Kusakabe Sakura is visited one day by a mysterious angel. Some might see this as a blessing, but for Sakura’s life becomes a living hell. Not only is Dokuro lazy and a freeloader, she is also violent and somewhat delusional. Offend her, and she’ll club you to death with her spiked bat Excalibolg. Unfortunately for Sakura, she has a kind heart and will restore him to life each time he meets his grizzly end – only so he can repeat the whole cycle of pain at a later time.
