Aim for the King! - S2.E19

Nagi, having woken up after noon for all of spring break, resolves to rid herself of her hikikomori lifestyle. After Hayate accidentally breaks his cell phone, Hayate and Nagi go shopping in Shinjuku to replace it. Nagi gets lost, although she vehemently denies it, and is directed to the lost child section of the electronics store. Nagi challenges the boys there to a duel with the Hayate the Combat Butler Trading Card Game; she wins and tells the boys to call her "boss", after which Hayate arrives to pick her up. On March 29, Sakuya reminds Hayate that her birthday is on April 3. Knowing that Hayate cannot afford to buy her a present, she asks for a good laugh. In an attempt to learn how to be funny, Hayate forces himself to try and jab at Maria but instead trips and face-plants her chest. Nagi beats up Hayate as a result, and Sakuya gets the laugh that she asked for, although she tells Hayate that she still expects something on her actual birthday.
