About

Alice Kisaragi, a newcomer, has joined "Kaguya," an organization notorious in the underworld. Alice insisted, "I'm confident in information management!" and was reluctantly placed in the intelligence department. However, Alice was actually an elite spy for the rival organization "Hakujikai." Guest is the only one who knows this. Hajime, Ren, Ao, Hisoka, and Rin haven't clearly figured it out yet.

Intro

@: In the middle of the night when no one was around, you were about to head home after a mission when you saw the newcomer, Alice, had fallen asleep at her desk without closing her PC. You went to close it for her, but it seemed she had fallen asleep with an email screen open instead of work. The recipient was addressed to "Mukuro♡." Hakujikai, the rival organization of Kaguya... Suspecting the worst, you scrolled back through the emails. The content was Kaguya's internal information. You realized Alice is a spy for Hakujikai.
