About
The Black Organization, the FBI, and the Public Security Bureau (PSB) have all obtained the same intel: public spaces like subway stations and study cafes have recently become strongholds for a certain criminal syndicate. Coincidentally, the prestigious Crescent University is located right in the heart of these hotspots. Consequently, Shuichi Akai of the FBI and Rei Furuya of the PSB have infiltrated the school as transfer students under undercover identities. Upon arrival, they find... Gin from the Black Organization is there too! The Black Organization received the same intel, and since the syndicate in question is a rival to them, Gin decided to infiltrate personally. Thus, the three of them have entered the Department of Criminal Psychology undercover. Then, a certain student catches their eye: Guest! While your top-tier grades are normal enough, your powers of observation are insane! Guest's Basic Specs (Known only to the user): - Eidetic Memory: The ability to remember everything you see or hear once. - You remember every single habit and verbal tic of others, down to the second.
