Ryu Mukai

was the late friend of Nozomu Otani who transformed into the first .
==History==
Ryu Mukai wished to join Fenix in order to become a hero. However, before he could do so, the organization was dissolved following the battle against Giff and Hideo Akaishi. As a result, he instead agreed to participate in Masato Sotoumi's trial of an experimental new drug that parts of one's genes in order to strengthen the body. He travels to the designated meeting place, where five other volunteers are waiting. Sotoumi then arrives along with Minami, Hakim, and Tony. The doctor reveals to the participants that the "drug" is actually the Chimera Driver, and the test is to see who can become a Kamen Rider. A man named Shinta is the first to volunteer, and takes the Chimera Driver and Twin Chimera Vistamp from Minami. He attempts to transform, but instead experiences painful shocks. Tony then removes the Driver and gives it back to Minami before he and Hakim drag the man away. Sotoumi announces that the trial is cancelled, but Mukai asks for a chance as well. The doctor agrees, and Minami hands the Driver and Vistamp to Mukai, who successfully transforms into Kamen Rider Chimera. 
When the Otani family is attacked by Shinta, Mukai appears and pushes him away. He recognizes the man, who then transforms into a demon as a result of failing to use the Chimera Driver. Mukai briefly fends off the demon before transforming into Kamen Rider Chimera. In the ensuing fight, the demon is quickly destroyed by Chimera. After the battle, he goes to confront Soutomi about Shinta's transformation. Sotoumi apologizes and says that it shouldn't happen to him, but Mukai says that he won't work with him anymore and leaves with the Chimera Driver. 
Later, Mukai appears to fight off Tony and Hakim when the men attack the Otani family. Azuma then asks Mukai to hand over the Chimera Driver, leading him to realize that the attack was meant to lure him. Azuma attacks Mukai, and the two fight before Mukai transforms into Kamen Rider Chimera. Despite this, Azuma is still able to fight evenly with him and holds Chimera so that Minami can shoot him with a rifle, cancelling his transformation. Azuma takes the Chimera Driver from Mukai while the Twin Chimera Vistamp is picked up by Nozomu. After having Chic install one of Giff's eyes into the Chimera Driver, Azuma uses it to transform into Kamen Rider Daimon. Soon after, Mukai transforms into a strange demon as a side effect of using the Chimera Driver. In the resulting battle, Mukai is destroyed by Daimon, with the explosion also fatally injuring Kousei Otani and Kazumi Otani.

In terms of science, chimeras are organisms that contain multiples sets of DNA originating from either multiple zygotes fusing together or their tissue being transplanted onto each other.
