Amaya Song

Aaron Song is Kamen Rider Scarab and the defender of Hizashi.

History
Aaron's father, Bae, disappeared mysteriously for a year when he was a teenager. When he was found, he babbled about an underground civilization, giant mole-badgers, gem weapons and being experimented on. Nobody believed him, and he became a conspiracy theorist. Aaron grew up hearing stories of the world he'd been imprisoned in, and getting bullied by other children because he believed them. When Aaron was twelve, Bae caused a massive street fight that led to the deaths of four people—according to him, one of the underground monsters had appeared and made him do it. This is exactly what happened; the bad guys tried an experimental mind control technique on him and just now triggered it. The courts chalked it up to paranoid delusions, and sent Bae to a psychiatric ward for the criminally insane.

Arata's mother Jin struggled to find work, and between various jobs and occasional handouts from Arata's distant grandparents, they got by. Arata became the homemaker, taking care of the house and his three younger siblings (twin girls and a boy) so his mother was free to work.

He developed an interest in mythology, particularly ancient Egypt, so when his old high school teacher offered him a part-time job helping him at the museum, he jumped at the chance.

Personality
Aaron is a low-energy, serious deadpan snarker who is generally independent by nature. He is very close to and protective of his family, and eventually Mizu, since all are people he can help and be helped by. In spite of what he did, Aaron thinks very highly of his father and insulting him is his berserk button.

Physical Appearance
Arata is Korean, with grey eyes and smooth black hair that brushes the nape of his neck. He dyes bits of it purple.

Trivia

 * Arata's backstory is based on the original version of a short-lived Sentai series called Reiki Sentai Yajuuranger.
