"Sabimaru-Senpai is gone."

Houtarou laments his immaturity and weaknesses in the face of fleeting, yet endless suffering. How can he help Sabimaru? Just then, Houtarou is invited by Kajiki to call out a UFO whose sighting has recently become more frequent.

Houtarou and his friends find a possibility to rescue Sabimaru by befriending UFO-X. However, the Three Dark Sisters and Sabimaru with the Dreadriver appear before them! Equip yourself with the Number 10 Chemy and Change to Super Gotchard now, Houtarou Ichinose!

The raw power of Super Gotchard overwhelms Dread and gains an upper-hand, but Dread is capable of executing counterattacks, resulting in a back-and-forth battle.

Meanwhile, Lachesis approaches the daughter-father duo Sawa and Manabe. Rinne attempts to protect them but Atropos intervenes with her magical abilities.

"So you are powerless after all."

Rinne is robbed of her bodily freedom by the triumphant Atropos...?!

Supana summons Houtaro and the others, erases the Chemy Cards so that they cannot be re-sealed again, and takes all the Chemy Cards from Houtaro and the others. However, Kyoka and Lachesis appear and reveal Supana's true intentions in front of Houtaro and the others.

When Houtaro learns the horrifying truth about Supana, he approaches Supana with fury. "Why are you always like this?" Houtaro and Supana finally clash!
