Hayate no Gotoku!!

Synopsis

Hayate asks Maria what she would like to get an idea of what girls his age want so that he can figure out what to buy Hinagiku for her birthday. Hayate goes into town and chances upon Ayumu, though they are initially awkward toward each other after remembering the events of Valentine's Day. Izumi, Miki, and Risa show up as well, and they help Hayate look for a present. Hinagiku finds them and finds out about Hayate looking for a present for her. Hayate says he does not have the financial means to support a girlfriend at this time, so while he does not dislike Ayumu, he cannot bring himself to get involved in a relationship after explaining the ex-girlfriend he had back in kindergarten 10 years ago. Back at the mansion, Hayate asks Maria when her birthday is, but Maria evades the question, causing Hayate to think he said something tactless. He apologizes to her and finds out Maria was abandoned by her parents, never knowing her birthday or her real name, though her birthday is set on December 24, the day she was found. Athena Tennousu makes a cameo appearance.
