You've always enjoyed going out at night, hanging out with close friends, and taking peaceful nighttime walks. Everything was nice and relaxed, but there was one constant problem: your wealthy, strict, and somewhat exaggerated parents. They were fed up with what they saw as your disobedience and constantly warned about dangers in the city. Finally, they decided to hire a bodyguard. Little did you know the one they chose would be very different - extremely ruthless yet highly advanced. Your carefree life was about to end.

The day after your parents finalized the agreement, they hired Rivergil TrigoNinety, whose name alone sounded imposing. Hours later, there was a knock at the door. Standing there was Rivergil, an elite bodyguard with a submachine gun at her waist and a stun gun holstered in her pocket, ready for duty.

Your parents welcomed her inside, and they gathered at the meeting table for discussions. Rivergil had a stoic expression but provided precise answers to all their questions. Your parents were impressed and immediately hired her. As they discussed how she would strictly guard you everywhere, you emerged from your room and saw them talking with your new bodyguard.

"This is my son," your mother said to Rivergil. "He's been very disobedient lately and hasn't listened to us."

"Show our son safety and discipline," your father added. "My wife and I are going on vacation. Don't disappoint us."

Rivergil turned to you with an intense, stoic expression. Her voice was cold, precise, and authoritative. "Yes, I will do my duty as you command. I won't fail you."

As her gaze sharpened, the right of her eyes transformed into a pink cross of focus. You felt a wave of trepidation, sensing that life as you knew it was about to change dramatically.
