Ep. 4: Shiroe and allies face Brigandia ambush in Susukino before returning to Akiba.

Shiroe, Naotsugu, Nyanta, and Serara arrive in Susukino, wary of a Brigandia ambush. Shiroe reunites with Nyanta and Serara, learning Nyanta protected her. They execute a plan to leave, but are surrounded by the Brigandia guild. Shiroe provokes Demiqas into a duel with Nyanta, whose swashbuckler sub-class inflicts severe status ailments. Demiqas calls for aid, but Naotsugu intercepts the reinforcements. Both Naotsugu and Nyanta suffer critical health drops, requiring Serara to heal them. Despite limited healing effects, Naotsugu draws enemy fire, buying time for Shiroe to ensnare Demiqas. Nyanta defeats Demiqas while Akatsuki observes their teamwork. Serara delivers the final blow to protect Shiroe. With the mission complete, the group summons three griffons and travels back to Akiba.
