As Ringo gets help from Himari preparing lunch for a 'date' with Tabuki at the park, Kamba tasks Shōma to go with her and look through her bag for her diary, believing it may be related to the Penguindrum. When they reach the park, they encounter a runaway skunk who runs off after squirting Ringo in stink. After changing clothes, Ringo and Shōma meet up with Tabuki, who brings along the woman Ringo saw him with, an actress named Yuri Tokikago. Come lunchtime, Ringo's prepared lunch gets eaten by crows, leaving her in the shadow of Yuri's picnic. In order to fulfil a 'first kiss' note in her diary, Ringo plans to jump into the pond and have Tabuki save her. However, the skunk appears again and knocks her in, forcing Shōma to save her instead and use CPR on her, though Ringo believes Tabuki to be the one who did it. Later that evening, a girl that Kamba met up with earlier is pushed down the escalator of a train station, completing the description in Ringo's diary.

After realizing that she was tricked by Yuri, Masako reminisces about her grandfather, a powerful business tycoon who expelled her father claiming that he was not strong enough to be allowed a place in the Natsume family. After dreaming countless times about having him killed, Masako rejoiced when her grandfather inadvertedly poisoned himself to death by eating ill prepared Fugu. Masako since then assumed control of her family's corporation but was sad that her father had never returned home, until somehow her grandfather's spirit posessed Mario's body and forced her to eat the same poison that killed him to protect her brother, but Sanetoshi appears to save her life. Later, Masako sees Kanba hanging out with the same elusive men who took her father away and Sanetoshi asks Masako to join them in his plan to "put the world back on track" but she promptly refuses.

On the day of the terrorist attack, 16 years before, Sanetoshi is contronted by Momoka who was determined to stop him and while her spirit ends up split in two with each half becoming the penguin hats used by Himari and Mario, his is divided into the two black rabbits that always accompany him. Back to the present, Shouma is informed that Himari's life is at its end and Ringo conforts him while Kanba is taken by Sanetoshi to a gravely injured Masako and brings her from the dead before his eyes. Despite Masako's pleas, Kanba leaves with Sanetoshi to continue his plan, carrying her half of the diary with himself. Shouma sees a vision of Himari asking him to stop Kanba, and when his brother comes to fetch her, he is shot unconsious by him with a penguin bullet. Ringo is called by Kanba to the aquarium and a bomb explodes knocking her out. Sanetoshi watches her struggling to stop her half of the diary from being burned out and after she fails, he has Kanba burn the other half. Shouma wakes up and manages to reach Kanba determined to stop his plans.
