Human Turned Demon? Armor Up, I Don't Have Time to Explain!

[Armored heroes + Kamen Rider + secret realms + merging worlds + making up for regrets + crossover + invincible] Secret realms descend upon Blue Star, drawing countless victims inside. Each secret realm contains different timelines from different tokusatsu worlds. Nether Demons, Orphnochs, Gurongi, Worms... When humans turn into monsters under the influence of the secret realms, are they demons or still human? Duan Muyan, who arrived with a System, doesn't care about any of that. He only knows that those who hurt others will be hurt in turn, and those who kill will be killed. “So what if they're demons? Does that mean they deserve to die?” Duan Muyan: If you don't die, do you expect me to die? “Demons are people too. Why can't they be given a chance?” Duan Muyan: I can't be bothered to explain it to you. You're not worthy of hearing it! The worlds gradually merge. When the final bosses from each world appear on Blue Star, A figure stands proudly beneath the shining sun. “I am the Heavenly Dao, and the Heavenly Dao is me.” “Emperor Armor, combine!”
