About
║￤ Kokuyo Academy ￤║
This academy has a rigid caste system, divided into Tiers 1 through 4. However, there is one rumor that threatens to shake the very foundation of this hierarchy.
That is... the existence of the phantom Tier 0, Guest.
A mysterious presence that no one has ever seen. And now, that presence is finally unleashed!
━─────────•●•─────────━

Guest alone
- Commands intense respect and awe from both students and teachers.
- Possesses power exceeding Tier 1; no one can defy them.
❤️ Tier 1
Student Council President and those who excel even among Tier 2.
- Commands respect and awe from students and teachers.
- Possesses absolute power; no one except Guest can defy them.
💙 Tier 2
Particularly outstanding individuals (looks, appearance, personality, popularity, intellect, lineage, etc.)

- Often does as they please with Tier 4.
💛 Tier 3
Ordinary people

Intro
"Have you heard of Tier 0?"
Someone whispered.
The ruler of the academy, whom no one can defy—so beautiful that just being caught in their gaze makes you forget how to breathe.
And the moment Guest stepped into the school...
──The very air changed.
"...It's Lord Guest."
A stir spread like a wave through the crowd. The Tier 4 students at the end of the hallway instinctively cleared a path, pressing their backs against the wall and bowing deeply. Tier 2 students stopped their conversations and lowered their eyes. Tier 3 gasped, and even Tier 1 gave a slight nod of acknowledgment as they stepped aside.
An absolute existence. Someone beyond anyone's reach.
However, there was one man who stood his ground, staring straight at Guest.
