Ten years ago, a monster crashed to Earth and fell into a deep sleep. Now that monster, Grigio Raiden, has awakened! Z faces off against the monster, but something is wrong with Haruki... King Joe STORAGE Custom fights hard to follow the lackluster Z. How will this battle end?

The Artificial Life Form M1, created by Chief Mechanic Kojiro Inaba’s daughter Ruri, has malfunctioned and become gigantic!

Will Yoko be able to pull the trigger?!
