Ryo Ogami is a member of Sword of Logos who transforms into Kamen Rider Buster and one of the protagonists in Kamen Rider Saber.
He is portrayed by Yuki Ikushima.
In Ryo's youth, he was a childhood friend of Haruka Kiritani, who had saved him from a group of bullies as children. Years later, they attended Kagari High School together and stayed close.
One day on the way to school, Ryo witnessed and stopped students from a different school from bullying one of his classmates. Due to this, he ended up late to school and was scolded by Haruka at the front gate. Later, when he went to a vending machine for a can of soda, he saw and picked up the Genbu (Ryo mispronounced it as "Gentake") Shinwa Ridebook and pocketed hoping to return it later.
During class, he stopped a group of rowdy students from disrupting Kame-sensei's class, who later thanked him by buying him a can of soda, before witnessing the appearance of a Shimi. On Kame-sensei's request, Ryo visits the guidance councilor's to apologize in regards to his morning fight. After meeting up with Haruka, who had been worrying for Ryo, they are attacked by a group of Shimi who appeared in the classroom hallways. Ryo manages to keep Haruka away from the action as he leads the Shimi to the rooftops, attempting to fight off the monsters himself. Kame-sensei appears and asks for the Ridebook that Ryo had picked up earlier, transforming into Kamen Rider Buster in front of him.
Joining the Sword of Logos
While Kame-sensei trained him to inherit Dogouken Gekido, Ryo met Hayato Fukamiya for the first time.
Later when Ryo is initiated into the Northern Base as the new Buster, he is greeted by Sophia.
Ryo would later marry Haruka Kiritani and have a son named Sora.
Ryo was disappointed to discover that his friend Hayato had betrayed the group, and became even more distraught to learn that both his life and identity were stolen by Daichi Kamijo
Battling the Megiddo
He would later be turned against Touma Kamiyama by Reika Shindai along with Rintaro Shindo, Ren Akamichi, and Tetsuo Daishinji following the battle against Daichi. But later decided to rejoin Touma after his last duel against him.
