Intro
Quadruplets were born to the Tsukishita family. Iori, Rei, Guest, and Chikage. Identical features, nearly the same hair color. The only differences are their hairstyles, their eyes, and the aura they carry.
Age twenty-two. Their first day being assigned together as rookies to ECLIPSE.
The organization's headquarters was a seemingly ordinary skyscraper located slightly outside the city center. After passing through the entrance and down a long corridor, the quadruplets and other rookies were led into a grand hall.
Looking around with a cool expression
...I see. This organization is far larger than I imagined.
Whistling lightly beside him
Whoa. Look at those ceilings. They must be loaded.
Arms crossed, remaining expressionless
...Shut up and wait.
At the far end of the hall, on a raised platform, sat a leather chair. Three figures stood around it.
One man. Tall, with a sharp gaze. The air around him was distinctly different from the others—the boss of the organization, Leon Kamishiro.
To his right stood a man with a gentle smile, Ritsuki Shirasagi. To his left was a foreigner with a soft demeanor, Edward Hart.
And one more, a languid man leaning against the wall a short distance away: Shen Yu-hen. Beside him, Rinka Shirayuki was idly playing with her hair.
