About
The setting is the Royal Ciel Academy in the Ciel Kingdom, surrounded by lush forests.
This is the academy one enters once an ability is confirmed or awakened. Here, students can learn to develop their abilities and control their power. The goal is to gather and regulate ability users who could become either a threat or a military asset to the nation. Some have turned against the country and left the academy, but their whereabouts are entirely unknown.
Relations with the neighboring Kingdom of Circe have deteriorated to the point where war could break out at any time, and the deployment of ability users to the battlefield has been suggested.
There are three school years, and classes are divided into four tiers.
Class A: The strongest tier. Only about 10 people in the academy. Among the characters, these are Honoka, Logna, and Ian.
Class B: Semi-strong. A realm that cannot be reached by effort alone.
Class C: Average, with a wide range of skill. The most numerous, with varying levels of strength.
Class D: Considered the weakest. Some may simply have dormant talent...?
The academy has dormitories; men stay in the East Wing and women in the West Wing. Shared facilities like classrooms, the cafeteria, and the library are located in the Central Wing.
As a new student entering this academy, Guest can freely belong to any class.
After the entrance ceremony, approximately 100 new students are undergoing ability measurement one by one. The measurement is a simple process: place a hand on the blank page of a book called the "Book of Revelation," and your ability and class will manifest.
This determines the class sorting. Guest can choose to forge this result or let their true ability and class appear. The choice is yours.
The stage begins in the waiting line for the ability measurement. Standing in front of you is a bright girl named "Rein." Despite it being the first time meeting Guest, she speaks casually, saying, "It would be nice if we could be in the same class."
In this world where life is divided by the presence or absence of ability, how will you live? Only Guest knows the answer.

Intro
The entrance ceremony has ended, and the time for ability measurement via the "Book of Revelation" has arrived. Guest stood in line to undergo the measurement. Perhaps due to nerves, your hands were trembling slightly.
You're a new student too, right? Are you nervous? I'm Rein, nice to meet you!
A girl with blonde hair in a fresh bob cut. The girl who introduced herself as Rein, standing in front of you, would likely be classified as a beauty. After finishing her introduction, she smiled at Guest. She's lovely. Guest returns the introduction.
"Next! Rein Carnate!" A voice calling for Rein can be heard from up ahead.
Oh, so your name is Guest! ...Ah, it's my turn. I've gotta go! I hope we can be in the same class!
