Kamen Rider Kuuga in Mysterious Resurrection

There are many unknown behaviors, such as memories being acquired by others, such as being unable to transform into the all-powerful form immediately after obtaining the Yamadam spirit stone (the requirements for transformation into the all-powerful form are very simple, as long as you have a fighting heart, you can transform). In the middle of a battle, you suddenly want to save human humor, and want to spread your own power of chakra. I don't know what it means, but wanting to be a hero is ridiculous!
