History
East Blue Saga
Romance Dawn Arc
When Nami disguised herself as a Marine and entered the 153rd Branch library, Sada confronted her as she did not have clearance to enter. Nami claimed she was looking for a map to the Grand Line on Morgan's orders, and Sada checked with Ukkari to verify this. It turned out Nami had stolen her uniform from Ukkari, and he quickly recognized her, forcing Nami to take down the duo with her staff and escape.[1]
Loguetown Arc
Soon after, Miss All-Sunday, Miss Valentine, and Mr. 5 raided the 153rd Branch, having learned of Mr. 7's death and handover to the Marines. During their assault, Sada and Ukkari were caught in a blast, and tried to run further into the base's courtyard; however, Sada was knocked to the ground by another explosion, and killed by Miss Valentine before she could stand.[2]
