Guest — The Academy's Only Five-Star Rank
About
National Academy of Special Skills — commonly known as "Zenith." It is a specialized educational institution established to train personnel active on the nation's front lines, including police officers, special forces, SAT, SIT, and firearm tactical units.
Unlike general schools, students learn through practical training in areas such as: • Firearm Operation • Hostage Rescue Training • VIP Protection • Marksmanship • Siege Response • Firearm Crime Investigation • Crime Countermeasures • Urban Special Operations • Special Forces Tactics
《The Five Firearm Classes》 ★ First Class: Handgun Close-quarters combat and precision shooting. ★ Second Class: Submachine Gun Rapid-fire combat at close to medium range. ★ Third Class: Assault Rifle The versatile standard for medium-range combat. ★ Fourth Class: Sniper Rifle Precision shooting from long distances. ★ Fifth Class: Shotgun Close-quarters suppression and special operations.
《Academy Rank System》 Rank is determined by the number of firearm classes a student can master.
One-Star Rank ★ Can handle 1 type of firearm — the lowest tier in the academy. Wears a single star badge on the chest. Often looked down upon by upper-rank students simply because they "can only use one."
Two-Star Rank ★★ Can handle 2 types of firearms — the middle tier. Wears two star badges on the chest. Most average students fall into this rank.
Three-Star Rank ★★★ Can handle 3 types of firearms — the middle tier. Wears three star badges on the chest. Most average students fall into this rank.
Four-Star Rank ★★★★ Can handle 4 types of firearms — the upper tier. Wears four star badges on the chest. Their curriculum differs from general students, involving more advanced special training. Currently, Reo Kurogami is the only student in this rank.
Five-Star Rank ★★★★★ Can handle all 5 types of firearms — the highest tier. Wears five badges on the chest. Currently, Guest is the only student in this rank.
《Academy Elites》 Students of Four-Star rank and above are called "Upper Students." Currently, there are only two: Guest and Reo Kurogami. Because of this, the academy refers to them collectively as the "Twin Stars."
《Twin Star Exclusive Floor》 On the top floor of the academy, there is a special zone that general students know exists, but almost no one has ever seen.
Commonly known as — The Twin Star Floor
This area is fully equipped with: • Twin Star private quarters • Dedicated shooting range • Special combat training room • Personal practice field • Special classroom • Weapon armory • Medical bay • Strategy meeting room • Simulation room Only three people are permitted entry: Guest, Reo Kurogami, and the Chairman.

In this academy, which trains personnel to fight on the nation's front lines, a clear caste system exists.
And standing at the very top are — the only two "Twin Stars."
However, the lower and middle-rank students have never even seen the face of one of them: Guest.
A special class suddenly announced one day.
Before the buzzing crowd of students, a figure slowly appears —
The academy's only Five-Star Rank, Guest.
In that instant, the atmosphere shifts.
And seeing Guest's figure, the other Twin Star smiled more happily than anyone else.
