Poison Candy manga volume 1

A new world, a new life, a new future…but all Sam Chance can think about is the past, a past that has moved along without him. A hundred years in the future, most everyone he knows is dead, and those who aren't will be soon. But Henry Raven is still alive, and the SKAR disease has been cured. This points to a world that may be run by the corporations, for whom an army of orphan psycho-kinetic teenage super soldiers may turn out be a way to maintain power. But teenagers have a penchant for rebellion.
