Simultaneous murders are going on, and Chase keeps popping up in surveillance tapes. While Kiriko and Shinnosuke believe in Chase's innocence, Go does not. But what is really going on?

Just as Shinnosuke had deduced, the bodies were of people the Roidmudes had copied in the past. Having avoided being defeated by Mashin Chaser after using a new Shift Car, Shinnosuke tries to see if there was anything left of his once righteous spirit. Also, Type Formula’s restrain on Shinnosuke’s body puts his life at serious risk. Go continues to insist on equating Roidmudes with evil and declares his intention of ending Chase as soon as he can. Meanwhile, the supposedly dead bodies stored at the morgue start crawling into the Special Investigation Unit's office.
