What is the plot?

The private room at Futaba's pub lies in complete disarray following the fight with Nakao from the previous events.

Futaba, filled with rage, suddenly appears before the stunned Tojima and the others in the room.

Ichiyo, caught off guard, flees the scene without thinking.

Futaba chases after Ichiyo relentlessly, determined not to let him escape.

The pursuit ends as Ichiyo and Futaba finally clash directly.

Futaba unleashes her deep-seated resentment and hatred toward her brother Ichiyo, exploding with emotion at this breaking point.

Flashback reveals Ichiyo's childhood trauma: he witnesses a Shocker deserter and his girlfriend violently attempting to murder their neighbors, followed by the actual murder of his grandparents.

No one believes young Ichiyo's account of the events except Mitsuba, who also witnessed the incident; neither the police nor his sister Futaba accept his story.

Ichiyo's child mind interprets the trauma by concluding that Shocker is real, and since only he and Mitsuba know, it is their duty to defeat it.

Ichiyo decides he must become a Kamen Rider--specifically V3, his and his grandparents' favorite--to fight Shocker.

From that point, Ichiyo lives in a delusion where he is a Kamen Rider, viewing everyone around him as side characters in his personal story.

He forces others into these roles, culminating in his past decision to break his own brother Tanzaburo's arm as the most extreme example.

In the present clash, Ichiyo comes to understand that while Shocker is the villain in his life, he himself is the villain in Futaba's life.

Ichiyo feels deeply hurt by his sister's hatred and expresses sorrow for his actions, though still framed within his deluded worldview.

Despite this realization, Ichiyo refuses to abandon his fight against Shocker.

Tiger Master is introduced as the person who taught Futaba to fight, wearing a distinctive pink tiger mask.

Tiger Master is revealed to be an imposing police woman with short hair, formerly a cop who busted some Yakuza, which is why she wears the mask for protection.

Tiger Master beats kids during training, including making them bleed, but it is all part of the rigorous process.

Ichiyo, pretending to be V3, fights Futaba in a training scenario.

Ichiyo gains the upper hand by closing in on Futaba, slamming her to the ground, and knocking her out face-first into the dirt.

Ichiyo feels upset about this victory because he does not view it as a proper win in his Kamen Rider delusion.

Everyone leaves the pub after these events.

Spider-Man, acting as an assassin for the Yakuza, speaks with one of the Yakuza members.

Spider-Man receives the job to assassinate Tiger Master.

Futaba learns about the assassination plot against Tiger Master.

Futaba arrives at a scene, followed immediately by Ichiyo, who shouts "retreat" and jumps through a window to escape.

Tojima mentions that in this episode, Kamen Rider threw a trillion yen into the ocean, prompting the group's reaction.

Futaba delivers a line to someone presumed dead: "You've been dead 30 seconds and you're already haunting me," after thinking she beat them, but they start talking from the ground.

Tiger Master, facing a threat possibly from Shocker bosses, agrees to train the rest of the riders.
