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.
