What is the plot?

The episode begins with the tournament to determine the strongest Kamen Rider officially commencing. The first match pits Tojima against Yukarisu. Tojima approaches the fight with an unusual demand--he kneels before Yukarisu and begs her to transform into a Shocker Combatant. His reasoning is clear: he has no interest in fighting a normal girl. He wants to face an actual Shocker combatant in combat. When Yukarisu initially refuses, Tojima goads her further, pushing her toward transformation. Eventually Yukarisu relents and transforms, her transformation sequence notable for the way her "eeeeeee" sound emerges as part of a sentence mid-speech. Once transformed, Tojima finally has the opponent he desires and the fight between them proceeds.

The episode then transitions to the second match of the tournament: the sibling showdown between Ichiyo and Mitsuba Shimamura. This fight serves as the emotional and narrative payoff to all the backstory about the Shimamura brothers that has accumulated throughout the series. The core conflict driving this match stems from over a decade of resentment. Mitsuba has lived in Ichiyo's shadow for all that time, forced into the role of sidekick while his older brother claimed the position of hero. The unfairness of this arrangement is underscored by a simple fact: if not for the age and physical development difference between them, Mitsuba would never have been relegated to a secondary role in the first place.

During the fight itself, Mitsuba demonstrates that he has trained extensively to defeat his brother. He employs Aikido techniques with precision, countering every move Ichiyo throws at him. Each of Ichiyo's punches and strikes is met with a counter, with Mitsuba redirecting his brother's own energy and momentum to throw him repeatedly to the ground. The fight reaches a critical moment when Mitsuba moves to break Ichiyo's arm, mirroring the injury Ichiyo inflicted on him years earlier when they were fighting to determine who would become V3. However, Mitsuba stops himself at this point--the fight is over for him the moment he breaks his brother's arm.

Ichiyo, by contrast, refuses to yield. He continues fighting even as he is being beaten, even as his arm is about to be broken. This reveals a fundamental difference in character between the brothers. Mitsuba possesses empathy; he recognizes when he has won and when continuing would be cruel. Ichiyo has only trace amounts of empathy. If Mitsuba were willing to break his brother's arm on a whim the way Ichiyo once did to him, the fight would be half as long. But to Ichiyo, the fight is only truly over when his opponent is unconscious. He is not there to be beaten by Mitsuba--he is there to train him, to make him understand what it truly means to be a Kamen Rider, to awaken him to the reality that he is not just any rider, not even V3, but Riderman.

The brothers continue their exchange, trading their strongest rider punches against each other. Through this final clash, Mitsuba reaffirms to himself that he is glad to be Riderman--not a sidekick, but the true fourth Kamen Rider. With this victory, Mitsuba has finally managed to surpass his brother. The fight concludes with both brothers arriving at a newfound respect for each other, their long-standing conflict resolved through combat and mutual recognition of each other's strength.

What is the ending?

In a short, simple narrative fashion, the episode ends with Mitsuba and his brother Ichiyo trading their strongest Rider punches in an intense sibling showdown, culminating in Mitsuba breaking free from his sidekick shadow by affirming to himself that he is proudly Riderman, the true fourth Kamen Rider, having finally surpassed Ichiyo.

Now, let me orate the ending to you in full chronological narrative detail, scene by scene, as the chaos of the ultimate tournament fades into this raw brother-against-brother climax, painting every punch, every grimace, every bead of sweat under the harsh arena lights.

The scene opens in the dimly lit tournament arena, surrounded by cheering Shocker combatants and confused onlookers, where the earlier footnote fight between Tojima and Yukarisu has wrapped up in comedic frustration--Tojima, refusing to strike an untransformed girl, begs and goads her with taunts until she lets out her drawn-out "eeeeeee" transformation scream mid-sentence, her body twisting into her Shocker fighter form with crackling energy and glowing eyes, but the match fizzles quickly as Tojima holds back, disappointed it's not a proper Rider clash, leaving Yukarisu sprawled unconscious on the ground afterward, her chest heaving as Tojima hovers worriedly, muttering regrets while onlookers stare.

Cut to the heart of the episode's payoff: the Shimamura brothers' grudge match ignites under the spotlights, a decade of resentment boiling over since Mitsuba, as a middle schooler, scrapped against his college-sophomore brother Ichiyo back in eighth grade. Mitsuba, transformed as Riderman with his sleek green armor scarred from prior battles, faces Ichiyo, the towering original hero in his classic black-and-green Kamen Rider suit, veins bulging on his neck as he smirks with cold confidence. The brothers circle each other slowly, boots scraping the concrete floor, Mitsuba's fists clenched tight from years of living in Ichiyo's shadow--forced into the sidekick role not by choice but by age and physical gap, his heart pounding with the unfairness of it all.

Ichiyo lunges first, empathy a trace flicker in his eyes, grabbing Mitsuba's arm and snapping it with a sickening crack on a whim, the bone audibly fracturing as Mitsuba cries out, dropping to one knee in agony, sweat pouring down his face inside the helmet, his empathy halting him from retaliating with equal brutality--he could end it there, but his compassion for his brother holds him back, turning the fight into a grueling marathon.

Mitsuba rises shakily, arm dangling limp, pain shooting through his body with every breath, but he presses on, dodging Ichiyo's relentless haymakers that crater the arena floor, each miss sending dust clouds billowing. Ichiyo, unyielding, declares the fight far from over even as Mitsuba weakens, pounding him with hooks and uppercuts that dent Riderman's chest plate, blood trickling from Mitsuba's split lip beneath the visor, his breaths ragged, muscles screaming from the imbalance--he's the empathetic one, unwilling to cripple his own blood like Ichiyo did without hesitation.

The brawl drags on, minutes feeling like hours, brothers trading bone-jarring blows amid the roaring crowd, Mitsuba's broken arm flopping uselessly as he counters with his good fist, finally landing a solid hit that staggers Ichiyo back, the hero's helmet cracking slightly at the jawline. Empathy defines Mitsuba here, shortening what could have been endless savagery, while Ichiyo's ruthlessness demands total submission--unconsciousness or nothing.

In the final exchange, they rear back simultaneously, channeling every ounce of Rider power: Ichiyo winds up his strongest punch, fist glowing with green energy, knuckles white; Mitsuba mirrors him, good arm cocking back despite the pain, Riderman's systems whining in overdrive. They collide in a thunderous Rider Rider Punch clash--fists smashing together with explosive force, shockwaves rippling outward, cracking the arena barriers, sparks flying as armor grinds metal on metal, both brothers staggering from the impact, helmets smoking, bodies trembling on the brink.

Ichiyo crumples first, eyes rolling back inside his helmet as he hits the ground unconscious, defeated at last. Mitsuba stands victorious, chest heaving, broken arm throbbing, but a quiet affirmation swells in his mind amid the adrenaline crash: he's glad he is Riderman--not a sidekick, but the true fourth Kamen Rider, finally surpassing his brother, shadow lifted, a surge of pride washing over the pain as the crowd falls silent.

Fates of the main participants in this ending: Mitsuba Shimamura (Riderman) emerges triumphant, arm broken but spirit unbroken, poised for uncertain future fights against Tojima or Yuriko, his arc complete in stepping out of Ichiyo's shadow. Ichiyo Shimamura (Kamen Rider) lies unconscious on the arena floor, physically bested and emotionally overshadowed for the first time, his ruthless dominance challenged. Tojima Tanzaburo watches from the sidelines, locked in mentally but physically unscathed from his earlier bout, still chasing his dream without resolution here, screaming internally during transformations but holding back against Yukarisu. Yukarisu slumps passed out nearby from her quick knockout, body limp and vulnerable post-transformation, drawing Tojima's worried concern as she stirs faintly.
