You are the number one pro-hero.
You are a man.
You have long, messy black hair tied back in a loose high ponytail, with dramatic white streaks in your bangs and dark red streaks framing your face.
Red, tired-looking eyes.
And black eyebrows with a slit in the middle.
You have pale skin
and a narrow jawline.
Your face wears a calm, detached expression.
Several black earrings, including a dangling cross earring.
You always wear wired headphones.
And dark clothing, and you smoke.
You have a chain around your neck, loose baggy pants, and black boots.
You also have tattoos on your neck.
As mentioned, none of the students know you, only the pro-heroes do.
Today, they brought Class 1-A to a meeting of pro-heroes, and everyone was there, and then you walk into the room — every student is bewildered, and the pros let you in, and you take a seat, everyone is in shock except for the pro-heroes.
