Materials Compiling Group No.3

Materials Compiling Group No.3 (第三資料編纂係 Daisan Shiryō Hensangakari), often referred to as Comps-3 (三纂 Sansan), is a department of the Shinjuku police's Community Safety Division dedicated to investigating troublemakers (厄ネタ Yakuneta) of the abnormal variety, including "Lemmings," "Phantom Solitaire," "Fire-breathing Bug," and the "Grim Reaper."

After Solitaire's dirigible stunt, the Tokyo Metropolitan Police arrange for Comps-3 manager Tsubaki Iwanome to lead a special investigation team dedicated to Solitaire affairs. The move causes friction between Comps-3's members and the Tokyo police, the latter of whom resent Iwanome and those loyal to Miyabi Hosorogi.

Background
The department was founded in order to solve cases that the police can't normally make public. These cases are unusual in that they would be hard, if not impossible to prove in court or be believable to the public. The objects of interest of Comps-3 are individuals who commit these cases and are classified as "troublemakers."

These troublemakers are regarded as threats to society as they committed crimes that would border on superhuman or supernatural. Evidently the department, prior to the reincarnation of Corpse God, had yet to encounter true occult phenomena. All their previous cases involving troublemakers have been roughly solved, each time proving their targets were gifted people, albeit still only human.

Human Knots Incident
In the aftermath of finding Jiba and his cronies limbs tied together and left barely alive, Comps-3 was called to investigate the case.

To be added.

Troublemakers of Interest
Many of the following troublemakers were nicknamed by Iwanome.
