Supana returns to his master Kyoka Edami to have her repair his Valvarusher, which was heavily damaged during his battles with the Three Dark Sisters. As he arrives in her laboratory, he becomes intrigued by the blueprints of a new weapon she is developing.

A giant snake suddenly appears from the sky and attacks people with its petrification rays. Houtaro transforms into Gotchard and confronts the snake, who speaks in an eerie voice.

"Are you Kamen Rider...?"

What is the true identity of the giant snake?

While Houtarou is serving New Years Food to Rinne and the others, he's wondering who is the Orange Gotchard that appeared during Christmas, and the sudden strengthening of the Malgam...

Suddenly, a Malgam appeared before Houtarou! Houtarou transformed into Gotchard, but he struggled against the empowered Malgam. As the Orange Gotchard appeared, he tells the shaken young man "As you are right now, you'll never defeat that Malgam."

A suprising development awaits Houtarou and co. as a person starts to move after Geryon's revival...

Houtaro and Rinne are disappointed in a world where not only the Alchemy Academy, but also their teacher Minato does not exist. The Moon Malgam then appears in front of the two and mocks Rinne where it takes her into the shadows.

"What should I do to become stronger and defeat the Moon Malgam?", asks a worried Houtaro.

Gotchard Daybreak then replies. "I will transport you to the past."

Just what is in Houtaro's past? What should he do there?
