Mary Akai and Tsutomu Akai had to admit that they were really worried about their younger child. Senichi had been born twelve minutes after Shuichi. He had been a loud baby at birth and was screaming as if he were in extreme pain. He thrashed around and wouldn't stay still in his parents' arms. It was only after he was exhausted did he finally quiet down and fall asleep.

But when he woke up, Senichi was quiet. He looked around the hospital room, taking in the details of the room. "Senichi?" Mary gently called. Of course Senichi didn't acknowledge her voice. He didn't understand that Senichi was his name yet. After all, he had been born just yesterday. "Tsutomu, I think something's wrong with Sen,"

Tsutomu carefully took the younger twin from Mary. "Hi there Sen. I'm your papa. That woman there is your mama and the little boy is your older twin brother, Shuichi,"

Senichi's blue eyes were filled with sorrow and pain. As he looked between the three people, confusion and shock were added to the mix. "Wah?" He frowned and licked at his toothless gums. Without teeth, he would have a hard time speaking coherently.

"We're your family," Tsutomu said. "Your name is Senichi, Sen for short,"

"Wo!" Senichi yelled in response and shook his head, as if he were refusing to be called by that name. He angrily pushed at Tsutomu's chest and pounded at the man's arms. "Wo! Wo! Wo!"

Unknown to Mary and Tsutomu, Senichi was not a normal child. Physically, people would perceive him as a normal blonde haired and blue eyed baby. Mentally, he was actually seventeen years old. Before he had been reborn as Senichi Akai, he was Michael Leo Field, an American teenager of Filipino descent, and a weebtaku. He was especially a big fan of Detective Conan.

In the Real World, he had come home from school only to be met with the sight of his house engulfed by an angry blaze. He had ran inside in an attempt to rescue his parents, ignoring the shouts of the firefighters that were attempting to extinguish the inferno. When he found his parents, it had been too late. Their corpses had been burnt to a crisp and the flesh was starting to melt from the bone, dripping as if it were water from an icicle in a desert. Their expressions were filled with horror, pain, and agony. Their mouths were wide open, having been screaming for help with their last breaths.

They were forever engraved in Michael's mind. He had been devastated at the discovery and had fallen to his knees. Even if he wanted to escape, falling debris had blocked his escape routes, trapping him with his parents' corpses. When the adrenaline started to wear off, he began to feel the intense heat and shrieked. The fresh scream pierced through the flames and was heard by the crowd of neighbors that had gathered at the scene. The flames around him roared wilder and circled around Michael like a hellish tornado.

After Michael had perished and Senichi was born, he still couldn't shake off the feeling of the flames biting at him, hence why he was screaming and squirming at birth. He hadn't registered that he had been reborn and was now a baby. It wasn't until he had fallen asleep and woken up did he finally realize what was going on. He didn't understand how the hell it was possible, but he had been reborn as Senichi Akai.

When Tsutomu had introduced himself and the others, claiming to be his family, Senichi was in denial. He screamed out "No!" though it came out as "Wo!" He didn't want to accept that his parents had died, that they were truly gone. He didn't want to accept that he had been reborn. He didn't want Tsutomu or Mary or Shuichi. He wanted Marinette Field and Adrien Field. He didn't want this new life. He didn't want a life without his parents.

Two days after Mary had given birth, Shuichi and Senichi were finally taken to their new home. Despite the fact that Senichi rejected his new life, his body had given in to drinking milk to survive. He may be seventeen mentally, but physical he was a newborn child. He didn't have as much stamina as a teenager and took several naps throughout the day. His days consisted of eating, sleeping, bathing, and playing.

The couple had purchased a developmental mat for Shuichi and Senichi. While Shuichi, being an actual child, was amused by it, Senichi was bored and uninterested, instead opting to stare out the closed window's glass, engrossed with his thoughts. 'Why was I given another life? Were Mom and Dad also reborn in this world? If so, did they fall in love again? Shouldn't I be reborn to them? There's nobody named Senichi Akai in canon. Why was I reborn as Akai's twin brother? It doesn't make sense,' Senichi curled up into a tight ball, tears falling. 'It's not fair…'

Shuichi stopped playing and crawled over to Senichi, wrapping his arms around his twin and giving him a hug. "Ah?" Even though he was only a few weeks old, Shuichi was already acting like a big brother and comforting the younger boy.

"Senichi, please don't be sad," Mary and Tsutomu knelt down beside the two babies. This was the first time since the day of his birth that Senichi cried.

'I want to go home…'

After a few months, Senichi finally came into terms that he would be stuck in his situation. He tried to continue on living as a baby, but it was just so hard. He kept trying to be thankful that he was given a second chance at life, but the survivor's guilt was eating away at him. Some days he imagined himself falling from a high place and smashing his head to the ground. If he died, would he move on to Afterlife and reunite with his parents? Or would he just be reborn into another world?

Senichi frantically shook those thoughts away. 'Mom and Dad would be happy for me! They'd want me to live a happy life!' That's what he kept telling himself, but the dark thoughts kept on coming back from time to time.

On some days, Senichi would just mope around. Other days, he'd try to fulfill his role as a child. There were times when he was excessively sleepy and fatigued, yet insomniac. Sometimes he had a large appetite while other times he had no appetite at all. He forced himself to consume at least the bare minimum amount of milk to keep his stomach from growling and to live on to the next day.

Mary and Tsutomu, who were still pretty new to parenting, tried to keep Senichi's mind occupied, presenting him with a variety of toys and giving him and Shuichi lots of attention. Senichi didn't care for the toys and pushed them all towards baby Shuu who gladly accepted them. It was only when Senichi managed to find the box of art supplies that Mary and Tsutomu were going to let the twins play with when they were older did Senichi actually do something different.

By six months old, Senichi had managed to regain some motor skills. He was able to walk around for a while before falling onto the carpeted floor. His parents were overjoyed that he had learned to walk at such a young age. From what they've read on the internet, babies tended to take their first steps between nine and twelve months. Senichi managed to pick up and carry lightweight objects but had the most control over his writing and drawing skills, hence why he had decided to go after the pencil and paper in the art supplies.

Mary held Shuichi in her arms as she and Tsutomu watched Senichi draw. Drawing was Senichi's coping mechanism. He didn't have access to any manga but he did use his memories as references. The younger twin drew a pencil sketch of an adult Akai Shuichi. He didn't really know what else to draw and he was in the Detective Conan World. Besides, it wasn't like they would be able to tell that it was Shuichi in thirty something years.

The thing he hadn't taken into account was the quality of his work. Senichi's sketch did not look like it was done by a six month old. In fact, it looked like it was done by someone much older, which was kinda true since he was mentally seventeen but nobody knew that. The parents hung the drawing up on the refrigerator as where all childhood artworks would be presented on as if it were a museum display. The parents were quite impressed by the drawing but parenthood combined with work was very tiring and many things slipped by the exhausted parents' minds, hence why they didn't really question Senichi's skill.

Six months old was also the earliest age where babies tended to say their first words. Shuichi's first word was "Mama" and his second word was "Dada." Mary was overjoyed. Tsutomu was also happy, though he was a teensy bit jealous. This prompted him to urge Senichi to call him "Papa." Senichi had tended to stay silent, not wanting to humiliate himself by babbling nonsense. Although he kept track of the date and time, he had little to knowledge of babies. He was growing annoyed by Tsutomu's continual insistence. Apparently they counted his first attempts at saying "no" when he was born as baby gibberish.

Senichi looked at Tsutomu straight in the eyes and grinned mischievously. "Shiwba buwwet,"

Tsutomu was silent for a few moments before he started to panic. Honestly, Senichi was certain that Shukichi got his carefree side from Tsutomu. "MARY!" Tsutomu stumbled into the bedroom where his wife had just finished changing Shuichi's diaper.

"Tsutomu, not so loud!" Mary scolded.

"Dada," Shuichi called towards the man.

"Oh my gosh, Shuu-chan you are so cute!" Tsutomu cooed before shaking his head. "Mary, Sen-chan just said his first and second words!"

"You look like you're conflicted between happiness and worry," Mary noted.

"Mama?" Senichi waddled into the room with an innocent expression.

Mary glared at Tsutomu. "You left Senichi alone in the living room!? He's already up and walking! What if he got hurt!?"

"I—" Tsutomu sighed and picked Senichi up. "Sorry, I panicked,"

"What's wrong?" Mary asked, this time her tone gentler. "It's not like you to act like this,"

"Sen's first words were silver bullet," Tsutomu answered. "I know for a fact that we never mentioned alcohol around him and Shuu,"

"Maybe he meant the silver bullet that kills werewolves," Mary brought up. "We sometimes talked about movies and books we've read while the babies are with us,"

"Y-Yeah," Tsutomu nodded and scratched the back of his head. "You're probably right. I'm overthinking it,"

"By the way," Mary smirked. "He called me 'mama' when he came into the room,"

"No!" Tsutomu groaned in defeat. "They both said 'mama' before 'papa!'"

Eventually, Shuichi started walking at about a year old. Unlike Senichi who took precise steps to a certain destination, Shuichi would wander around the entire house, intending to explore every nook and cranny. "Sen!" Shuichi tugged on his younger twin's arm. "We go!"

'It's a miracle that I've managed to not go insane after all this time,' Senichi thought as he gave in and followed Shuichi around the house under Mary's protective supervision. He was silent except for his footsteps and the sounds of him sipping his juice box. 'Now I know why Conan struggles to keep his intelligence in check, especially during cases. This is such a pain in the ass,'

Although he hated being treated like a child, he was thankful that Mary and Tsutomu cared for him. If he had been reborn to neglectful or abusive parents, he would have most likely died a horrible death. He was a teenager mentally but physically he was too weak to protect himself. It had taken him a while to accept Mary and Tsutomu as his new parents, to understand that Marinette and Adrien were still his parents and that he still had room in his heart for another set of parents as well as siblings.

This is my first Rated M story, mostly for the depictions of violence and gore I plan to include. It's a much darker OC Insert. Looking back at Mitsuharu, I realized that I didn't really give Haru much time to mourn his parents' deaths. He was just like "WTF, I just died!? Now I'm in the DC World!? Okay, let's just roll with it! Yeah, my parents just died, but I have new ones!"

This story is not related to the Kidnapped or Taken WIVerse in Mitsuharu Shorts and What-Ifs. Senichi will have a different personality from Haru. They are completely different characters that just happen to both be reincarnates of Michael Leo Field.

Everything is in western order and the language being spoken is English because this story takes place in England. Tsutomu just uses chan in a cutesy manner to address his children. When the story shifts to Japan, the names will be in eastern order and there will be more honorifics used.

Arc I will be focused on Senichi's childhood and will be Rated K+ to T. Arc II and III is when things start to get darker and Rated T to M.
