Ep. 15: Hayate and Nagi encounter Saeki and Taiga before Hayate challenges a Kendo club member.

Hayate and Nagi travel to school together, where they meet butler Himuro Saeki and student Taiga Ookouchi. After Saeki steals Hayate's necktie, the pair retrieve a replacement. Hayate learns Nagi skipped grades to become a high schooler despite her young age. He reflects on his gratitude toward Maria and Nagi, though Hinagiku interrupts Nagi's blush to announce her departure to the clubroom. Hayate recalls Nagi previously quit Kendo with Hinagiku and resolves to reintegrate her into the club to end her isolation. At the Kendo club, members view Hayate's interaction with Hinagiku with suspicion during training. Hayate accepts a challenge from a club member for Nagi's benefit, just as Himuro and Taiga arrive on the scene.
