DISCAIMER: I DO NOT OWN DETECTIVE CONAN OR MAGIC KAITO.

A/n: Apparently, Christmas mode has take control over my head although my country didn't celebrate the occasion. So, here's a short bonus chapter as Christmas gift for KaiShin shippers.

Advance Merry Christmas and Happy New Year, everyone.

"Kaito, what're you doing placing a pine tree in the middle of my living room?"

"It's for Christmas. Don't tell me you forget about Christmas?"

"…"

Kaito stopped rummaging through the boxes which contained Christmas decorations and turned around to look at his lover. "Oh my God, you forgot about Christmas? How could you? Did you even celebrate Christmas before?" He looked absolutely horrified at the thought of someone skipping the joyous day.

"Stop making a fuss. I did celebrate it last time, okay?"

Last time? "May I ask when is that last time, my dear meitantei?"

"Three- ah, no. Four years-" Shinichi's words were cut off when he got hit by a Christmas stocking straight at his face.

"Hey, what's that for?"

"No one skip Christmas. I tell you. No one."

"Ya, right. Very funny." Shinichi snorted at the obvious fake fact before he continued. "Well, it's not my fault that I missed four years of Christmas. I was accidentally stuck with a murder case last year, defeating BO the year previously, got kidnapped the year before that and accidentally got involved in criminal chasing.

"All that happened during Christmas?" Kaito's jaw dropped.

"Yes?" Shinichi smiled sheepishly while avoiding Kaito's gaze.

"You…you really are an epitome of bad luck." Kaito pointed his index finger accusingly at Shinichi before he pretended to do a dogeza. "Oh dark lord Shinichi-sama, please spares me from your curse of bad luck this year."

Shinichi rolled his eyes and said. "Stop acting like a kid, Kaito. We're almost 21 years old for goodness sake."

"Hehe, I'm a kid though. The infamous magician under the moonlight, Kaito Kid~" Kaito stood up and walked towards the pine tree to cover it with a piece of white cloth.

"And this magician will cast the greatest Christmas magic on you and everyone else for this year Christmas. Tada~" The pine tree was fully decorated when he removed the white cloth from it.

"Everyone?"

"We're going to invite everyone and have the greatest Christmas party ever." Kaito grinned as he changed into a Santa outfit in a blink of eye and grabbed Shinichi's hand. "Come on. Let's start preparing now. We have lots to do and there's only two days left to prepare."

"Since when I agree to have a party in my own house?"

"Since now."

Shinichi sighed. "Why did I ever fall for you again?"

"Because I'm gorgeous and smexy and you know it." Kaito grinned and placed a kiss on Shinichi's face.

"You're shameless."

Although the invitation for the party was given out late, everyone managed to turn up at the Christmas night in Shinichi's house. Yukiko, Yusaku, Chikage, Kogoro, Eri, Ran, Sera, Sonoko, Makoto, Haibara, professor, Aoko, Hakuba, Akako, Heiji, Kazuha, Jodie sensei, the police officers, even Akai came for the party. (also other characters which I'm too lazy to type)

The party was entertained by Kaito himself with occasional interruption from Akako's spells and Hakuba's snide teasing remarks on Kaito's magic which resulted in his hair getting dyed with rainbow colors.

The party was further entertained by the arrival of Inspector Nakamori and his Kid task force. Shinichi glared at Kaito when he heard the inspector's explanation. Apparently, Kaito Kid has sent him a notice that he would be here in Shinichi's house tonight to steal Kudo's family jewel (which is just something Kaito made up actually).

"Are you trying to destroy my house?" Shinichi whispered grumpily at Kaito who stood beside him.

"No. I just thought we need more entertainment." He whispered back and flashed him a Kaito Kid grin before snapping his finger and the light turned off.

When the light was back, Kaito Kid appeared at the top of the chandelier and started shooting paintballs at Kid task force and everyone else.

With that, a paintball fight started and at some point, turned into a food war and pillow fight. The adults merely enjoyed the shows and chatted with each other while occasionally joined the task force and the youngsters in those little wars.

It was two past midnight when all the guests finally took their leave.

"Now that everyone has gone back, I want my reward, Shinichi~" Kaito said after he sent his friends off and closed the main door.

"What rewards?"

"Reward for making this the best party ever."

"I gave you your Christmas present a few hours ago."

"Don't you think I deserved more?" Kaito took a step closer towards Shinichi and licked his lips suggestively.

Shinichi instinctively backed off.

"I don't think so. You made a mess in the whole living room."

"But, you also enjoy the party, aren't you? Plus, you know, I don't mind making another kind of mess~" Kaito smirked as he took another step forward.

"Stand where you are, Kaito. My parents are here tonight."

"Your room is soundproof."

"I have to go for a meeting tomorrow."

"That's the quirk of having a master of disguise as your boyfriend, don't you think? I can go for you tomorrow if you can't." A smug smile appeared on Kaito's face as he loomed over Shinichi whose back was against the wall.

"No- mphhh…."
