Sendan

"I call in the name of Kasan Soukun! Sparkling Light and Black Darkness. With the two, annihilate all creation!"

- Hake's Attack Phrase

Sendan is the Kitsukami of Seireitou "Hyuga" Kawahira and the younger sister of Hake. The contract item she was given is a diamond ring that Seireitou gave to her that used to belong to his mother.

Overview
Sendan is first introduced along with her brother, Hake as the two Kitsukami who serve Seireitou. It was later shown that during Seireitou's life amongst the Konoha villagers, both Sendan and Hake served as Seireitou's Guardian angels, watching out for him should he find himself in a probmatic situation.

Personality
She seems strict and demanding, but appears so because she seems to have the wellbeing of her contractor and master at heart at all times. Only perfect service is good enough for "Seireitou-sama".
