Ryuga Banjou may not be human… Everyone froze after hearing Misora's words spoken while fighting Rogue within the Pandora Tower. Rogue was speaking about using human experimentation on Ryuga’s girlfriend, Kasumi. Not only that but Blood Stalk was involved as well. Is Ryuga truly not a human? Meanwhile, the Kamen Riders alongside Sento burst within the Pandora Tower that is being controlled by Stalk. Just when that happens, something strange happens to Ryuga…
