Chapter 3 has Arf break into Negi's apartment. She ends up finding everyone's favorite chain-smoking ermine and, more importantly, a fresh new batch of his mystical chocolates. Later it's discovered that said chocolates are essentially magic Red Bull, but for Arf, they act like the best aphrodisiac ever. What follows is one long sequence of Arf dry-humping a hapless Zafira. Signum's response?
Signum: "Zafira, I think you're doing it wrong."
Signum also drops another punchline after Vita wakes up on the kitchen table after Hayate got some very interesting noises out of her.
Signum: "You know there is a reason why Shamal and I sleep in another room. I would have hoped you could contain your antics to one room of the house."
Chapter 4: Negi walks in on Fate changing, and Arf lampshades her ironing-board status. Fate is not amused.
There's another one in the Chapter 10 omake where, after reading a hacked chatroom log, Chachamaru delivers this gem:
Chachamaru: "Perhaps the meme is insinuating that Chisame-san is using some form of device in order to properly penetrate the miniature horse."
Albireo Imma gives Negi the Stealth Hi/Bye treatment when he decides to call KFC "Albireo Chicken."
Nanoha finally gets to test her skill against Negi. Too bad Puberty has decided to kick in, and with Negi constantly in her face, she has to revise her Badass Boast:
"I have fought demons, monsters, robots, and summons, I have faced down the darkest depths and rescued my precious ones from its grasp. There is no obstacle I cannot surpass, no foe I that can outrun my shot. I am Takamachi Nanoha, ANDI AM NOT A PERVERT!"
The beginning and ending notes of Chapter 21.
Just remember: Everything is happening for a reason.
So, as a final departing gift, I need to fulfil a dare someone on the forum passed to me
ZOMG U GUYZ, PLZ REVIEW OR I NO UPDATE. ALSO, ME WANT FANARTZ, BUT ME NO PAY
Arika, Negi's mother, doesn't let Kurt Godel off easy: She specifically built his cell with incredibly thin walls and right next to her and Nagi's room. This way, when the two have sex, Godel will hear EVERY DETAIL. Not only that, he's cursed so that he can only see his papers at night (which is when the sex happens), and should he ever think about Arika...
