Nagi asks Hayate what type of girl he likes, after reading a romance magazine which states that Nagi's zodiac sign, Sagittarius, will face a crisis in terms of romance. Hayate tells her that he likes girls that are normal and makes a passing remark that Nagi "wouldn't understand". Nagi runs off in rage, determined to learn how to be 'normal'. Nagi meets Ayumu Nishizawa and comes to the conclusion that tagging along with her will help her learn how to be 'normal'. After a day of following (and bothering) Ayumu, she invites Nagi to stay at her place. Ayumu gives Hayate a call, at Nagi's request, to inform him that Nagi will be staying over. It turns out that Hayate has been following them. Just as Hayate was about to leave, Isumi calls in distress, trapped at the top of a nearby tower. Wataru rushes to save her before Hayate, but it was ultimately Hayate who did most of the work.
