Fandom: Detective Conan
Summary: There were only three kids of the Akai Family, right? There was no way that Masumi had a third older brother. So why the hell were these people calling him Akai Mitsuharu? More importantly, how the hell was he even alive!? [OC Insert as Akai Sibling]


"Children, meet your new classmate Haibara Ai," Kobayashi announced. "Be nice to her. Now where will you be sitting?"

"Next to me, Sensei!" Genta called. "The seat's vacant,"

Haibara ignored him and walked over to the empty seat beside Conan's desk. "Hi,"

"Oh, uh, hi?" Conan seemed surprise at her personality. 'What's with her?'

Once class ended, Ayumi caught up to Haibara. "Haibara-san, let's go home together!"

Haibara paused for a second and then just continued walking. "Don't bother," Genta said. "She's just a stuck up kid,"

Ayumi and Mitsuhiko both walked on either side of Haibara. "Where do you live?" Mitsuhiko inquired. "You just moved here, right?"

"Don't be shy with us," Ayumi added. "We'll walk you home,"

"222B Beika Street," Haibara answered. "That's where I live now,"

"Huh?" Conan put his hand to his chin in a thinking pose. 'Weird, that's near my house. But there are no apartments nearby or anybody called Haibara,'

'Hmm, he didn't notice that it's Professor Agasa's house,' Haibara noted. 'Haru was right. He can be a bit dull at times,'

Haibara was invited to join the Detective Boys. She accompanied them to question their client whose older brother had disappeared.

'It's already dark,' Haru noted. 'Haibara's not back yet. Are they caught up in a case?' He took out his pair of tracking glasses. 'It's a good thing I'm able to track Conan's glasses down with my own,'

After a few minutes of driving around he came near a police station. He caught sight of Conan running into the building next to it. 'Why are they in the building near the police station? Geez, those Detective Boys are always going places they shouldn't be. The same goes for Conan. He's acting way too overconfident. What would he do if he was surrounded by multiple people with guns? He only has one tranquilizer dart, power enhancing shoes, and one soccer ball at a time,'

He parked his motorcycle and followed Conan's trail. As Conan reached for the doorknob, a man pointed a gun at him from behind. Haru's eyes narrowed and he used his wristwatch to tranquilize the man, catching him before he fell as to not cause a loud noise. "Shh," He held up a finger to signal Conan to keep silent. He took out his own handgun.

"Conan-kun, help!" Ayumi cried out from the other side of the door.

"You mean that four eyed brat wandering by the stairs? Too bad he's already dead," The lady prepared to shoot her.

Conan kicked the unconscious man's gun which collided with the woman's, causing both to clatter to the floor. Conan used his tranquilizer to put the woman to sleep. Haru pointed his gun at the two men. "Don't move!"

"Heh, you've got guts threatening us while we're the ones with hostages," The injured man said.

"Oh, I'm just the distraction," Before any of them could make a move, Conan had taken out two paint cans and kicked them. Each paint can crashed into a man's face and freed the children. "Is everyone alright?" Haru asked. 'Ran and the kids' parents are probably worried sick,' "Go get the police; I'll stay here and make sure these guys don't escape,"

Conan and Haru were both accompanying Haibara home. "APTX 4869," Haibara spoke towards Conan. "That's the name of the drug they forced you to take,"

"What are you talking about?" Conan asked. "I've never swallowed a drug with such a weird name, right Haru-niichan?"

"That's the name of the drug that I created on the organization's order," Haibara revealed.

"You invented? The organization?" Conan started to sweat nervously. "Come on, how can a kid like you—"

"That drug was meant to kill without a trace. But rather than killing you, you reverted to a child," Haibara glared at Conan. "My codename is Sherry. Are you surprised, Kudo Shinichi?"

"Haibara, stop scaring him," Haru scolded.

"Haru you told her!?" Conan exclaimed.

"What she said was the truth," Haru informed. "She's a former member of the organization that shrunk you as well as the one who invented the drug Apoptoxin 4869. Look, can we head inside first? I don't want the neighbors overhearing,"

It was a tense walk to their destination, which to Conan's shock, was Professor Agasa's house. "Why's she living with the professor!?"

"Because he has a lab and your house doesn't?" Haru shrugged as they entered.

"You have a lot to explain!" It was Conan's turn to glare at them. "Why's a member of the Black Organization living here!?"

"Professor Agasa adopted me," Haibara answered. "Haru was the one who found me passed out in front of your house. Didn't you know that the organization sent investigation teams to your house twice when Haru wasn't around? There were signs that the people living in the home was mourning someone and your room had a layer of dust. Once I noticed that your childhood clothes were missing, I knew that you had shrunk. I marked your data as deceased since it's rare for a specimen to shrink,"

"How do I know that you're not going to tell the organization?" Conan interrogated.

"She betrayed them," Haru answered. "She never wanted to work for them but she had been born into it. She developed the drug against her will, her sister being held hostage,"

"I was tired of being a prisoner and halted the drug's research. For rebelling, I was locked in a room," Haibara continued. "I took APTX 4869, intending to commit suicide. Instead, I ended up shrinking so I escaped through a small laundry chute,"

"What about your sister?" Conan pointed out. "You said she was held hostage,"

"The FBI replaced her with a look alike two years ago," Haibara explained. "The only reason I hadn't committed suicide back then was because I was holding onto stupid hope, hope that I would also be free like her,"

Conan brought Professor Agasa and Haru to another room. "Do you think we should trust her? She could be lying about her entire backstory,"

"She isn't," Haru knelt down to Conan's height. "I know because I was the one that told the FBI to get her sister out when she found out she was pregnant. Her sister is my brother's girlfriend," He looked in the direction of the other room. "I made a promise to Akemi that I'd protect Shiho," He then looked down at Conan. "Besides, she's the best chance you got at making an antidote,"


So Haibara's met Conan. It's pretty much the same in canon except Haru helped bring down the counterfeit company. He didn't remember that the Detective Boys would encounter the Silver Fox group and was just worried that Haibara hadn't come home yet.

I created another story, Mitsuharu Shorts and What-Ifs, if you're interested on reading. The shorts are canon to the Mitsuharu storyline while the What-Ifs are AUs.
So far there are three chapters: What if Gin fell in love with Haru?
What if Kaito Kid fell in love with Haru? and Lupin III VS Detective Haru—I mean Conan!

I do plan on doing Darkest Nightmare. I was going to going add it to the movie list in the previous author's note but kinda forgot.

Oh, and as for Cognac's age? Probably somewhere in his twenties. I'm feeling twenty two to twenty five years old. His face will be shown in due time.

Same announcement from Mitsuharu Shorts and What-Ifs Chapter 2:
