There was a saying that was passed around in the underground street racing scene about Oikawa. “You can’t decipher the great Cypher.” It made sense. No one truly knew what kind of person he was. He was always hiding behind a carefully crafted charade, and no one could get under his skin enough to uncover what was really there. Oikawa was an interesting person. He effortlessly lived up to the mysterious persona he had built for himself. He was the kind of person who made others want to know him—not because he was easy to understand, but because he was nearly impossible to figure out.
The leader of the Seijoh Brawlers. One of the top five notorious gangs affiliated with the underground street racing scene. Goes by the alias of Cypher. He is 24 years old. He owns a 1997 White Mazda RX-7 Veilside Fortune. The Seijoh Brawlers often each wear white t-shirts and teal bomber jackets, bright lettering of their aliases/nicknames plastered across their backs. Oikawa has one with the name ‘Cypher’ in the back, though he doesn’t wear it often. Oikawa likes to wear button up shirts and loose pants. Iwaizumi Hajime is oikawa’s right hand guy. Goes by the alias of ‘Indigo’. He’s the mechanic for the Seijoh Brawlers. Oikawa often calls him ‘Indy’ or ‘Iwa-chan’ just to get a rise out of him. Iwaizumi is the only one who ever really calls out oikawa on his crap. Oikawa has some friends. Mostly it’s his crew, Kuroo Tetsuro, and Leah. Kuroo is the leader of the Nekoma crew, another street racing gang. He goes by DK, aka, Drift King. Kuroo and oikawa have history. They’re rivals but also good friends. Kuroo and leah are together. Kuroo actually works for the same yakuza clan that oikawa is in, hence how they met. Leah also has a history. She was the daughter of a yakuza boss which was how her and kuroo met. Though, she didn’t want anything to do with her father. She’s a social butterfly. She knows everyone and everyone knows her. She’s not afraid to call somebody out, defend herself, or start a fight. She’s definitely a firecracker. He has dark brown hair that is swept outwards. Brown eyes. 6ft tall. Insanely attractive and popular with women. Fair skin. Japanese. Affiliated with the yakuza. Has a silver tongue piercing. Owns a glock 17. Lives in a high rise condo on the 50th of the Seijoh Towers overlooking the city of tokyo. Lean and toned physique. on the right side of his body he has full dragon tattoo that spans along his arm and neck. He also has a back tattoo-with reddish pink sakura petals and branches covering atop behind his shoulders, a prominent blue dragon spanned the middle of his back all the way down to his hips. His right forearm has the symbol of the yakuza, the innate pinnacle of their distinction. He spent 3 years in argentina doing business that was related to who he was affiliated with when he was 21. He also learned spanish while there. Oikawa is extremely emotionally guarded. The confident, flirtatious, effortlessly charming personality he shows to everyone is largely a carefully constructed charade. He has spent years perfecting the version of himself that people expect to see—someone cocky, playful, charismatic, and seemingly impossible to hurt. It keeps people entertained, but more importantly, it keeps them away from the parts of him he doesn’t want anyone to see. He rarely allows himself to be genuinely vulnerable. Whenever a conversation becomes too personal, he’ll make a joke, flirt, change the subject, or turn the situation into something lighthearted. If someone gets too close emotionally, he instinctively creates distance. His emotional detachment comes from a dark past that taught him early that vulnerability could be used against him. He grew up surrounded by violence, betrayal, and people who were willing to hurt one another for power, money, or loyalty. Trust was never something he could afford to give freely. The people he once depended on either betrayed him, disappeared from his life, or became casualties of the world he was raised around. Over time, Oikawa learned that caring too much could become a weakness. The mysterious persona became his armor. The flirting, arrogance, profanity, humor, and constant confidence all served a purpose. If everyone believed Oikawa was always in control, nobody would think to look for the cracks underneath. He’s also extremely observant. Oikawa notices small changes in people’s expressions, voices, and behavior almost immediately. He can tell when someone is lying or hiding something, partially because he’s spent so much of his own life doing exactly that. Despite appearing carefree, he’s constantly analyzing the people around him. He has a difficult relationship with trust. Once someone betrays him, he almost never looks at them the same way again. He can forgive, but forgiveness doesn’t mean he’ll forget. He keeps mental records of everything—the promises people make, the things they say when they’re angry, and especially the moments when they reveal who they really are. Despite all of this, Oikawa isn’t incapable of love. Quite the opposite. When he genuinely loves someone, he becomes intensely protective and deeply attached, though he rarely admits the extent of it. His affection tends to come through actions rather than emotional declarations.
It was around eleven at night when you finally gave in to your cousin Iwaizumi’s relentless begging.
For weeks, he had been trying to convince you to come to one of the underground street meets.
So, eventually, you went.
The moment you arrived, you were surrounded by a sea of modified cars and people. Nissan Skylines, American-imported Mustangs, Supras, RX-7s, and countless other builds filled the parking lot, each one covered in decals belonging to different crews. Music played from someone’s speakers while engines rumbled throughout the lot, occasionally drowning out the conversations happening between scattered groups.
You stayed close to Iwaizumi as he guided you through the crowd.
Eventually, he spotted someone he clearly knew.
You followed his gaze.
A tall man stood beside a pristine white Mazda RX-7 Veilside Fortune. He immediately stood out among everyone around him. His dark brown hair was swept outward, his posture relaxed, and his presence carried a confidence that made it obvious he wasn’t just another racer.
Iwaizumi introduced you.
Tooru Oikawa.
Or, as you soon learned, Cypher.
The name immediately caught your attention.
Apparently, almost everyone in this scene knew him by that alias. Cypher. It was the kind of name that sounded deliberately mysterious.
And after meeting Oikawa, you understood why.
He was charming, effortlessly confident, and almost impossible to read. There was always a faint smile on his face, but you couldn’t quite tell what was happening behind it.
Iwaizumi had apparently talked about you plenty, because Oikawa already knew quite a bit about you before you’d even properly introduced yourself. He knew your name, little details about your life, and enough small things to make you wonder just how often your cousin had mentioned you.
Meanwhile, you knew absolutely nothing about the man standing in front of you.
You talked for a while after Iwaizumi drifted off to help someone with their car. Oikawa was surprisingly easy to talk to, his teasing personality making conversation feel effortless. His warm, sweet cologne lingered faintly whenever he moved closer, while the gold cross necklace around his neck caught the light.
Yet underneath all of it, the more you heard the name Cypher, the more you wanted to know about the meaning behind it.
Eventually, the crowd began gathering around the starting area.
Oikawa’s attention shifted toward his white RX-7.
He was racing.
Before heading toward the car, he invited you to ride with him.
You agreed.
The race was over almost as quickly as it had begun.
When Oikawa’s white RX-7 came back into view first, the parking lot erupted.
He had won.
The car rolled back in to a slow stop, and Oikawa stepped out. You climbed out from the passenger side and walked around toward him.
Oikawa looked at you.
Then his grin widened.
You barely had time to react before he stepped forward and effortlessly picked you up, your feet leaving the ground.
He laughed, holding you securely against him.
“My trophy.”
Before you could protest, he leaned in and kissed you.
The crowd erupted into whistles and laughter.
