Ren Akiyama

is one of the main protagonists of Kamen Rider Ryuki who participates in the Rider Fight as for the sake of his comatose fiancee Eri Ogawa.
==History==
===TV Series===
He is a cold loner who fights constantly and is frequently unemployed. He received his Card Deck before the start of the series. He accepted Kanzaki's offer to join the Rider war to give his fiancée, Eri Ogawa, a full recovery, who has been in a mysterious coma ever since an encounter with Darkwing. Ren later contracted with Darkwing and became Kamen Rider Knight.

After Shinji Kido, he would still persist to fight any and all Riders. But the ordeal of his memory loss had him leave the Tea Atori to clear his head. Meeting Miyuki Tezuka, who reveals himself as Raia, while pointing out that though he accepted his fate as a Kamen Rider, Ren had doubts in his heart if he could actually take a life. He later inherited the Survive Shippu Card from Tezuka. Over time he eventually softened up and slowly came to return Shinji's constant offers of friendship. Throughout the series, they formed a somewhat of a rivalry, which Ren took more seriously than Shinji because of the Rider War.

Shiro eventually declares him as the last Rider. All the other Riders had died, but it was Shinji's death in Episode 49 that devastated him, as he had finally accepted Shinji as his best friend. Ironically enough, however, Shinji's dying words galvanized Ren into bringing the war to an end. Shiro Kanzaki brought him to fight the remaining Rider, Kamen Rider Odin. As Ren was about to lose, Shiro Kanzaki was tormented by his sister Yui Kanzaki's words, and self-destroyed Odin, thus making Ren the final Rider. The wish appeared, and Ren used it to save Eri's life as he had originally intended. Returning to the hospital where Eri laid, she wakes up to see Ren's engagement ring on her finger, and a loyal Ren, lying against the wall. Unbeknownst to her at the time, the battle with Odin had proved too much, and Ren died. After Shiro restored time to its proper course after Yui's death, Shinji (and also Ren) were revived with no memory of being Riders, thus they are unable to recognize each other in one of the final scenes of the series. It can also be noted that his fiancée, Eri still lives as she was put into a coma in the first place due to Darkwing.
