Ep. 31: Sakuya mengunjungi Nagi, yang ingin membuktikan kemampuan adiknya dengan menemukan anak-anak yang hilang di wilayahnya.

Sakuya visits Nagi. Nagi becomes offended when Sakuya tells her she's a brat because she has no siblings and claims she can be a better sister than Sakuya. Nagi orders Hayate to find kids that are lost on her property so she can prove it to Sakuya. Hayate comes back with Itsuki and Shunji, and Nagi plays with them while her SP looks for their parents. Sakuya interfered as she tells Nagi that they should go outside, so the kids liked that idea and hugged Sakuya. Sakuya suspects the kids to be thieves and catches them in the act. As Nagi worries about the children, Sakuya tells Hayate that if Nagi hears the truth about the two thieves, she'll get hurt. Itsuki and Shunji were about to escape with a briefcase until they were caught by the robots. Sakuya ordered her butlers to destroy the robots; Hayate destroys them and saved the two. As they were going to give the briefcase back to Sakuya, she decides they can keep the briefcase as their souvenir. Afterward, Kirika sends the third mysterious butler, Mini Yon, and he challenges Hayate to a Mini 4WD race. (Source: Wikipedia)
