This is the continuation of "Legend of Evening Street". Since the beginning of the "New World" era, the Demon World's Chrysis Empire has been destroyed by the power of the parallel world's Kamen Rider Black Sun, with only the remaining survivor Chrysis II narrowly escaping. The second generation, who was burdened with a blood feud, mistook Shadow Moon for the enemy who destroyed the empire due to erroneous intelligence and failed to recognize Black Sun's true identity. This led to a misplaced battle of revenge.
At the same time, the crisis has become more variable: a former armor captain in the Ares galaxy fell into madness due to his deep obsession and came with destructive power; there is also an armor warrior born from the outside world who has traveled across the heavens and challenged all armor warriors. At this moment, he is also involved in the dispute as a passer-by.
And Sawamasa, who was framed by Arasaka Company
In this battle, Ying Yue has lost the power of the Creation King, Zhao Yuan can no longer ascend, Ze Zheng's Feng Ling Yue Ying no longer exists, and Feng Yi has also lost the Longquan battle suit that can rival the gods. When all their former peak combat prowess fell, facing misplaced revenge, crazy powerful enemies, and mysterious passers-by, they had no choice but to put aside their past glory, use their mortal bodies and wills as blades, and find a way out of the desperate situation.
