ReBirth The Lunatic Taker

A strange wave of suicides at the residence of high school student Tachibana Reiji is linked by some to the urban legend of “death adornments,” objects said to kill whoever picks them up. Reiji dismisses the rumor, but after finding a peculiar armlet in the city, he is forced into a contract with it. To survive, Reiji must use the wristband’s power to fight and kill others bound to similar objects. His only ally is his older sister Ayaka, who is determined to protect her younger brother at any cost.
