The Profusion of Blooming Crimson Flowers

Ichigo introduces Rurichiyo to Human-world novelties like vending machines and arcades, nearly letting slip that he is minding her as a favor to Kenryū and Enryū. Dinner at the Kurosaki home turns sour when Rurichiyo refuses to eat carrots and Ichigo insists she honor the farmers' work. Kenryū tells him to back off, which angers Ichigo since the guards asked him to watch her in the first place. Sensing they are keeping something from her, Rurichiyo snaps that she hates them both and storms out, later abandoning her Gigai to wander the riverside as a Soul.

Alone and in tears after a fall, she is found by Orihime, who explains that Kenryū and Enryū only want what is best for her and warns that taking people for granted invites regret once they are gone. The words strike home, and the two set off to return home together, only to be ambushed by a fresh assassin wielding a pole-arm Bakkōtō, Kakuyoku, that raises walls of stone to box them in. Kenryū and Enryū rush to the rescue, followed by Ichigo and Rukia, whose weapons are pinned by the assassin's walls.

Left with no choice, Kenryū unveils his Zanpakutō, Benishidare, which scatters pollen that sprouts flowers wherever it lands to render weapons useless. When the wind from Ichigo and Rukia's techniques blows the pollen clear, the assassin seizes hostages, but Kenryū blinds him with a burst of blossoms and escapes with Rurichiyo, leaving Ichigo and Rukia to finish the fight. The cornered assassin kills himself beneath his own walls. Seeing the wounds her guardians endured, Rurichiyo forgives them, returns to the clinic, and promises to eat her carrots. Elsewhere, Hanza Nukui recovers the dead assassin's weapon, and by morning Rurichiyo has vanished once more.

A quarrel over dinner drives Rurichiyo to flee, exposing her to a second assassination attempt by a Kakuyoku-wielding attacker. Kenryū reveals his Zanpakutō Benishidare, whose pollen sprouts flowers to disable enemy weapons, and helps repel the ambush before the assassin commits suicide. Rurichiyo reconciles with Kenryū and Enryū after witnessing their sacrifices. Hanza Nukui, leader of the assassins, retrieves the fallen weapon, and Rurichiyo goes missing again the next day, pushing the plot forward.

An anime-original episode of the Kasumiōji Conspiracy, on screen as the New Captain Shūsuke Amagai arc, it adapts no manga chapters. It aired in Japan on May 21, 2008, and in English on September 19, 2010, using the opening Chu-Bura and the ending Orange. The Shinigami Illustrated Picture Book segment continues the Men's Association debate over manly cellphone designs, which collapses when Akon reports the Women's Association has slashed their budget.
