Originally turned by the greater demonoid Valak to become a lesser demonoid, the woman that will later be known as Seir was reborn into a feral greater demonoid instead. The berserking new greater demonoid then turned against her creator and killed it, before slaughtering the rest of the lesser demons in the area, but leaving the humans alive.... more>>

In a turn of event, someone managed to subdue the newly born greater demonoid and even suppressed her demonoid cell, reverting the woman back to her human form. Introducing himself as the fabled 'Kamen Rider', the only person rumoured to be able to square up against a greater demonoid, the man explained to the woman that his assistant has crafted a belt that is both capable of suppressing and harnessing the power of the demonoid sleeping within her body.

The man promised to show the rope so that the woman could use her newly found power properly. In the process, the woman learned that the man was in fact, an otherworlder who came to this world for a specific task. After learning that the greater demonoids named themselves with the series of names that bear uncanny resemblance to the names mentioned in an old tale from his home world, the man named the woman 'Seir', citing that the Seir from the old tale was depicted as a beautiful horse rider; fitting as she'll become the rumoured 'kamen rider', replacing him as his main task in this world has now come to an end.

Thus begin the journey of Kamen Rider Seir to rid her world from the menace of the demonoids.

Kamen Riders. Heroes that have fought throughout space and time in the name of justice, love and peace. However, in another world, these stories are merely fiction, told on the television screens and through various other mediums of media, its legacy much greater than could ever be said.... more>>

In that other world, where the story of the masked hero of justice is one of fiction, one of the many people that tune into its episodes is Raiden Shoumi, a 20-year-old in Hikari Daigaku. As he lives his daily life, he dreams of another world, where he himself gets to fight against evil in the name of good. However, unbeknownst to him, and to the rest of the world, a wish upon a star brings forth a shadow that looms in the darkness, waiting to strike.

Mysterious rays of darkness target random individuals, morphing their dreams into wicked beasts. Raiden finds himself at the center of a monster attack, unable to do anything other than desperately cry for help as his life flashes before his eyes. However, a wish that brought forth evil has also brought forth justice...

Using a Driver, he transforms... and so the fight between good and evil transcends mediums and worlds alike... <<less
