Kamen Rider Wizard: The Promised Place
While Haruto is traveling abroad to look for a place to hide the Hope Ring, Kizaki, Rinko, and Nito break into a laboratory where artificial copies of the Phantom Carbuncle are being created. They are attacked by the Phantom Ogre who devours the copies and easily defeats the three Kamen Rider Mages, Mayu, Yuzuru, and Yamamoto before leaving. Ogre then goes after Haruto at a beach near Fortaleza, Brazil, in an attempt to force him into despair and bring forth his Phantom Wizardragon. After failing, the monster steals the Hope Ring from Haruto instead and flees.
After returning to Japan and reuniting with his friends, Haruto is attacked by Ogre once more, bringing with them a copy of Koyomi he created with the Hope Ring that is able to transform into the White Wizard in order to have Haruto choose between killing Koyomi or having her go in a rampage, possibly falling into despair. To prevent that, Nito knocks down Haruto and despite being warned about the consequences, wears a restored Beast Driver and renews his pact with Chimera, transforming into Kamen Rider Beast once again but he fails to defeat them as well. Back at the Antique Shop Omokagedō, Haruto regrets the fact that he did not dispose of the Hope Ring thanks to his attachment to Koyomi and is given a brand new Magic Ring crafted by Shunpei. Back at the fight, Kamen Rider Beast faces against Ogre while Kamen Rider Wizard confronts the White Wizard and, after Shunpei's ring fails to work, Wizard succeeds in dissuading Koyomi and returns the Hope Ring to normal. Ogre then forces himself into Haruto's Underworld in order to capture Wizardragon there and the Hope Ring reacts with Shunpei's ring, allowing Kamen Rider Wizard to enter his own Underworld, while Kamen Rider Beast confronts a trio of Carbuncle copies. Kamen Rider Beast defeats the copies while Haruto finishes Ogre and meets an image of Koyomi inside his Underworld, whom he entrusts with the Hope Ring before returning to the real world. Haruto and Nito celebrate their victory with their friends when a Crack appears and the Pitcher Plant Inhumanoid jumps from it, absorbing Nito before jumping back into the Crack, beside a red-colored Armored Rider resembling Gaim.
Kamen Rider Gaim: Sengoku Battle Royale! A competition is being held in Zawame City between Armored Riders Gaim, Ryugen, Baron, Kurokage, and Gridon with a batch of Lockseeds from DJ Sagara as a prize when a Crack opens amid the battle and the Pitcher Plant Inhumanoid appears from it, attacking Mai. Gaim, Ryugen, and Baron protect Mai and pursue the monster as it retreats through the Crack. The Riders arrive in an alternative reality where the inhabitants run away in fear from Gaim, mistaking him for someone else. Looking for answers, they join a battle with a Kamen Rider resembling OOO, while Takatora learns of the situation and follows after the other Armored Riders. Kaito breaks into a burning castle and meets Nobunaga, who entrusts him with a Core Medal before dying amid the flames, but he manages to save Ranmaru from the fire. Outside, the red Kamen Rider Gaim appears and defeats Kamen Rider OOO, before having him absorbed by the Pitcher Plant Inhumanoid. Kota and Mitsuzane flee the scene just to be later captured by an alternative Iyeasu Tokugawa, who reveals that in that reality each of the Heisei Riders are Bujin Riders serving a feudal warlord and fighting to unify the country but most of them have been defeated, including his own Bujin Wizard, by the red-colored Kamen Rider Bujin Gaim, who serves no one except for himself.
