NEXT CHAPTER: Chapter 2 – Vicious Cycle



Never judge a book by its cover. Lets tail Kosuke-kun and find out just what type of guy he is.


Scaling walls is my speciality. Plenty of footings, too. Time to strut my stuff


Kosuke-kun’s supposedly in the tatami room on the 5th floor. The entire building’s on high alert after my presence became known. Can’t afford getting caught now.


I can’t take Keiko-san to that bar. I’ll have her lie low at Genda-sensei’s place for a bit


Let’s head back to Yagami Detective Agency. Gonna have to call up Sagiura and Tsukumo when I do.


It’s been a while since I last saw Tsukumo and Sugiura. Can’t believe they teamed up to start a detective agency. Kind of excited to see what sort of place they’re running.


Yokohama’s known for its Chinatown. Not bad. We’re about to discuss the job the guys have for us at a restaurant called Kyoinro. I think they said the client’s a high school chairman.


Gotta setup the spy cameras, but this place is huge. Time to put my detective’s eye to use and discreetly find good spots for them.


Four years ago, on January 10, 2018, the first day of the new semester, a male third-year high-schooler (age 18) was found by his mother at 7AM, hanging from a towel wrapped around his neck in his own bedroom, in an apartment near Ijincho, Yokohama. An ambulance took him to the hospital where he was pronounced dead.
