The two teams then met with the villains and learned that they were brought together to be destroyed. Rintarou handed Mei the book he was carrying before emerging into the fight and she looked in disbelief. As the battle went on, Shoutarou was on nearby cliff drawing. The main antagonist approached him and asked if he found the hero he wanted to draw. Shoutarou said no and tore off all his drawings, causing all the heroes to disappear. Only Touma and Mei were left. Mei handed him the book, which revealed to be Saber book. They realized that they too are fictional and disappeared.
Touma woke up seeing him having meal with adult Luna and Kento, basically a world if Saber story didn’t happen and everyone was happy. He then found a book and proceeded to find out who Shoutarou actually was. Touma went to the past and talk with Ishinori Shoutarou as he just gave up drawing super heroes. He convinced Shoutarou not to give up and the two wrote a new book, Super Hero Senki.
Back to the present, with the Senki book and Shoutarou’s sketches, Ichigo and Akaranger were summoned. From them, 50/55 years of Rider/Sentai followed. Then classic roll calls happened and the big battle happened. Catch phrases and logoes from past series were featured along the fight. Kaito used Akibaranger gear (who proceeded to ask for his sign lol) and the monsters started saying death flags from Gundam series (?) then get defeated. Meanwhile, Revice appeared and fight. Touma and Shoutarou were confused because they didn’t create that guy. The villain got defeated and turned giant. Past Sentai mecha appeared, Riders rose Yohohoi’s ship and Rider kicked the giant monster along with Sentai mecha finisher.
The movie ended with Honjou Takeshi appeared, thanking Shoutarou for creating him. Shoutarou said he’s happy that even after he died, the heroes he created still fight on before going back to his world.
