Kamui (Arcana Heart)

How Kamui joined the Tourney
Kamui is known as the Thousand Years Protector. Her Arcana keeps her in a state of eternal slumber, awaking whenever there is a crisis facing the human world. She relies on the Ministry of Elemental Affairs to give her an update on the current state of the world each time she awakes. With her trusty blade, Tamayorihime, Kamui is now on a mission to investigate the dimensional bend in the skies above Tokyo. Kamui's blade was specially crafted for her when she became the Thousand Years Protector. It has the ability to cut through ether (Elemental substance) without cutting the physical body. Her age is "unknown" but she appears to be 16. She remains in a state of perpetual slumber until awakened by her Arcana Anutpada (Time). It is a mysterious clock-like mechanism that has lasted since ancient times and has the ability to manipulate time and space at its whim.

Kamui sensed a danger in Echigo. When word got out that Kenshin was passing away, Kamui joined the sides against Kenshin's nephew Kagekatsu.
