Hayate the Combat Butler: It's summer vacation, and Hayate decides to spend this free time trying to come up with an ultimate attack. He, Nagi, and Maria conveniently find a book that teaches ultimate attacks in the mansion's book vault. During training, Hayate explains how he promised to show off his ultimate attack to Hinagiku.
