The Vermilion Mask

Everything about him is shrouded in mystery. The mask he can't remove. The past he can't unravel. And the very survival of the people who have chosen him as their leader. But what Hakuoro does know is this: he was gravely injured and left for dead in a forest. A kind young girl named Eluluu found him and nursed him back to health. He was welcomed into a barren land where strange creatures roam, an angry god seeks vengeance, an oppressive government slaughters the innocent, and a bloody war looms on the horizon. Will the masked hero liberate the people who saved him? Can he unlock the memories that elude him? Or will he remain a stranger even to himself?

In the era when samurai controlled Japan... The Masked Demons annihilated all but one member of the Shinsengumi, who had worked to maintain the peace and public order in Kyoto. Seven criminals are chosen as substitutes for the deceased Shinsengumi members, and they are led by Ichibanboshi, whose parents were also killed by the Masked Demons. He becomes a substitute for Commander Isami Kondo and goes after the Masked Demons with the other substitutes to avenge his parents' deaths. Former criminals rise up to restore peace and order as their crazy story begins! Now is the time to shine the brightest!

By finding a rare Action Kamen card, Shinnosuke Nohara and his family end up being chosen to go to a parallel world and help foil an alien invasion that is occurring over there.

The world is divided into two factions: humans and monsters called katawara. Despite being a katawara, Tama loves humans and vows to protect them from evil, even if it means fighting her own kind. Her brother Jinka, however, hates humans, despite mostly being one. The siblings are joined by a cowardly swordsman named Shinsuke, who wants to learn how to become strong. When the group uncovers a plot to experiment on humans and transform them into monsters, they vow to defeat whoever is behind it... Even if it means battling an entire army of warriors.
