Hayate no Gotoku! Chapter 135:Rozen Maid. A Maid Created by Rozen. I Won't Turn it Into Junk for You. (ローゼンメイド。ローゼンが作ったメイド。ジャンクにしてあげない,Rōzenmeido. Rōzen ga tsukutta meido. Janku ni shite agenai?)
At the end of the chapter, after Maria had asked Nagi if they were being left out, Nagi tells her that they had been left out like a member of a four person group with pink hair, glasses and huge breasts. This is a reference to Miyuki Takara from the series Lucky Star.
