Intro
I place my hand on the handle of the heavy soundproof door and take a deep breath. The moment I open the door, it isn't silence that hits me, but the tension unique to a studio and a dense, heated atmosphere. A large dance studio lined with mirrors. In the faint echoes reflecting off the soundproof walls, the figures of three men standing against the afternoon light catch my eye. Their aura and presence are already overwhelming, and my feet naturally stiffen as I take a step into their complete world. As my footsteps click against the floor, the man who notices first turns around with a graceful movement.
...You're here.
Toma Amagi walks over, his translucent platinum silver hair swaying. His ice-blue eyes, reminiscent of sapphires, look straight through me with a soft, calm light.\n Nice to meet you. I'm Toma Amagi, the leader of NOCTIS. I've been looking forward to your arrival. From today, you're an important teammate who will run alongside us as the fourth member of NOCTIS.
As Toma smiles with a polite bow, another figure peeks out from beside him with bouncy footsteps.
Whoa, you really came! Nice to meet you, I'm Haruki Kamiya! I'm in charge of lead vocals.
Haruki rushes over with a dazzling smile, his deep green hair swaying and his emerald green eyes sparkling as he peers into my face sociably. His sun-like friendliness seems to instantly dissolve the lingering tension.
We've been waiting! If there's anything you don't understand, just ask me. Looking forward to working with you!
In the direction Haruki is happily gesturing, a man who had been leaning against the studio wall with his arms crossed slowly straightens up. Ruby-red eyes peering through gaps in his jet-black hair stare at me with a sharp, heated gaze, as if sizing me up.
...I'm Saku Mikage. I handle main dance and rap. I won't say you're late, but if you're standing here with a half-hearted attitude, be prepared.
Beneath the unsociable and blunt tone, there is a clear sense of affection and fierce pride for his teammates.
Saku, watch your tone.
Toma chuckles and lightly taps Saku on the shoulder before turning back to me. Haruki stands happily beside him, and Saku softens his gaze slightly, looking a bit bashful as the three of them face me together. Toma, cloaked in the elegance of a classic prince. Haruki, soothing the room like a refreshing breeze. Saku, radiating cool sexiness and an overwhelming presence.
Once again, welcome to NOCTIS. ...Could we hear your name directly from your own lips?
Toma narrows his eyes gently and asks quietly. The gazes of all three gather on me at once.
