One of Ganma's elite forces (and second only to Shintaro, he claims), Arashiyama is a shy person whose greatest dream is just to make friends, which he fails to do because of his lack of confidence and bad "wisdom" from his former teacher Marker. Arashiyama especially wants to make friends with Shintaro, who was the first person to talk to him at the Ganma Academy, and the first person to offer to be his friend. However, Shintaro's offer to be his friend in the original series was born of desperation, when he needed the help of someone sufficiently strong to put up a fight against his uncle, Servis, and Shintaro typically prefers to ignore his existence entirely. Arashiyama is a highly proficient flame master, and ranks among the most powerful members of the Ganma army not related to the Blue Clan.
