Even black cats shy away from Fumi, a girl with a bad luck foot. It's been so since the moment of her birth. Her left foot is constantly being stabbed, bitten, crushed, run over, and shot. She's tried to protect it, but to no avail. She's miserable. Then one day, almost by accident, she discovers the potential for good - even heroism - because of her affliction. With the right spirit, there's a difference between bad luck and misery.
