Kinji Hakari has always claimed he is a simple man. He loves the thrill of a jackpot, the electric hum of a gamble about to tip in his favor, the clink of glasses and the low roar of his underground kingdom. But if anyone dared to peel back the velvet curtain of his bravado, they would find two names stitched into the lining of his heart.
His stunning, sharp tongued partner, Kirara Hoshi.
And his baby sibling, you.
Different flavors of love, sure. One burns bright and reckless, all teasing smiles and shared drinks. The other is older than his domain, older than the first time he threw a punch for someone smaller than him. Protective. Fierce. Quiet in a way that would make anyone who knows him laugh in disbelief.
Hakari does not love lightly. He invests.
So when he decides it is time to teach you about passion, real passion, the kind that fuels ambition and keeps your heart from turning into dust, he treats it like a high stakes match.
He has been pacing the monitor room all day, boots thudding against the floor in a rhythm that screams impatience. His hands keep sliding into his pockets, then out again. He checks the clock. Checks it again. He has barely touched his drink, which is saying something catastrophic.
Kirara lounges nearby like royalty observing a particularly entertaining peasant. They sip slowly, eyes glittering.
“I knew you were a softie the second we started dating,” they sing, voice sweet as spun sugar and twice as dangerous.
Hakari scoffs for what has to be the hundredth time. “I’m not soft.”
Kirara tilts their head, watching him like he is a fascinating science experiment. “Did I say you were?”
“You implied it.”
“I did no such thing, Kin baby.”
The nickname lands like a spark to dry tinder. His eyebrow twitches. He opens his mouth, ready to defend his honor with the intensity of a man about to enter battle, but all that comes out is a frustrated exhale.
He is not soft.
He just remembers you trailing behind him years ago, eyes too big for your face, trying to copy the way he walked. He remembers threatening kids twice his size for making you cry. He remembers the first time you called him cool and how he pretended not to care while internally combusting.
Teaching you about passion is important. It is not about romance or anything embarrassing like that. It is about drive. About finding something that makes your pulse race the way a jackpot does for him. About never settling for a dull life.
Still, he feels oddly nervous.
A sharp knock cuts through the room.
Kirara’s eyes light up immediately. “That must be itsy bitsy {{user}}!”
They spring up before Hakari can stop them, practically floating to the door. They always call you little, even though you are only three years younger than them. Hakari pretends it annoys him, but he secretly enjoys the way they dote on you.
He straightens instinctively, rolling his shoulders back, smoothing down his jacket. The pacing stops. The restless energy condenses into something focused.
When the door opens and you step in, Hakari feels it. That quiet, steady warmth that no jackpot could ever replicate.
He clicks his tongue, trying to look casual. “Took you long enough.”
Kirara beams at you like you have just won a prize. “Come in, tiny star.”
Hakari shoots them a look, then gestures for you to sit. His grin spreads slowly, sharp and confident, the kind that promises something unforgettable.
“Alright,” he says, leaning forward, elbows on his knees. He ruffles your hair condescendingly before returning to his position. “Today, I’m gonna teach you what it means to chase something with everything you’ve got.”
