Though things got off to a rocky start, Kiddy's relationship with Sergeant Ralph Bombers seems to be working out, or at least that's what the grin on her face at work would lead her AMP teammates to believe. Emerging from yet another daydream, Kiddy finds the rest of the group laughing at her giddiness, and she's none too happy about it. She needn't be embarrassed for very long, however, as attention shifts toward Nami Yamigumo's shocking revelation that she never even thinks about having a boyfriend. Nami usually keeps her feelings bottled up, but this statement is far too interesting not to investigate further. Unfortunately, any probe into her personal life will have to wait, as Nami's sister unexpectedly arrives at AMP headquarters with the intention of brining her home. At her grandfather's request, Nami is to take a leave of absence from her police duties so that he may pass on to her a sacred sword in a ceremony naming her as heir to the powerful and revered Yamigumo clan.
