24x27 - Kamen Rider

Kouta is knocked unconscious by Ryugen's backhanded attack, and Baron fights Ryugen for acting so cowardly. Meanwhile, Takatora mulls over the idea of having to cull the Earth's population down to only one billion people through the use of the Sengoku Drivers, remembering back to the days of first developing them, unaware that even then Ryoma was conspiring against him. When Kouta regains consciousness, he explores Helheim Forest once more, only to be approached by someone unexpected.
