Houtarou continues his quest to befriend all the Chemies as he meets a Chemy known as Apparebushido, and is given his card by Minato.

A new Malgam appears and Houtarou attempts to fight it using Apparebushido, but it defies orders and causes Houtarou to be defeated.

"Just how can I get Apparebushido to open up to me?" Houtarou asks himself as he begins to secretly train. Just then, he is approached by alchemist named Spanner Kurogane, who demands the Gotchardriver!

Houtarou can't help but exclaim in admiration at Valvarad's powerful might. However, Spanner says that he didn't acknowledge Houtarou as a Kamen Rider and leaves.

Houtarou and Rinne, who continue their search for Chemies, come face to face with the Three Dark Sisters, Atropos, Clotho and Lachesis. Lachesis then absorbs a Chemy and transforms into Malgam. Houtarou transforms into Gotchard, but immediately after that, they are sent to a huge, different space!

Kajiki is depressed after being cold-shouldered by Hijiri, but is beginning to remember the memories that have been erased by Minato. Houtaro suggests to Minato that he revive all of Kajiki's memories for Kajiki and Hijiri's sake, but...

Meanwhile, the Dark King Gaelijah had begun a new course of action using Clotho. And that Malgam is in front of Houtaro and Rinne!?
