After spending almost an hour contemplating to whether post this or not, my VK anniversary spirit took over and
commanded me to put this up. I am extremely sorry for the horrible quality of the pic as I have taken it with my camera phone with bad lighting. I will definitely upload the good quality version once I got my hands on a scanner.
The whole omake drawn into 4 panels. It was a wacky idea that I gotten a week ago. I was thinking of producing it in fanfiction format but I figured I have no time to do so. So, I doodled it instead. It started with a very rough sketch only 2B pencils and I thought it was too dull to be captured by the camera... So, I did some experiment with the ballpen and highlighters instead... Din know it turn out quite nice!
Anyways, for reading purposes I have labeled numbers on each panel. However due to the horrendous pic quality, I would bring you through the panels in order together with the dialog so you would understand better. (I promised I would upload the gd quality ones once I got my scanner, which is current out of order and seeking aid at the IT center. )
Overall, this is how the whole omake looks like:
Panel 1: 
Hino Matsuri, the mangaka for Vampire Knight was searching for something in the heap of rubbish laying on the side of her work desk. Actually, she was finding for Aidou Hanabusa's request letter that was supposed to be at her desk last week. (
That is after he had called her through his cell, asking Hino-sensei whether she did received it.)
So in the panel, you see things flying evrywhere. Amongst them are an empty box of blood tablets, a Bloody Rose water gun, Kaname's bat soft toy and
someone's bikini... [ dun ask.. I have no idea... its random AU stuff...]
Hino sensei: Where is it? I'm sure I kept it here somewhere.... Panel 2: 
After searching for almost two hours, she found a piece of paper, half-crumpled together with the rest of her doodling paper. She read it.
Hino-sensei: Found it! It's from Aidou!
[reads letter]
Letter:
Dear Hino-sensei, I would like to request for a portrait of Kaname-sama for VK anniversary tomorrow.
Really appreciate it! :)
P/s: Please let it be a surprise! Dun tell Kaname-sama, okay?
Yours Truly,
Aidou HanabusaPanel 3

Hino sensei finished drawing and had delivered the wanted portrait for framing under LaLa magazine's special fund. She got approval from her supervisor as she managed to convince her boss that it would boost sales for the magazine for tomorrow is VK's 5th anniversary... Besides, who can resist the super hot Kaname portrait drawn by Hino-sensei? *note: LaLa's boss is hardcore fan for Vampire Knight bishies and is secretly feeding her mind with possible yaoi situations (ignore me cause I'm rambling here)*

Hino-sensei: Right on time! Hopefully they would like it! ;) (yawns) Need to get some sleep now....
Panel 4

12 hours later, during the interchange of class student, Yuuki spotted the Night Class girls including Kaname-senpai's inner circles were crowding in front of a new portrait in the hallway. Her mouth gapped open when she saw the portrait was not other than her senpai posing semi naked with only white satin to cover his lower body. Yuuki felt her temperature rising as a result, face flushed from the "interesting" images that she could conjured. She noted them mentally so that she could have more ideas when she blogs about VK yaoi on her LJ account. *note: Ever since she had access to the Internet in Cross Academy, she had discovered a myriad of yaoi possiblities with her VK peers especially Kaname & Zero [Yuuki's inner mind
drools at SGK' sand BlackenedWing's fan materials]*
Yuuki: *sweatdrops*
Ruka: Is that who I think it is? *~shivers at though and flushed at the S&M thoughts that arose in her naughty mind ~* [Note: Kaname is supposed to be uke material in yaoi fandom.]
Rima: Who could have done such a cruel thing? {(inner swearing) Damn those yaoi fangirls.... Why can't Hino-sensei put my beloved Shiki on it? I bet Takuma-senpai won't mind it.... }
Panel 5

Aidou was totally shocked when he saw the painting on the wall. He was very thankful that Hino-sensei, the Almighty mangaka had granted his wish after being rejected for almost 4 years now. (
Hino-sensei apparently was higher preference for her angsty Zero and his cousin for reasons that Aidou could not comprehend...)
A furious, evil emitting aura Kaname stepped into the hall shouting at the blonde vampire after Takuma had teased him mercilessly about his appearance after Calculus Class. In addition to that, he saw his Facebook account was flooded with yaoi fangirls' messages on his wall post, almost to the point where he actually tagged them all as spams. He is so
NOT going to let Aidou get away with this...
So, what awaits our poor blonde vampy? Well, its up to you to decide the ending....
Last but not the least,
Happy 5th Vampire Knight anniversary!
