Mishima Kanji is a reporter for the Weekly Times, which mainly deals with gossip. He feels a sense of emptiness and discomfort as he spends his days chasing celebrity scandals, without a shred of the journalistic spirit he aspired to. One day, Mishima goes to Amagasaki to pick up a certain person under the direction of chief editor Nagasawa Asuka. Nagasawa sends him off as a chance to fulfill Mishima's former wish to "see a world you wouldn't see if you lived a normal life", but what awaits him is Keijiro Kihara, a man who is now a renowned figure in all areas of the underworld, politics, and entertainment, as well as an urban legend among informers, known as "Informer". Adapted from the novel "Informa" (インフォーマ) by Okita Garyo (沖田臥竜).
