仮面ライダー剣

Ten thousand years ago, a massive battle royale known as the Battle Fight was fought by fifty-two Undead, each representing a species fighting for dominance over all others. The winner was the Human Undead, known as Category Two of Hearts, giving dominion of the Earth to humanity. In the present day, archaeologists discover the sealed Undead, and accidentally set them free. Thus, a new Battle Fight begins.

Four years after an alternate ending to the series, in which Blade seals the Joker, the characters have moved on with their lives: Kenzaki is a garbage man, Mutsuki has graduated high school, and Kotarō has published a book about the Kamen Riders to great success. The Undead have been re-released, and a new trio of Kamen Riders—Glaive, Larc and Lance—have emerged from BOARD, now led by Tachibana. After recapturing two of the Category Aces, Kenzaki and Mutsuki join with the new Riders. When all the Undead are sealed once more, Glaive reveals himself to be the Albino Joker, a white version of the original Joker, and captures Kotarō's niece to obtain the ultimate power, sealing her in the Vanity Card. In order to free Amane from the card, Hajime is unsealed from the Joker Card and the four Riders are again united, intent on saving Amane and stopping the Albino Joker.

Many years after Kamen Rider Blade, the threat of the Undead rises once again and a new generation of Kamen Riders is recruited to fight them.

Takeshi Hongo is a promising young man with a passion for motorcycle racing. However, his dreams are suddenly ruined when he gets kidnapped by Shocker, the evil secret organization planning to dominate the world. After being remodeled into a cyborg, Takeshi escapes and swears to protect the world from the inhuman monsters.

A Trial-series cyborg pretends to be Kenzaki (Kamen Rider Blade), who quickly discovers the fraud and fights him. During their battle, the other Riders bicker humorously about which Blade is the fake, which constantly results in their attacking the real Kenzaki. As with all Hyper Battle Videos, this serves to explain in detail the Rider's various powers and abilities.

The Book of Ruin, which should have been sealed, is released along with the mysterious immortal swordsman, Bacht. Darkness overflows from the book, causing the real world and Wonder World to disappear. Touma Kamiyama, alongside members of the Sword of Logos, challenge Bacht to a decisive battle in order to stop this situation.
