Hayate Ayasaki's tragedy continues to come back to bite him. The butler, now settled into his routine at the Sanzenins' mansion and Hakuou Academy, continues to work as hard as ever in caring for his young mistress Nagi while studying the school's arduous curriculum—all while trying his best to survive the multitude of problems that life relentlessly throws at him. The unintentional chick magnet's life is anything but quiet, as he must deal not only with Nagi's yet unnoticed infatuation with him, but also with an ever-growing string of accidentally seduced girls, most notably the exceptionally plain Ayumu Nishizawa, a friend of his before he became a butler, and the diligent Hinagiku Katsura, Hakuou's student council president. While one is attempting to achieve his affection and the other desperately tries to deny her own, both the girls are going to make the boy's life a little more complicated than it already is.
