Hayate no Gotoku

Hayate the Combat Butler (ハヤテのごとく, Hayate no Gotoku) is a Japanese manga series by manga author Kenjiro Hata about a boy who starts a new job as a butler and the events he experiences with his employer. The manga is currently on its eleventh volume in Japan. The English edition of the series has been licensed by Viz Media for distribution in North America. The style of the manga has a comedic gag with a slightly harem feel which constantly breaks the fourth wall. The series includes references to other anime, manga, and other things popular culture. An anime adaptation of the manga started airing on April 1, 2007 on TV Tokyo.

wiki-chan of course

One of the best April series (aside from Lucky Star, Tengen Toppa Gurren Lagann and Seto no Hayanome), it's amazingly hilarious, full of parodies. Currently the anime has reach episode 13, where it's scheduled to have 50+ episodes (omg, that much...?). As for the manga, it's still ongoing, currently at vol 11, while I've just finished reading until vol 2.

Basically the story can be summarize as this: An unfortunate high school student, Ayasaka Hayate spends his days working at part-time jobs to support his extravagant parents. After incurring a debt of 150 million yen, they disappear, and Hayate was left holding the bag. Whilst running away from the debt collectors, he tries to kidnap a girl for ransom. However, the girl misunderstands his intentions and thinks he is confessing his love to her. Almost immediately, he botches the kidnap attempt but then manages to save her from other kidnappers, causing her to fall in love with him. The girl, Sanzenin Nagi, is actually the daughter of a millionaire family. In recognition of his services, she hires Hayate as a resident butler and even pays off the debt collectors. This is how Hayate becomes a combat butler. In order to serve and protect his mistress, Hayate’s life-or-death butler life begins.

Put the story aside, this series is freakin hilarious, worth to enjoy for comedy/parody theme enthusiast. Among them parodies includes Haruhi, Dragon Ball, Inuyasha, Fist of North Star, Tengen Toppa Gurren Lagann, Hetsumen to Heiki Mina, Gundam, Sadako, Kayako, Jason&Freddy and so much more. Not to mention, lolis and maids :33
Right now I'm enjoying the manga, while waiting for episode 14 to be released. The content of the anime is very similar to that on manga, except with some irregular arrangement of events. But basically there's no significant change in term of story. And, Hinagiku appear pretty late in the manga (even after vol 2, she still hasn't make her appearance)
