Hachikai (Circle)

A short comedy doujin in 4-koma format, with strips about Nanoha and Fate during Valentine's day, and the very inappropriate gift of the later one.

A short doujinshi about Fate having a nightmare about her infancy, and Nanoha comforting her. There is also a small extra story at the end.

Nanoha has agreed to go out with Yuuno-kun, a decision that destroys Fate. Years later that memory is still pestering in the mind of the young blonde, who has chosen to remain close to Nanoha no matter that her feelings are not the same as hers.

A comedy about Fate getting very obsessed over Nanoha, to the point that she even gets jealous of their own daughter, Vivio, and gets involved in other bizarre acts. Guaranteed hilarity.
