AppearanceEditRyūji has green spiky hair and, unlike his brother, has brown eyebrows. He wears the traditional Ishiyama high male jacket with a red shirt underneath. He also has a scar on his right cheek, it can be noted it is slightly longer than his brothers. He also wears a pair of square rimmed glasses. Also, Ryūji is noticeably taller than his brother.
Out of the two siblings, Ryuji is shown to be slightly less eccentric than his brother.
Powers & AbilitiesEditHe shows little physical strength, but the fact he wielded a power drill against his opponents was probably enough to make him a feared adversary. Like his older brother they use power tools against their opponents, whether or not they really used them against opponents is unknown.
- Twin Headed-Dragon Sanada Bros. attack: Oddly enough, the brothers claim to have mastered their own "technique". Both charge at their opponent with Ryūji impaling them with his power drill and Ryūichi supposedly slashing them to bits with his chainsaw. Whether or not this technique was actually used against opponents is unknown.
With Ryuichi being his older brother, there can be no arguements that both are quite close to work as a delinquent team feared in Ishiyama high.
- "The Queen asked Oga out!": when Kunieda asks Oga "out".
- "Kyuu Kyuu!!!: what he and his brother often yell when excited.
