Ranjiro Kiyama (黄山 乱次郎, Kiyama Ranjiro), also known as Socho (ソーチョー, in English the President), is a character in the anime and manga series, Beyblade Burst Super Z. He is the younger brother of Rantaro Kiyama. He fights with his beyblade, Crash Ragnaruk 11Reach Wedge, although his first beyblade was his brother's Roktavor R2 Gravity Revolve. Ranjiro started Beyblade by the influence of his brother.
Ranjiro's face looks similar to his brother's, and has the same bandage on his cheek. Just like his brother, Ranjiro has a lollipop in his mouth. He wears a long white jacket with flame designs at the end. He has an orange shirt and pants that are half black and half red. His boots are white, and he has a belt with an R-shaped buckle. His most noticeable feature is his huge hair, which is blonde. His outfit is spontaneous, like his brother's.
- Ragnaruk Typhoon: Crash Ragnaruk uses its metal wings to generate upper force and create a twister that repels its opponents. The move is very similar to Rantaro's special move, Roktavor Zone.
Rantaro is Ranjiro’s older brother and was also one of the Beigoma Academy BeyClub’s founding members. The reason Ranjiro became a Blader was because he was inspired by his brother. In addition to this, Rantaro gave his old Beyblade, Raging Roktavor, to Ranjiro.
- Ranjiro possessed the very first hand-me-down Beyblade, which originally belonged to his older brother, Rantaro.
- Also, true to his form, Ranjiro plays the same role his brother played in the last two seasons.
- The Rebel Bey Club is similar to Ride Out.
