Kamen Rider 555: Paradise Lost

Takumi Inui hides in a beleaguered human refuge called Paradise, living under the alias Takeshi and making a living as a cobbler. He shares a cramped home with a girl named Mina, trying to stay out of the mounting war between humans and Orphnochs. The memory of his Faiz-bearing past haunts him, even as he avoids stepping back into the hero role.

Riotroopers crash a masquerade in Paradise, shattering Takumi's fragile quiet. Kusaka Kaixa attempts to confront Psyga but is swiftly defeated, revealing the Emperor Belts are at stake. The invasion exposes Smart Brain's reach and the peril that awaits both humans and Orphnochs.

During the chaos, Takumi's memories of his Faiz days return, reigniting his resolve. He reclaims the Faiz identity and rejoins Auto Vajin to repel the attackers. Mari and the resistance realize the danger of his hidden past but also the hope he represents.

Mina reveals that her father saved Takumi years ago and implanted false memories to protect him. The truth fuels suspicion that Takumi may be an Orphnoch, despite his Faiz powers. Mari's rumors about his savior past drive a growing rift within the resistance.

Mina is fatally shot by Mizuhara, a resistance member, as the group scrambles to secure the Emperor Belts. Mizuhara steals the Faiz Belt amid the chaos, triggering a furious chain of events. Yuji kills Mizuhara and retrieves the belt, but the resistance exile Yuji, Naoya, and Yuka until they prove themselves worthy of joining the Emperor Belt mission.

On the heels of that fracture, the Orphnochs pressure Smart Brain HQ, unleashing the colossal Elasmotherium Orphnoch. Yuka dies in the assault, and Naoya is devoured by the behemoth in a brutal display. Smart Lady manipulates Yuji into believing Mari betrayed them, deepening the division within their ranks.

A serum devised by Professor Nomura enables Keitaro Kikuchi to transform into Kaixa and briefly rescue Mari. The Kaixa Belt dissolves into dust soon after, underscoring the fragile nature of the Emperor Belts. The moment highlights how quickly fortunes can turn in the war.

Psyga abducts Mari, spreading discord within the resistance and further fracturing their unity. Takumi's resolve hardens as he realizes the threat is bigger than personal history. The disappearance of Mari compels him toward a desperate rescue mission.

Takumi leaves Paradise and races to Tokyo to rescue Mari, determined to avert Psyga's power from tilting the balance of control. The journey piles pressure on his relationships with those who doubted his loyalties. The mission sets the stage for a high-stakes confrontation with the Emperor Belts' wielder.

In the Smart Brain Super Arena, Mari is slated to be fed to the Elasmotherium Orphnoch before a global audience. Takumi interrupts the event and, as Faiz, charges the behemoth head-on. Auto Vajin is destroyed, Psyga’s interference escalates chaos, and the Elasmotherium is restrained to prevent stadium-wide catastrophe.

Yuji Kiba arrives wearing a second Emperor Belt and becomes Orga, tilting the balance of power against Takumi. Orga and Takumi clash, forcing Takumi out of Faiz and into a raw Rider duel that leaves both fighters exposed. Mari is captured once more to be fed to the monster.

Faiz, in Blaster Form, defeats Orga, ending the direct threat but at a steep cost. A dying Yuji urges Takumi to pursue a lasting peace between humans and Orphnochs. Murakami's severed head is crushed, symbolizing the collapse of the old regime.

Under a somber sky, Takumi and Mari walk away together, vowing to seek a place where humans and Orphnochs can coexist. They understand the road to peace will be fraught, but their bond offers a glimmer of hope for the future. The world remains fragile, yet their commitment hints at a possible new dawn.
