Friends of the Well-Behaved, Praise the Debt-Ridden Butler!.Nagi feels that it is all because of her that Hayate quit his job, while Maria tries to comfort her and wonders where did Hayate go. Meanwhile in Hakuou's dome, Kirika asks Hayate to wear the ancient butler robe which has been rejecting countless butlers. In exchange, she promises to leave Nagi and her fortune alone. Hinagiku found out about Hayate, she calls Nagi that Hayate was getting blackmailed over the Sanzenin estate. Nagi, Hinagiku, Himegami and the SPs come to Hayate's rescue, but they arrive too late, as Hayate has turned into a nekomimi maid. They battle Kirika and Shion who're under the curse of the white snake and during the battle, Nagi's pleas reach Hayate. The nekomimi maid uniform transforms into the legendary butler uniform. With his newfound power (Ultimate Move), Hayate defeats Kirika's white snake, Jörmungandr. When the dome starts to collapse, Hayate, Nagi, Hinagiku, and Himegami managed to get out of there, to their safety. Himegami gets a hold of the legendary butler uniform, and then disappeared. Kirika and Shion somehow survived and still flirt each other. Realizing that it's still Christmas, Nagi made a stop at Loser Park, Hayate and Nagi wished themselves a Merry Christmas the place where they first met each other.
