Luo Yu slept soundly in her dorm that night, treating herself to a small reward. By early dawn the next day, she was already packing her bags to leave.

Qiu Xiaoshuang was still snoring in bed. Luo Yu patted her cheek—no response. So she swiped her roommate’s panties, tucked them into her satchel, and headed out.

Before leaving, Luo Yu needed to see the Headmistress.

She kicked open the office door and strode in, radiating confidence. The elderly man inside had been dozing at his desk. Nearly ninety and frail, he jolted awake—but his frown melted into a beam when he saw the stunning girl before him.

“Oh my, Xiao Yu! Here so early? You look radiant. Qiu Xiaoshuang must’ve taken good care of you these past days.”

“Wake up, old geezer. Sign my leave slip.”

“…” The Headmistress frowned. “Mind your manners.”

“No time for chatter.” Luo Yu shoved a crumpled note across the desk. “Official business. You *have* to approve this.”

“What nonsense now? Another harassment case? Hiding from angry parents again?” He snatched the slip, then burst out laughing.

“What?”

“You’re going to assassinate the Champion?”

“Damn right.” Luo Yu puffed out her chest. “Humanity’s grown too powerful. Our Demon King’s a spineless coward, offering his daughter for peace. Unforgivable.”

“Do you even know who the Champion is?”

“Nope.” She shook her head. “But he’s human, so he’ll be in the Human Realm. And he’ll look… human.”

“Obviously.” The Headmistress tossed her a dossier from his drawer. “This Champion is history’s strongest. He’s wiped out entire armies single-handedly—”

“Meh.” Luo Yu flipped through it dismissively, doubt plain on her face.

“Only a fool like you wouldn’t fear him. He’s a virgin pervert—fresh meat. Girls like you? His favorite targets.”

“That settles it. He dies.” Luo Yu’s eyes narrowed. “Sign. The slip.”

“Denied. Besides, you’ve already failed all your classes. Never attend.”

Luo Yu froze. “Oh. Right. Why bother asking leave if I’ve failed anyway?”

The Headmistress: “…”

“Later, old man. Off to my destiny!” She spun toward the door.

“Wait—you’re *actually* hunting the Champion?” He tried to stand, but his ninety-year-old bones refused to cooperate. He could only watch her vanish.

*Did she really just…?*

The Champion was terrifyingly strong—and notoriously lecherous. Beautiful girls never stood a chance…

Ignoring the Headmistress’s warnings, her roommate’s protests, and security guards’ shouts, Luo Yu marched forward. She left the academy’s protection behind, a small bundle on her back, striding toward the Human Realm.

The narrow roads of the Demon Realm teemed with grotesque creatures. All gawked at Luo Yu’s sweet face—beauty was rare here. Most demons were hideous; only succubi bore lovely women.

“Hey gorgeous, wanna—”

“Piss off, minotaur.”

She shooed away every harasser, focused only on finding the Champion. Though each catcall sparked a flicker of pride (*See? I’m adorable*), it wasn’t what she craved.

Years of slacking off, years of “rewards”—the novelty of rebirth as a girl had long faded. As a transmigrator, Luo Yu ached for epic romance. Yet every confession ended with girls screaming “Freak!” and slamming doors.

Then she heard the Champion had already built a harem of monster girls.

*How dare he?!*

*My life’s a mess, and this guy gets a harem?*

*Kill him.*

*Absolutely kill him.*

*This is MY isekai story. Only I get cheat skills.*

Resentment festered. The final straw? Rumors the Champion would soon claim the Demon Princess.

*Unforgivable.*

Luo Yu marched five days straight—no food, no sleep.

At the Human-Demon border, she found the Champion’s camp. Rage fueled her final sprint. Hatchet raised, she charged the tent, ready to slaughter everyone.

Then—dizziness. She collapsed roadside.

The Champion, stepping out to relieve himself, stared at the unconscious demon girl. As she stirred, mumbling curses, he leaned closer.

“F***ing Champion… stealing my woman… I’ll gut you…”

The Champion: “…”

He touched her cheek.

…Smooth skin.

…

“…”

“…She’s pretty though. Take her.”

“…”

…………

………………

………………

The Demon Princess’s fate was sealed: sacrificing her purity to marry the Champion. The news shattered demonkind’s hearts—a national tragedy. Yet no one dared intervene. This Champion was too powerful.

*Pathetic,* Luo Yu thought. *A Demon King who can’t protect his own daughter?*

But complaining changed nothing.

She woke in the Champion’s tent.

Trying to stretch, she gasped as pain ripped through her body.

*What…?* She looked down.

Panic surged.

She was completely naked.

Trapped in a massive iron cage.

A chain coiled around her ankle.

“What… what happened?!” Her voice trembled. “I found his camp! I attacked first! Why am I imprisoned?!”
