This is a 30 pages long doujin from the first Mekimeki Oukoku Omnibus, originally published in 2008, and is an assortment of small stories and a couple of 4-komas released that year. You can find the first part of this book Here.
The "rabu rabu" is strong in these stories, and Hayate loves to play dangerously with her life (maybe she's a closet M).
I really enjoyed the stories. They were great for my recovery.
the both of them are so cute. this stories really make me happy after reading all some sad nanofate fic.
I love how sweet NanoFate is. I can kind of understand why Yagami might be a little grossed out. Even so Nanoha and Fate are just so gosh-darned cute!
