Kamen Rider Amazons
* Season 1 (Awakening)
- The world is filled by thousands of monsters named Amazonz, and the company of Nozama Pharmacy has hired a special team to hunt down and eliminate them. One day, the team were hunting down two Amazon riders, Amazon Riders Alpha and Omega, with their transformers being Jin and Haruka respectfully.

- Haruka eventually joined the team to hunt down the Amazonz. However, when they were trying to eliminate a group of Amazonz that were hiding inside a restaurant, Haruka eventually divided his opinion with the group when he found out that those Amazonz have no intention to harm humans. The restaurant has also changed Mamoru, one of the members in the team. He eventually started to have interests in eating human beings. After Jin and Haruka defeated Sigma, Nozama Pharmacy decided to launch a special plan named Tlaloc, a plan to kill all Amazonz. Mamoru was in a struggle during Tlaloc because he previously ate one of his friends, Kazuya Mizaki's arm. Haruka eventually rescued him and both of them escaped.

* Season 2 (Reincarnation)
- In the past, a massive spill occurred at the Amazonz experimental lab. Most of the survivors were destroyed, hot-blooded young men enjoyed hunting Amazonz and the experiment seemed to be drawing to an end. Far than ending, however, it was entering a completely new phase. The number of cases of ordinary people turning into Amazonz without warning was rising. The government formed a new extermination unit to assassinate people who had turned into Amazonz secretly and struggled to hide the truth.

- Chihiro/Kamen Rider Amazon Neo is a loner, a boy raised by Amazonz who hates them but must suppress his cannibalistic urges. One day he meets Iyu, an Amazon girl who transforms into Crow Amazon and vanquishes Amazon enemies with her awesome fighting power. Chihiro is amazed at his first glance of Iyu, because she’s the first human he’s met without thinking, “I want to eat her.” She’s the first opponent he’s ever wanted to get close to, but Chihiro is unaware of her story. Iyu is a “Sigma Type Amazonz” a biological weapon brought back to life after her parents turned Amazonz and killed her.
