Amamiya Arma is third in command of the Arma Clan compared to Erzaria Arma and Mugen Arma. Like her older sister Erzaria, Amamiya doesn't have a much animosity toward the Satonaka Clan and instead is only interested in fighting them in order to prove her clan's superiority and for the chance to fight against other powerful shinigami.
Amamiya is a well-endowed young woman with long, dark brown hair, brown eyes and a well developed body figure. She can usually be seen wearing a pink and violet top with a golden star on the front and a golden "10" on the back that slightly exposes her belly. Amamiya also wears a pair of capri jeans as well as silver flipflops.
When entering battling she removes all of her clothing and wears nothing but pure white silk, covering only the most necessary parts of her, to prevent anyone from seeing too much, and a long white veil which surrounds her body. The trick of this silk is that it is actually one of her clan's weaponry an is extremely dense to prevent tearing.
Solid Veil: Amamiya fights using a large veil which also serves to defend her from her opponent's attacks. Producing her weapon to counter both Kujina's and Kenji's lightning manipulation abilities, Solid Veil is made of an extremly soft and flexible rubber material. However, she has lined the material with various pieces of thin metal in order to conduct the electricity utilized against her into lasers of spiritual energy and utilize it in her fighting style. In terms of fighting style, Amamiya is very swift, being able to dodge continuous attacks from the likes of Kyodaina Uzumaki, despite Kyodaina being a master of hand-to-hand combat. She can freely form the veil into various pieces of weaponry to pierce opponents or even use it to constrict them during combat allowing her to strike the killing blow. Amamiya primarily uses her veil to increase the range of her attacks, affording her a tremendous advantage over many melee-type fighters as well, She can freely form the veil in spear like shape to pierce opponents or use it to constrict them
