Seeing Yusuke Onodera get up, he looked at them and said, "It's a long story, but the most important thing right now is to stop them from fighting!"
Thus, the alternate Kamen Rider Kuuga remembered his identity. He transformed into Kuuga, preparing to follow Raven's earlier example and forcibly intervene.
Suddenly, there were two Kuuga in the field: one transformed by Decade, and the other, the Yusuke Onodera version.
Seeing this unfold, Raven had an impromptu idea. He retreated to an inconspicuous spot, retrieved the Dark Decade Driver from the system space, and prepared for his first transformation with it.
"Henshin."
He inserted the card, and the transformation sound began.
"KAMEN RIDE!"
"KUUGA!"
He immediately pulled out the basic Kuuga card and transformed into Kamen Rider Kuuga.
On the other side, Yusuke, after transforming, attempted to forcefully stop the fight. Instead, he was struck again by the attacks of Decade and Kiva, tumbling a few times on the ground. He then leaped high above the three of them and kicked them consecutively.
"Another Kuuga!" Natsumi in the distance was truly shocked. Suddenly, three Kuuga were on the scene. She was completely bewildered.
"Raven-san, what exactly is going on now?" Natsumi instinctively turned to look, only to find Raven's figure had disappeared.
"Who are you?" Tsukasa immediately noticed the Kuuga Raven had transformed into; the belt looked similar to his own.
To maintain an air of mystery, Raven did not answer directly. Instead, he made an extremely mocking gesture toward the trio.
"Damn you!" Kiva was the first to lose patience, charging at Raven with his sword.
He was instantly defeated, however, having his weapon taken away bare-handed before being kicked to the ground. After Raven gripped the sword, it automatically transformed into Kuuga's exclusive weapon the next second. Raven then charged at Decade and Yusuke's Kuuga.
"So strong!"
Yusuke, the only genuine Kuuga in the field, was instantly overwhelmed. Even after switching to Titan Form, he was effortlessly struck down by Raven's basic Kuuga Form.
"Why do you have that belt!" Tsukasa was barely able to fight, lasting the longest of the group. "What do you know!" He believed that this person, who also used a Decade Driver, might be the one who knew the secrets of his origins.
However, the only response he received was Raven's cold and merciless attack. In an instant, Tsukasa was sent flying by a sword slash.
The three Riders unconsciously fell down together on the same side, a true picture of comrades in shared misfortune.
"Is he the true Decade?" Wataru asked.
"No, I am Decade," Tsukasa quickly corrected him.
"Perhaps the demon you spoke of is this guy," he said, clearly mistaking Raven for the true mastermind.
"Then let's defeat him and find out what he knows," Yusuke stated. At this moment, the three of them were united on the same battle line.
"Interesting. Then let's use this card." Seeing the three seemingly banding together, Raven pulled out a new card from the belt buckle.
It was the Kuuga Ultimate Form (Black Eyes) Form Ride Card.
"What is that?" Tsukasa noticed the card in Raven's hand, looking slightly surprised. This card wasn't even in his own deck yet.
"FORM RIDE! KUGA!"
"ULTIMATE KUUGA (BLACK EYES)!"
Accompanied by the sound effect, Raven's current Kuuga Form switched to the Ultimate Kuuga (Black Eyes) appearance. His entire body radiated a chilling black aura, looking terrifying and suffocating.
"That form is..." Natsumi's eyes widened. She couldn't help but recall the images from her dreams. Decade's final battle seemed to be against Kuuga in this very Form.
"He has this kind of power?" Yusuke himself didn't know Kuuga possessed this power. He was merely a novice at the moment. Even the later Rising Ultimate Kuuga was a power forcibly granted to him. It could be said that Yusuke Onodera easily received the power that Yusuke Godai acquired through immense hardship and sacrifice, yet he had mishandled it into a state of 'Forgotten Self.' He was truly a disgrace to the Riders.
Raven calmly walked toward the three, who were standing together, looking like the Grim Reaper himself.
"You are too weak." He deliberately lowered his voice to sound intimidating.
"Don't look down on us!" Tsukasa attacked first. Yusuke and Wataru followed right behind.
For a moment, a scene of "Three Heroes Fighting the General" unfolded. To allow the "game" to continue and prevent it from ending too quickly, Raven showed extreme restraint. He stood there without retaliating, enduring the combined attacks of the three Riders. Yet, he remained completely unscathed.
This was the power that Ultimate Kuuga should truly possess.
"How can this be..." Yusuke was utterly baffled. A copy of himself was more proficient with the power of Kuuga than he was...
"My turn now." Raven then unleashed his terrifying power. With a single punch forward, he sent Yusuke flying backward, crashing into a stone wall in the distance and leaving a human-shaped crater. He then deactivated his transformation, completely losing his fighting capability.
His next target was Kiva. Raven walked over, effortlessly subdued Wataru with one hand, and choked his neck, lifting him into the air.
"Le-let go of me..." Wataru struggled desperately.
Raven let out a cold laugh, seemingly intending to choke him to death right there.
Decade saw this and tried to intervene and rescue him. After several attempts, he realized his attacks couldn't even scratch Raven's defense. Instead, he was sent flying by a single slap, his transformation involuntarily breaking.
"Cough, cough..." Kiva had also reached his limit, and the transformation broke. Wataru was covered in sweat, clearly unable to hold on much longer.
Raven was not truly intending to kill him. Instead, he wanted to force someone out: the boss of this world, Wataru's father, the former Fangire King.
Sure enough, seeing Raven seriously trying to kill his son, the Kamen Rider Ixa could no longer tolerate it. He burst out from the shadows and unleashed a thunderous strike toward Raven!
