Sakura, Nirei, and Suo head to the red-light district Keisei Street to meet Tsubaki. There, they witness the singer Shizuka being chased by thugs. The group intervenes to protect her. During the fight, Nirei uses a defensive technique for the first time, which Suo taught him ("Roly-Poly Tactic"), proving his growth despite initial uncertainty.

The pursuers turn out to be members of Roppo Ichiza, an influential group with historical conflicts against Furin. After clearing up the misunderstanding, it is revealed that Shizuka performs at a bar affiliated with Roppo Ichiza. Their leader, Kanji, apologizes for the unwarranted chase, as Shizuka is actually under their protection.

The episode culminates in an encounter with Tsubaki, who performs on the bar's stage, highlighting Furin's connection to Keisei Street. Humorous scenes, such as Sakura's embarrassment at the romantic undertones between Kanji and Shizuka, lighten the mood. The focus lies on Nirei's development, the importance of trust within the team, and the introduction of Roppo Ichiza as potentially complex allies or rivals.
