I'm also DC and MK fan so this fanfic is for them. I'll update my other fics when I have a new idea, so please bear with me.

Summary: Conan and the rest of the gang are invited to visit a client's mansion and so happen to meet Kuroba Kaito there. Will the both of them be able to keep their identities from each other? Especially when a case comes up!

"Shadow Manor?" The shrunken detective questioned raising an eyebrow as he studied the letter.

The so called famous detective's eyes twitched. "MIND YOUR OWN BUSINESS, BRAT!" He yelled and whacked Conan on the head.

"Otou-san!" Ran shouted as she rub the bump that appeared on Conan's head.

"I'm okay, Ran-neechan." Conan said in a cute voice trying not to scowl. He looked back at the letter that was sent to the old man this morning. It was out in a black envelope and a red seal.

"Fancy rich bastards…" Kogorou had mumbled under his breath as Ran handed him the envelope and he tossed it aside.

"Otou-san, aren't you going to read it?" Ran said in a stern voice.

"They can wait! Yoko-chan is on TV!" He yelled hugging the TV.

"Yoko-san can wait! What if it's a client in trouble?" Ran said with half moon eyes.

"If they were, they would have come here personally, why send a letter?" Mouri tried to argue. Ran was still standing there with the same expression.

"Fine…fine…geez….can't get a break around here at all…." Mouri grumbled and picked up the envelope and tore it open. Conan sneaked up behind him and read along.

Dear Mouri Kogorou-san,

Sorry for the inconvenience, but I would like to invite you to our Shadow Manor. We heard about your skills and want to invite you to our mansion as our special guest. We are having a party in honor of our father's birthday this Friday. Be sure to bring your friends.

From

The Kazuki Family

"Shadow Manor? " Mouri yelled. "What kind of name is that?" He mumbled afterwards.

"Can we go, otou-san, please can we go?" Ran pleaded.

"Hmmmm…..there might be good wine there…..and pretty ladies…hehehe…OKAY!" Kogorou laughed in his idiotic way. Conan and Ran sighed.

Friday….

"Why do I have to bring you guys…?" Kogorou said with a scowl.

"Come on, old man! What harm can we do?" Heji said with a huge grin.

"Besides, if I come, my little follower has to come too!" Heji said patting Kazuha on the back.

"Who said I was your follower, you are my follower, ahou!" Kazuha yelled smacking Heji on the back of his head.

"Ow, you're the ahou!" Heji yelled back. They continued bickering in their Osaka accent, ignoring all the confused stares they got from bystanders. Conan rolled his eyes. Haibara smiled. "Just like you and Ran, ne Kudo-kun?" She whispered so only he could hear. Conan gave her look. She chuckled quietly.

"Don't worry, Mouri-ojisan! The Detective Boys are going to solve any case we run into!" Ayumi, Genta and Mitsuhiko yelled.

"Don't worry ojisan! The Suzuki Family and the Kazuki family are in great terms, so they won't mind me!" Sonoko said with a grin.

"Sorry….for bothering you guys." Agasa said with a smile.

"Enough talking! Let's just go!" Mouri said with a growl and got into his rented van.

Hattori slowly move closer to Conan.

"Oi Kudo, do you have any idea why they called you guys to their party and why they said to bring friends?" He whispered.

"I don't know…but I have a bad feeling about this…" Conan narrowed his eyes as they drove off.

Do you like it? I don't know how to write in a Osaka accent so I'll write normally for Heji and Kazuha. Please review!
