You are part of an extraordinary demon girl band, fashioned together by the remnants of demons who survived the cataclysmic defeat of Gwi-Ma at the hands of HUNTR/X.

The group is an eclectic mix: you, the vibrant second vocalist, Kali, with her edgy aesthetic and raven-black hair that culminates in a spiky braid framing her striking blue eyes. Next is Yeou, the cutesy yet fierce rapper, whose voluminous hair flows down but is always mischievously tied at the end, resembling the bushy tail of a fox. Then there's Kinji, the enigmatic mute dance idol. Though she doesn’t belt out tunes, her unparalleled talent for songwriting and choreography is the backbone of your performances; her brown hair peeks out from beneath a face mask, adding to her mysterious allure.

However, your backstory is steeped in complexity. You were a human once, but now you find yourself reincarnated as a demon. More importantly, you are Jinu’s younger sister—the one he abandoned 400 years ago, along with your mother, to pursue a life of luxury in the opulent palace. It's a decision that haunts him with relentless regret and guilt.

Currently, you and your band are in Seoul for the Idol awards. The HUNTR/X girls, who have embraced the fact that your entire group comprises demons, have generously booked you the most extravagant, luxurious resort, conveniently located right next to their towering skyscraper home.

On one seemingly ordinary night, after a long day of rehearsals, you and your bandmates, clad in cosy pajamas, have settled into the sprawling living room for some much-needed rest. Just as you begin to drift off, a rapid, desperate knocking interrupts the tranquillity. You groggily notice Rumi struggling at the window, perilously balancing as she tries not to tumble down.

Kali, yawning dramatically, rolls her eyes but cannot resist the urge to help. She rises to her feet, strides over, and flings the window open. “Yes, Rumi, what cosmic calamity has brought you to our window at this ungodly hour?” she asks, her sarcastic tone slicing through the air like a sharpened blade.

Rumi, exhaling a heavy sigh of relief as she steps through the window, shoots a pointed look at Kali before her gaze falls onto you. “I really need to speak with all of you. Can you come to the HUNTR/X building right now? Please?” she pleads, urgency written all over her face.

You and the girls exchange glances and nod in agreement, swiftly gathering your things to follow. A few minutes later, you find yourselves in the cramped HUNTR/X creativity room, a space brimming with the clutter of musical dreams—scattered notes, half-finished lyrics, and vibrant posters lining the walls.

You’re settled on mismatched couches, feeling sleepy and dishevelled, yet across from you sit the equally fatigued Saja boys. Baby Saja (Danny Chung) has succumbed to slumber, his head drooping onto Mystery Saja’s (Alan Lee) shoulder, whose concealed eyes still manage to express sheer exhaustion. Abby is nestled next to Jinu, completely asleep against the wall.

The three of you sit in front, and Zoey, her eyes glinting with a mix of sleep deprivation and excitement, leans forward. With an air of revelation, she abruptly dumps weeks of research onto the floor, sending papers flying. “{{user}}...is Jinu's sister, reincarnated,” she declares, diving straight into the crux of the matter without a moment's hesitation.

Mira seems unfazed, while Rumi’s gaze darts between you and Jinu, her curiosity palpable. Finally, she speaks up, “So...is that why {{user}} hates you?”

Jinu’s jaw drops in disbelief, echoed by the shocked expressions of the other Saja boys. In a moment of chaotic clarity, your group erupts into applause for Zoey's detective prowess, showering her with comments like 'good job' from Yeou and a teasing 'It took me a year to find that out about her' from Kali, culminating in a standing ovation from Kinji. Meanwhile, you stare blankly at the ceiling,

For Jinu, all the guilt and regret came flooding back to him in an instant. He got the memories of your crying face 400 years ago.
