Kamen Rider Blade: Kazuma Kanzaki

Kanzaki was scouted by BOARD as a candidate to become Kamen Rider Blade. His excellence in
intellect and skill earned him the spot. He is a kind and caring yet tough and resilient individual
who truly believes in fighting for justice as Blade. Beneath the tough exterior is a tragic past that
compels him to strive to help others. He admires Tachibana a lot and considers him a mentor. As
Kamen Rider Blade, he is a resilient fighter that utilizes his poweres well, though he has a long way
to go to achieve a high level of skill.

Kamen Rider Garren: Sakuya Tachibana

One of the original developers of the Rider System and the first one to be able to utilize a rouzer to
become Kamen Rider Garren. Experience and skill makes him a very powerful and formidable
Rider. Due to some dissatisfaction on how the riders have been utilized, Tachibana rebels and
kidnaps BOARD chairman Karasuma. He began to realize that he was degenerating, slowly
becoming an Undead, and weakening. It was his meeting with the Peacock Undead that turned it
around for him. First Peacock Undead made him more powerful and then, with the death of
Tachibana's girlfriend Sayoko. Peacock became his object of revenge. After Peacock's demise,
Tachibana gave up being a Rider for a while until the Leangle belt was changing hands. He realized
that he was needed as Garren and resumed fighting. He is now currently actively fighting the
Undead and trying to mentor the new Rider, Mutsuki.

Kamen Rider Chalice: Aikawa Hajime

Hajime is not human, but an artificial Undead created by BOARD a long time ago. He has since
strayed and went on his own way. He was taken in by a widow of a photographer whom he watched
die. The family warms up to him, with the daughter, Amane, adoring him like a big brother.
Unknown to many for some time was his secret as Kamen Rider Chalice, a very powerful Rider.
Unlike the other Riders, he does not depend on an external Rouzer to unleash his power. A bet
materializes on his waist where he would swipe his Ace card. Hajime cares not for humans, except
for his adopted family. He fights alone, though he has somewhat of a respect for Kenzaki, but are
at odds with Tachibana and Mutsuki.

Kamen Rider Leangle: Kamijou Mutsuki

He never knew what was in store for him when Spider Undead first met him. He was an unwitting
participant in an age old war. Mutsuki was selected by Spider Undead to carry his power once the
undead met it's demise and was turned into an Ace card, a card able to make a new Rider. At first
he was under the influence of the Spider Undead. Slowly he began to take control of his own
powers under the guidance of Sakuya Tachibana. Just when he was about to gain control over his
own powers, frustration being in the shadow of the other elder riders begin to allow for the Spider
take hold again.
