Arcana Heart/Kamui Tokinomiya

Kamui Tokinomiya (朱鷺宮 神依) is known as the Thousand Years Protector. Her Arcana stays 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 while Konoha aids her.

Kamuji’s blade, Tamayorihime, was specially crafted for her when she became the Thousand Years Protector. It has the ability to cut through ether (Elemental substance) without scratching the physical body. The blade will allow none but Kamui to draw it from its scabbard. Her ability to wield such a weapon is proof that she is worthy to be the thousand Years Protector. Kamui is also obsessed with anything cute and cuddly. Rumor has it that she has a collection of stuffed animals, but she does not like revealing this to other people.

Kamui is always confused if it's something to do with anything modern.
