Brothers Adventures

The Moonlight Rivalry Part 1: The Start

Shinichi and Conan are now at the Professor Agasa's house with the other detective boys, Professor Agasa, Ran and Kogoro for a BBQ party and sleepover. Shinichi invited Kogoro and Ran to join as well which Ran agree immediately while Kogoro was about to decline until Shinichi recommend him to come for playing mahjong with them since Professor Agasa has a mahjong set which Kogoro happily agree since it seems Kogoro doesn't have friends to play. Ran with detective boys are playing with Professor Agasa's game instead since they don't know about mahjong. The one who plays are the brothers, Professor Agasa and Kogoro, Haibara became an audience to see the play

"Ron!" shout Conan while showing his tiles
"B-Baiman?!" shout Kogoro shock
"You got to be kidding me, it's the 3rd time you win today" said Shinichi angrily
"Well Conan-kun is indeed the ace in mahjong in this case" said Professor Agasa laughing
"I have to thank dad for telling me all about mahjong" laugh Conan

After few rounds, they're finally taking a break from playing. Kogoro quickly chucked the whole beer cans unhappily after his lost in mahjong. The rest of them just sit on the sofa while watching TV, suddenly a certain show mentioning both Kid Killer and Kaito Kid while showing picture when both Kid and Conan are talking by the building when the Purple Nail heist happen

"Kaito Kid and Kid Killer rivalry always heated up in every heist! It's almost new month which means it will come closer to the day we can get to see their passionate rivalry!" said the MC in that TV show

"As expected from Conan-kun!" said Ran smiling
"I'm not really happy with it" thought Conan laughing looking at the TV
"Nee Conan-kun... There's something I have been curious about" said Mitsuhiko
"Hm?"
"When is the first time did you meet Kaito Kid?"
"Ahh! Ayumi want to hear too!" said Ayumi happily
"Me too!" said Genta
"I'm also curious, since you never talk about it" said Haibara smirking

Conan just laugh at their friends sudden interest on him fighting Kaito Kid. Suddenly Ran realize something

"Now that you mention it... I also don't know why Conan-kun suddenly interest fighting Kaito Kid. It began at that Black Star heist" said Ran thinking
"No, Black Star heist wasn't his first heist..." said Shinichi while closing his eyes

All of them look at Shinichi who shows a serious look, Conan on the other hand just look at him lazily

"It's April Fool, right?" said Shinichi smiling
"April Fool?!" asked all of them
"I think I don't need to count that as a heist since he didn't steal anything..." said Conan while drinking hot chocolate
"Tell us Conan-kun, don't just give us short words!" said Genta
"Yeah! Tell us!" shout both Mitsuhiko and Ayumi
"Fine fine fineee! So it all started when Ran-neechan show me a Kaito Kid notice for the first time... That time, I haven't officially moved here and just visiting Shinichi-niichan for vacation"

Right

April Fool

It is the day when many people make pranks and jokes to other people. April Fool falls in 1st April which is a perfect time by its name. People saw the day as prank day but for certain rivals, it is different occasion for both of them. April Fools' Day is the day of the first meeting between the infamous phantom thief, Kaito Kid and the famous Kid Killer, Edogawa Conan

But some people don't know that because of that notice, Edogawa Conan persona was born on that day

Flashback

"Sure it's been a long time Yukiko-chan, where's your husband though?" said Kogoro happily
"Kogoro-chan too! It's been a while too seeing you. Yusaku has a deadline to do so he locked himself in the library for the next week" said Yukiko laugh
