It All Started with Kamen Rider Tokio

He starts with a watch and a standard ID card, the only possessions in the real material world. In this world where the timeline is ridiculously chaotic, where a person can accidentally wipe out his entire existence, and where the risk factor is as high as 1000%, where should the young man Long Yu, who is obsessed with his identity, go? What kind of future will the "memories" that I occasionally fall into in drunken dreams witness? ! It's all about Kamen Rider's journey starting from King of Time! ! !
