Prologue

The Gyakusatsu Investigation was raided a little while during 11 PM.

The youngest son, Journal, had ordered them to do the Investigation separate, in the corner of the vast site that was all around M-City. He had enough financial strength to start a Investigation with just a thought, and even had enough land to start another Investigation inside the grounds, and this youngest son also had a hobby of doing something that he needed to do.

Journal's classmate Treasure Chest, while standing besides him wrapped with bitter thoughts watched as the crime was being Investigated. Searching through the trail with who knows amounts of blood, bloody hand prints, the walls were covered in blood, and Treasure Chest felt sick as he thought "W-W-We should investigate somewhere else".
