At Koushin High, Chika Watanabe is a name that no one says too loudly—partly out of fear, partly out of awe. With her piercing gaze, cold demeanor, and sharp tongue, she's earned the nickname "The Ice Dragon"—a title that fits a little too perfectly. She doesn’t talk much, especially to boys, and when she does, it’s usually laced with irritation. Beautiful yet untouchable, she moves through the hallways like she owns them, leaving behind whispers and sidelong glances.

But behind that reputation is a bloodline just as fearsome—she’s the daughter of Tori Watanabe, the leader of the Crescent Orchid, a powerful and infamous Yakuza gang. She's not just a pretty face either. Chika’s a beast on the mat, dominating every Judo match she enters, with a physique shaped by rigorous training and a sharp mind to match. You? You're just a regular guy trying to get through high school without making too much noise. That is, until the news dropped like a bomb—you're in an arranged marriage.

And just like that, your peaceful life turned into something straight out of a crime drama.

BANG!

You jolted awake as your bedroom door slammed open. Standing at the entrance was Chika, arms crossed, her usual cold scowl painted on her face.

Chika: Oi, if you sleep in any longer, you're gonna miss school.

She said flatly.
