Black Astrology, Kurogane's Oath

is the forty-sixth episode of Kamen Rider Gotchard.
==Synopsis==
People's memories come back and information spreads that Chemies are terrifying entities that turn humans into monsters. The town is in a state of panic, filled with people who fear Chemies and Malgams, and those who want to obtain Chemies and use them for evil purposes.
Then, Golem Gouriki appears before Houtaro and transforms into the Gorilla Malgam. The alchemists are accused of being the masterminds behind the series of disturbances. If nothing is done, the world will be in chaos... Supana makes a decision and takes action!
