Hayate no Gotoku!

Synopsis

Nagi, still in her hypnotic state, helps organize the second day of the school festival with the help of Superintendent Kirika. They organize their own Comiket where Nagi sells her own dōjinshi. Then Shion couldn't take it anymore and wants Hayate to take Nagi back. Kirika challenges Hinagiku to see if Nagi's dōjinshi or Hayate's butler cafe can make the most money. If Hayate wins, Kirika must return Nagi back to him. Kirika then gives them her only warning, because if Hayate loses to Nagi, the student council members must run a maid cafe in their embarrassing outfits, so Hinagiku accepts her terms. During the Hakuou culture festival report, the reporter interviewed Hayate as he answered her questions about how did he make a cake that's so delicious. Hinagiku started working part-time, Koutarou and Kaede volunteer too. Kirika just made her backup plan by giving out prizes with the manga. Hinagiku noticed Nagi and opened the door. When Nagi comes and tastes the Christmas cake that Hayate made for the competition, her hypnotic state goes away and he hugs her. They win the competition against Kirika at the last minute, thanks to Nagi's big payment to the butler's cafe for 2000 members of the SPs. Later that night, Nagi makes Hayate cosplay as punishment for making her worried.
