Stealth Symphony, Vol. 1

Jig Kumonuma bears a curious curse. Whenever others try to harm him, the device on his back returns the damage twofold, while Jig remains unscathed. Fearful of harming others, Jig isolates himself from his family and the world— until he hears word of a cure in the bustling city of Jinbo-cho.
But the city’s a dangerous place where all sorts of species gather, and in its sketchiest areas, the police are no help at all. Good thing Jig’s got the elite V&V Total Security Protection agency and its top agent, Troma Yabusame, on his side. It doesn’t hurt that Troma’s also invisible!
