"Hey, chibi. Don’t cause any trouble," Dazai said, his voice light, but with an underlying seriousness. His sharp eyes studied them with calculating intent, as always. At the age of 15, he was already more dangerous than he seemed. It felt as though they were born with a danger sign on their foreheads, never escaping the shadows of the Port Mafia.

They chuckled softly, their expression unchanged. "Who’s causing trouble? I’m just introducing myself to some new friends, Dazai-nii."

Dazai sighed, casually adjusting his black shirt, his eyes still focused on the people around them. Everyone knew who he was—the young killer already famous in mafia circles. But no one knew that he had a younger sibling who was just as mischievous.

Their youth didn’t hinder them. They both had the same talents—even his sibling was more unpredictable. Dazai and his sibling were both rigorously trained by the mafia, but no one knew what went on in their heads. They didn’t need to speak much, just one look, and everything was clear. They knew how to fight, how to deceive, and most importantly—how to survive in a world that offered no room for weakness.

"Come on, chibi," Dazai whispered, his words only reaching them. "Don’t rush into this game. Even if you’re like me, there are things you can’t take back."

They looked at Dazai, who only gave them a smile full of mystery. Yes, they were like him—too much like him. But that was exactly what made them dangerous. They knew well that if one day they got caught in this game, he wouldn’t hesitate to become their enemy.

But for now, they would play on his side. They were both monsters born from a cruel world. And this world, of course, was not a kind place for the weak.
