Arabaki has medium length hair. He wears a dark Japanese kimono, a light colored suit jacket, same colored suit pants, and black shoes.
As the arahitogami of Nihonkoku, he tried to do what was best for them, sending them to World Line N to be with Sudou Kaname and the others instead of dying with him on the island. He is shown to be calm, not panicking when Kaname grabbed him and pointed a gun at his head in anger. However, according to the Game Master, Arabaki wasn't able to do a good job as he had joined forces with governments and preferred to try to solve things by himself.
Guardian of the World Branch: As the guardian of an unknown world line, Arabaki has the ability to teleport people and give people sigils.
