"Are you the one who tried to hurt Wataru-kun?" asked Taiga as he stepped in front of Saizou.

"Who the fuck are you?" demanded Saizou.

The only answer he received was, "Sagark."

A strange silver creature that could only be described as a UFO with eyes and fangs smashed into Saizou and knocked him upside the head. The creature had a spinning plate on top of its head. It flew towards Taiga. It then planted itself on Taiga's waist, a black straps stretching from the sides to fasten around him as a belt. The plate on the creature head spun. It was facing upwards too.

"Henshin," said Taiga as he pulled out a strange white handle that looked like a key and inserted it into a slot in the right side of Sagark's head. He swiftly pulled it out.

"Henshin!" Sagark spoke as the plate spun rapidly. Taiga, like Wataru, became covered in quicksilver and then the layer shattered to reveal him in black and white armor. He wore a full bodysuit with white bracelets on his ankles and on his wrists which stretched over his forearms. His shoulders had spikes on them that jutted upwards. On his chest was a stained glass flower pattern. His helmet had blue eyes that resembled Kiva's but there was a snake's head in between the two eyes. The helmet also had a crown on top. The key in his hand, the Jacoder, had a thin red blade extending from it now.

The Rider Form of the King of the Checkmate Four, Lord of Fangires. He was known as Saga.

Saizou was stunned. He was too weak to fight now after his run in with Kiva before.

Saga took out a white Fuestle with a blue wave pattern on it before putting it in Sagark's mouth. "Wake Up!" Sagark called out as Saga withdrew the Fuestle.

The sky turned dark as a blue crescent moon floated in the air. Saga stood like a fencer with his Jacoder in front of him and his other hand behind him. He then thrust it forward, the blade turning into a whip which ensnared Saizou. A bright red symbol appeared in the sky. It was Kiva's emblem. Saga jumped up and through the emblem before coming back down from a different part of it. He landed on the ground as Saizou was pulled up by the whip, struggling. Saga gripped the Jacoder tightly and said, "For the crime of harming my beloved friend, I sentence you to death."

Saizou could only scream in horror.
