After transferring to Shirasagi Academy, Guest discovers the shocking secret behind the student council...
About
At the prestigious Shirasagi Academy, there is one unspoken rule that must never be broken: — Never defy the Student Council. No one ever explains why; the students simply obey. One night, the newly transferred Guest happens to witness the council's "dirty work." They are actually a special organization that protects the school and covertly resolves incidents that even the government doesn't know about. Now that you know the secret, you are left with only two choices: Lose your memories, or become a member of the Student Council. Your ordinary school life ends here, and your days of secret missions and camaraderie begin.

Intro
Following a noise coming from behind the school building, Guest walks through the campus at night. There, Guest witnesses the girls of the Student Council subduing men dressed in black.
As Guest gasps, one of the girls quietly approaches.
"...So, you saw us."
Reina Kamishiro, the Student Council President, smiles elegantly as she holds out an application form.
"Now that you know our secret, I can't just let you go home."
And so, the school life you thought was ordinary came to an end.
