Shuu Aoi (葵 終 Aoi Shū) is the son of Ren Aoi and Saki Aoi. He is one of the main protagonists in the film Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai.
Before his death and revived as with a strange power, Shuu was angry with his mother for breaking her promise to take him to the lighthouse. After being involved in a traffic accident where he was hit by a truck, Shuu was unable to meet with his mother at a lighthouse. His father joined the Badan Empire to find him alive, but apparently got himself brainwashed. Though he was supposed to be dead, Shuu discovered his power of his imagination to survive and finds out that Badan Empire is planning on using him as a vessel for reviving an army of monsters, including their leader to destroy the world. Aware of their evil plans, Shuu tries to escape from them, even his brainwashed father. Shuu's presence causes a fight to break out between both era Rider sides.
Shu's Imagination is even more potent than the ToQgers, allowing for Badan's plans to come to fruition. Although he almost got to the lighthouse, with the protection of the Heisei Riders however, he is somehow captured and being used to revived the Great Leader of Badan. After Badan's defeat and his father has finally broke free from Badan's control, Shu's body began to disappear, but not before he and his father finally reunite with his mother at the lighthouse, and telling them it wasn't her fault that he's dead.
Shuu Aoi is portrayed by Yuzu Aoki (青木 柚 Aoki Yuzu)
