Birth! The Third Rider is Grapes!

is the fourth episode of Kamen Rider Gaim. It features the debut of Mitsuzane Kureshima's first transformation into Kamen Rider Ryugen.
==Synopsis==
Kouta and Kaito work together to try to find Yuya, but they instead face off against an even more terrible enemy.
==Plot==
Finding themselves in Helhiem Forest, Kouta reveals to Kaito that he has been in the dimension before. With the knowledge that are unripen Lockseeds in the area, Kaito wanders off to get some before returning to his world. Kouta decides to use this time to find Yuya, but instead finds some researchers before getting into a fight with a terrible enemy: A white Armored Rider.
Defeating a Shika Inves, Armored Rider Gaim is overpowered by the white Armored Rider named Kamen Rider Zangetsu, convincing him that his Sengoku Driver was forbidden. The next day, after returning from Helhiem Forest with high class Lockseeds as bargaining chips, Kaito calls Team Raid Wild's Ryoji Hase and Team Invitto's Hideyasu Jonouchi to set up an alliance among their groups to take out Team Gaim.
At that time, Mai and Mitsuzane are called by Akira to check up on Kouta who tells them of his near death experience with the mysterious Armored Rider and that he is giving up being an Armored Rider. Taking the Sengoku Driver to Team Gaim's garage, Mai tells Mitsuzane of her experience in Helhiem Forest and that they can not rely on Kouta anymore for his own good.
But confident that Kouta will return, Mitsuzane meets up with Sid the following day and uses his status as a member of the Kureshima family to convince the dealer to provide him with a Sengoku Driver. When Team Invitto arrives to Team Gaim's stage with an Ichigo Lockseed, understanding the protecting others means risking his own well being, Mitsuzane reveals his new Sengoku Driver and uses the Budou Lockseed to transform into an Armored Rider.
