Manga Hayate No Gotoku!

Ayasaki Hayate is only 16 years old when he was abandoned, leaving him to his fate against the Yakuza, who are hunting for his organs to pay off the huge gambling debt of his parents. In search of a way to somehow get 157 million yen before he is cut by gangsters, he stumbles upon a rich girl who can be kidnapped and redeemed. The only problem: he is a terrible criminal, and in the end saves her life from other potential kidnappers and, apparently, confesses his love for her. To work out her debt, the girl Nagi (who is convinced that Hayate is in love with her) and her maid Maria (who knows otherwise) allow him to work as butlers in their mansion. However, Hayate's stay as a butler is not easy, and he is filled with talking tigers, killer robots, jealous relatives and all-encompassing fun. Serialized in the weekly Shonen Sunday
