Ryūichi Sanada

is the older of the two Sanada Brothers of Ishiyama High School. Both are second year students.

Appearance
Sanada has green spiky hair and green eyebrows to boot. He wears the traditional Ishiyama high male jacket with a blue shirt underneath. He also has a stitched up scar on his left cheek. Out of both brothers, he is shown to have the widest and more threatening looking grins and sneers, he also has a nasty habit of sticking out his tongue whenever he speaks, showing a single stud on his tongue.

Personality
Out of the two siblings, Ryuichi is shown to be much more eccentric than his brother, often yelling out of line and sneering menacingly.

Abilities
Though he shows little physical strength the fact he can haul a chainsaw proves how feared he was. Like his brother they use power tools against their opponents, whether or not they really used them against opponents is unknown.

On a side note, in the anime, the brothers own a motorcycle. Ryuichi is shown as the driver.

Techniques

 * Twin Headed-Dragon Sanada Bros. attack: Oddly enough, the brothers claim to have mastered their own "technique". Both charge at their opponent with Ryuji impaling them with his power drill and Ryuichi supposedly slashing them to bits with his chainsaw. It is not known whether or not this technique was actually used against oppenents is unknown.

Ryūji Sanada
With Ryuji being his brother, there can be no arguements that both are quite close to work as a delinquent team feared in Ishiyama high.

Trivia

 * Sanada is the first male character to have wielded a weapon against Oga.
 * He is also the second character to have wielded a weapon against Oga, the first being Hilda.
