Block 41: Part 2-Reiwa Generations Forever

Block 40: Part 1-An Unknown Evil (1日未知の悪 ;1-Nichi Michi no waru) is the 41sr episode of Jettacosta Sentai Himitsuranger''. ''As the title implies, it is the 2nd in a 3 part arc where Southern Cross tries to summon The End of the World as We Know It (or ITEOTWAWKI for short). This episode sees the final television apperance of Kamen Rider Zero-One, Kamen Rider Vuclan, and Kamen Rider Valkyrie as well as a false pre-series cameo by the then current rider Kamen Rider Harikēn. Like Tsukuyomi with the Zi-O trio, Izu doesn't retrun with the Zero-One riders.

Plot
Hurricane has found a forbidden cave and begins to track down the ancient septers with Emente's Help. On the road, they are stopped by a fast dinosaur-themed Kamen Rider before Kamen Rider Vulcan, Kamen Rider Valkaryie, and Kamen Rider Zero-One surround him. They ask the new hero who he is, but Woz steps out of the shadows: "from the fog of the darkest hour of the sentai and the rider rises the fast dinosaur Kamen Rider. Tremble before Kamen Rider Harikēn."
