  ## Gaim Gaiden: Kamen Rider Zangetsu/Kamen Rider Baron
  
  ### Kamen Rider Zangetsu
  
  Takatora Kureshima 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 Kota Kazuraba.
  
  Meanwhile, Yggdrasill's Kurokage Troopers are being assailed by an unknown Armored Rider. The caretaker formerly employed by the Kureshima family, Tōka Akatsuki, makes an appearance. Being raised by a strict father, Takatora's only support during his childhood years was Tōka. Both are very happy to meet again, but on a depressing note as the Kureshima brothers learn that their father had died. 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 Tōka and Takatora puts one and one together. Confronting Tōka while using the Watermelon Lockseed given by Ryoma Sengoku, he tells Tōka that he will continue to do what he believes in, even if he lays down his life for it. He defeats Tōka after he regains the Melon Energy Lockseed. However, he is unable to kill Tōka due to their past.
  
  Tōka retreats back to the abandoned orphanage, after being spared by Takatora and don't understand that why a good man like Takatora carries a name of Kureshima. Shortly, Tōka 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. After cleaning the Kureshima residents with Mitsuzane, Takatora start to think about Kota's word about saving humanity without sacrifices, and perhaps he may use one of Kota's heroic influence a bit.
  
  ### Kamen Rider Baron
  
  While Kaito Kumon hunted for the Overlords during his alliance with Ryoma Sengoku, a foreign prince named Shapool visits Zawame as part of an inspection. Shapool finds Kaito to be identical him, having the latter sedated so he can switch places with him. While Kota and the Beat Riders were flabbergasted in "Kaito" actually smiling before he takes Mai to Charmant, the real Kaito finds himself taken by a group led by Shapool's butler Alfred. Alfred then deduces Kaito's identity, contacting to Oren to take care of him. By the time Kaito finds Shapool, the two are attacked by Alfred who threatens to kill Shapool while transforming into Kamen Rider Tyrant. Kaito protects Shapool and learns of his story, as well as sharing his own story with the prince. After finding out that Alfred has taken Zack, Kaito goes after Alfred. As both were transformed and battled each other as Baron and Tyrant respectively, Tyrant unexpectedly corrupted by the Energy Lockseed possessing Helheim's manipulation and became an Overlord Inves.
  
  Yoko later came in and gives Kaito the Ringo Lockseed she took from Ryoma. Though warned that it could turn him into an Overlord, Kaito uses the Lockseed to fight back as Baron Ringo Arms and defeats Tyrant with the Cavaliend Rider Kick before destroying the Ringo Lockseed. In the end, Shapool writes a letter to thank Kaito for saving him from Alfred's threats and taking what Kaito has taught him, to believe in friends and to fight for what is right, before he leaves Zawame City for reuniting with his father. Kaito went to his parents' tomb at a cemetery, and later walks out as the flowers were left onto his parents' tomb. However, though he did not become an Overlord at that time, the event is still within Kaito's future.

  ## Gaim Gaiden: Kamen Rider Gridon vs. Kamen Rider Bravo
  
  The timeline takes place after the novel storyline of Kamen Rider Gaim and the stage-play Zangetsu -Gaim Gaiden-, and prior to Kamen Rider Revice: The Mystery.
  
  ### Episode 1
  
  Sometimes after Jonouchi becoming a star pâtissier succeeding Oren, he is overcame by an ego of his newfound popularity, much to Oren's dismay. Oren, who now retires to return as a mercenary is enlisted by Takatora to investigate the re-appearance of Helheim's fruits, suspecting the source coming from Jonouchi.
  
  On the next day, Oren learn from Jonouchi about a new source of fruit for a new cake, but ashamed of his student haven't researched about an unidentified fruit yet. While leaving, Oren is attacked by Armored Rider Gridon, who immediately left before Oren transform. Believing that Gridon is Jonouchi, Oren gears up, and sent a challenge message to Jonouchi. Jonouchi's secretary, Masako Suzuka does not want Jonouchi to waste time with Oren's challenge, but he accept it anyway, thinking he might be jealous of being surpassed by his student.
  
  Arriving at a port as what Oren asked Jonouchi to meet him there, Oren destroys Jonouchi's car and transform into Armored Rider Bravo to teach Jonouchi a lesson and re-correct the path of pâtissier he thought he abandoned it. However, the Helheim crack somehow appears behind Bravo and corrupt him into a mindless Bravo King Durian Arms. Thankfully, Jonouchi and Suzuka are saved by the same Armored Rider Gridon who attacked Oren. The said Armored Rider Gridon is revealed to be Takatora in disguise.
  
  ### Episode 2
  
  Jonouchi goes to find out why the other Gridon, a disguised Takatora shows up, telling Masako to stay behind. Once a mindless Bravo is distracted into attacking three innocent workers, Takatora reveals to Jonouchi why he persuaded Oren into hunting the latter, a scape goat who is unknowingly being used by someone into using Helheim's fruit for evil, relating to a new fruit Jonouchi found without constant research to develop Charmant's new fruit cakes. Because a now mindless Bravo needs to be stopped by Jonouchi's hand, Takatora gives the Gridon's Sengoku Driver he borrowed to persuade Jonouchi out of retirement from fighting one last time.
  
  While both Gridon and Bravo are fighting, Takatora found out that Masako had been manipulating Jonouchi into unknowingly using Helheim's fruits for Charmant's new fruit cake. As her cover is blown, Masako reveal herself as an Armored Rider who can control Helheim out of knowhere, Armored Rider Sylphi. Takatora immediately transform into Zangetsu Kachidoki Arms to prevent Slyphi furthering her evil plan.
  
  Just as Takatora experienced against Bravo King Durian Arms while as Gridon, Jonouchi is also unmatched against the Lockseed's power and had his Donguri Lockseed destroyed. When Sylphi's Helheim plants pierce into the warehouse and unknowingly knocks back Bravo, Jonouchi attempt to transform the passing by Helheim fruit into a Lockseed while his Driver still intact, but somehow no avail. At a brick of despair, Jonouchi was about to eat the fruit with no other option, but was prevented by the spirit of Hase, who transform the fruit into a Lychee Lockseed, allowing Gridon to achieve Lychee Arms and evenly matches King Durian's strength.
  
  Once Gridon freed Bravo from Sylphi's corruption and purifying King Durian's power, both student and master reconcile each other. Around the same time, Zangetsu eliminates Sylphi. Due to his master's sustain injury from the battle, Jonouchi carries him home until sunset.
