Later, Nagi gives Hinagiku the watch she prepared for her birthday, and then becomes kidnapped by Kotetsu, who says to have Hayate rescue her. Meanwhile, everyone surprises Hinagiku with a surprise birthday party, and after being asked where Hayate's present is, Hinagiku misunderstands the letter of challenge as a way for them to be alone. After hearing that Nagi has been kidnapped, Hayate runs through the festival even though he is wearing embarrassing clothes. Nagi talks with Kotetsu about how shallow his love is, and how he only looks at the appearance of others. This opens Kotetsu's eyes and he confesses his love again to Hayate, but is beaten away by Nagi. Nagi also scares away the curse of the Hina Doll and Hayate returns back to normal. Finally, Nagi and Hayate head home, but Hayate remembers that he forgot to meet up with Hinagiku, and heads to the clock tower where Hinagiku is sleeping.
