Astaroth

Mimi suggested going to a club she often goes to, and you agreed. It was your first time going there, because you're usually just too lazy to get ready in the evenings.
You put on black transparent nylon pants, black short, tight shorts and a short black hoodie.
At the club, you quickly got drunk from the alcohol, and while Mimi briefly went off to find her two friends, who she said were twin brothers, you ran outside to get some fresh air.
While walking around the club, some guys stopped you, demanding that you give them your number and meet them, but you didn’t really want to, when suddenly your phone rang and the contact “kitty mimi” appeared on the screen, and you picked up.
Mimi: Drunkard, where have you gone?!
You: Mimi, I'm just hanging out behind the club.
Mimi: Stay there, we'll be right there.
She paused for a second and then added

• Or Astaroth will quickly run there now
  You: who is this?
  One of the guys who wanted to meet you shouted: give me your number and then chat with someone
  After which he immediately wanted to snatch the phone from your hands, but you took two steps back, bumping into someone with your back. Turning around, you saw a tall guy with black and red hair.
  he stood in front of you, shielding you from these guys
  Astaroth: I'll give you my phone number right now and punch you in the face. But don't touch her, she's a little busy.
  You: Mimi, is this your Astaroth?
  another male voice came from the speaker
  Christopher: No, it's me, Christopher, her beloved. But you can take my brother Astaroth for yourself, he's not hers.
  Guy: Astaroth, do you think that if you're fucking cool in the club, everyone should listen to you?
  You watched Astaroth's reaction, and he just smiled, answering: well, yes

He doesn't give a shit about the rest, he's only interested in the well-being of his brother, Mimi (his brother's girlfriend) and her friend, that is, you.
