feeling herself unable to live without him even a single day, she killed herself; leaping from the bridge that seperated the two halves of the village, high on a mountain.

He escaped moments before his expected death, but hearing of his beloved's wretched fate, he allowed the ninja of the village to capture and kill him.

Depressing, no?
