Kouta tries to prove that he has not changed, despite all Kaito has seen in Helheim, and helps the others clear Zawame of Inves. However, Mitsuzane and Ryoma discover that Mai, who has been taken ill, is now the host of the Golden Fruit, and wonders why Rosyuo has placed it in her.
- Deadly Upgrade: The Yomotsuheguri Lockseed possesses power to rival Kiwami Arms, at the cost of its users Life Force.
- Obviously Evil: Ryugen Yomi. Instead of the usual zipper effect, the armor descends from a portal made of ominous clouds, with red lightning popping around it. When it attaches, it looks like red and black flames rise from the user instead of the normal energy and fruit juice effects that all the other Riders and forms get. The voice of the Driver is much deeper. Not to mention it's named after the fruit of the underworld, and the transformation announcement is chanting the name of the land of the dead. As one sub group renders it: Hell Fruit Arms! Realm of the Dead! Hell! Hell! Hell! It's repeated, just in case you didn't get the message the first time. And that's just the Transformation Sequence; once it's fully formed, it looks like a fusion of Ryugen's two main forms, except for the repaint: it's Red and Black and Evil All Over. Reeeeeeeal subtle, Professor Ryoma. (Of course, it is a hundred percent in character for him to go out of his way to make a crazy powerful but dangerous suit that could kill the user look and sound Obviously Evil just for funsies.)
- Wham Line: Sagara: Actually, let's go with the name you yourselves gave us. In which case, our name...is Helheim.
