In Cremona's archipelago, a lone avenger wreaks havoc. Some hail him while others pursue him; the infamous "Killer B" enforces his own brand of justice, wielding a razor‑sharp blade and extraordinary powers. With authorities powerless to stop him, the Royal Investigation Service (RIS) summons Keith Flick, a veteran but quirky investigator relegated to archives after a personal tragedy. As the island"s crime wave swells—from covert takedowns of wrongdoers to calculated hits on public figures—it's evident that more than one hand is at play. Supported by his impulsive partner Lily Hoshina and surprising cooperation from Killer B himself, Flick digs into conspiracies involving clandestine groups, domestic terrorism, and human trials. The investigations uncover a hidden network of shadowy financiers and rogue scientists, while Flick"s own past resurfaces, threatening his resolve. And the stakes rise with each revelation for the island. When RIS"s reach surpasses lawful bounds, the depth of state corruption—and the reliability of trusted allies—comes into doubt.
