“Also known as... Kamen Rider Blade.”

Without another word, Kazuma reveals both the Change Beetle (♠A) Rouse Card and the Blay Buckle to Tsukasa, inserting the former into the Card Slot of the latter. A red belt, the Shuffle Wrap, shaped like a red card itself, extends and tightens securely around Kazuma's waist automatically.

“Henshin.” Kazuma declares coldly. He then pulls the Turn-Up Handle on his right side of the Rouse Craddle with his right hand, activating the Orichalcum Element.

(Turn Up!) The Orichalcum Element is then released from the Element Radiation Muzzle on the Blay Buckle, but unlike the usual blue-colored transformation screen that features the image of the Change Beetle (♠A) Rouse Card, this one is golden-colored, displaying the image of the Evolution Caucasus (♠K) Rouse Card instead.

At this, the golden transformation screen is then projected through the Blay Buckle on Kazuma's waist, only to then move forward Tsukasa, pushing him away with a cruel, electric golden-colored thrust as the latter stands in its way. The Orichalcum Element only permits a compatible individual to pass. Anyone else is repelled mercilessly, like in this case.

Right after that, the golden transformation screen featuring the Evolution Caucasus (♠K) Rouse Card then advances backward over Kazuma after he pulls the Turn-Up Handle, instantly transforming him into Kamen Rider Blade – King Form. Unlike his original counterpart, this version of Kazuma only requires the Blay Buckle and the Change Beetle (♠A) Rouse Card to transform into his King Form directly. This version of Kazuma can directly transform into his King Form without the need for the Rouse Absorber at all. He can bypass his default Rider form, requiring neither the Rouse Absorber, the Absorb Capricorn (♠Q) nor the Evolution Caucasus (♠K) cards respectively.

At his golden transformation sequence getting fully complete now, both of his visor eyes now glow into a menacingly red color as the green gem between them flares briefly at the same time as well, signaling the absolute completion of his golden transformation sequence.

Now fully clad in his fully imposing golden Rider armor, Kazuma starts walking forward Tsukasa menacingly and hostilely. The strong King Rouzer instantly materializes in a gold-colored light into the right hand of the former as part of his sequence transformation while walking menacingly and hostilely forward the latter.

“So?”

Kazuma raises the tip of the King Rouzer at Tsukasa’s chest while walking forward him menacingly and hostilely. The stance of the former offers no room for negotiation in the slightest for the latter.

“What's it going to be, then?”

Kazuma grips the King Rouzer tightly, his completely cold voice cutting through the silence as he walks forward Tsukasa menacingly and hostilely without feeling remorse or mercy in the slightest for him.

“Will you leave this World for good?”

At this, Tsukasa answers nothing in return. Kazuma’s tone grows even more remorseless, merciless, ruthless, cold and serious on him now.

“Will you leave this World right away?”

Kazuma continues walking forward Tsukasa more menacingly and hostilely at his silence as the former aims the tip of the King Rouzer at the chest of the latter with a clearly anti-heroic intention.

“Or will you continue allowing the fusion of all the Worlds at the hands of Dai-Shocker because of your annoying stubbornness to leave this World at once? The World of the Great Rider War.”

Kazuma’s patience is starting to run out very quickly on Tsukasa now. The steps of the former start growing heavier, more aggressive, as he approaches the latter menacingly and hostilely, the former completely ready to kill the latter with the King Rouzer without remorse and mercy in the slightest despite the latter haven't even transformed into Kamen Rider Decade yet at all.

“What's it going to be, Decade?”
