Kamen Rider Gaim Gaiden 1

The first twin set of Kamen Rider Gaim Gaiden (仮面ライダー鎧武 (ガイム) 外伝), a series of V-Cinema (direct-to-video) releases that each serve as a spin-off of a Kamen Rider from Kamen Rider Gaim, featuring unseen stories which took place during the show.

After the success on the first twin set and an online poll for those who bought the two films, a Gaim Gaiden 2 was revealed by the official Twitter account on May 5, 2015.

Plot
The first two films focus on the characters of Takatora Kureshima (Kamen Rider Zangetsu) and Kaito Kumon (Kamen Rider Baron) respectively, along with the appearance of two new villain riders, Kamen Rider Idunn and Kamen Rider Tyrant and a limited V-Cinema original DX Forbidden Ringo Lockseed and Idunn Faceplate. Separately, an accompanying CD was also released simultaneously, featuring two insert songs, Unperfected World by Yutaka Kobayashi and Lights of My Wish by Yuumi Shida. The film and the CD were released on April 22, 2015.

Kamen Rider Zangetsu


Takatora Kurshima is continuing preparations of Project Ark, which would mean the salvation of humanity at the cost of numerous lives. Takatora’s resolve in seeing this through is put in question after a conversation with Kouta Kazuraba.

Meanwhile, Yggdrasill’s Kurokage Troopers are being assailed by an unknown Armored Rider. The caretaker formerly employed by the Kureshima family, Touka Akatsuki, makes an appearance. Being raised by a strict father, Takatora’s only support during his childhood years was Akatsuki. Both are very happy to meet again, but on a depressing note as the Kureshima brothers learn that their father had passed away. However, the mysterious attacker, using the Ringo Lockseed, leaves Sid injured and Yoko to be on the defensive. The mysterious Rider sets their sights on Mitsuzane Kureshima and Takatora loses his Melon Energy Lockseed as a result. While searching for clues, he uncovers the truth of his father's past and learns that the people at Zawame Child Care Facility were subjugated to lethal experiments to allow passage into Helheim. Among the list of people in the orphanage is Touka and Takatora puts one and one together. Confronting Touka while using the Watermelon Lockseed given by Ryoma Sengoku, he tells Touka that he will continue to do what he believes in, even if he lays down his life for it. He defeats Touka after he regains the Melon Energy Lockseed. However, he is unable to kill Touka due to their past.

Touka retreats back to the abandoned orphanage, but experiences the side effects of the Ringo Lockseed and learns that Ryoma Sengoku was also raised at the orphanage before being killed by Ryoma, who promptly retakes the Ringo Lockseed.

Kamen Rider Baron


Kaito Kumon continues his search for the Over Lords after being egged on by Ryoma Sengoku. The objective: become stronger. Meanwhile, the heir of a foreign country, Shapool, visits Zawame as part of an inspection, and Kaito discovers this Shapool person is identical to him. Eager for some freedom, Shapool finds Kaito, sedates him and steals his clothes which then he appears before the Beat Riders posing as Kaito. Kouta and the others cannot believe their eyes when they see who they believe to be Kaito dancing with a smile on his face. Shapool then takes Mai to Charmant, where they eat one of the cakes Shapool has baked. Meanwhile, Kaito comes round to find out that a group led by Shapool’s butler Alfred had been looking for Shapool. Being identical, Kaito is mistaken for Shapool and taken by the group. Alfred then deduces Kaito's identity and has found out of Shapool's location, where he contacts Oren to take care of him. Kaito and Shapool encounter each other again, where then Alfred has found them and threatens to kill Shapool. Kaito protects him and learns of Shapool's story, as well as sharing his own story with Shapool. After finding out that Alfred has taken Zack, Kaito goes after Alfred.
