Ibuki Keita lost his mom as a child. It happened one day after she met a person who looked just like her. So now Keita can't help but think that the legend about doppelgenger is true: in this world there are 3 people who have the same face. If you meet them, you'll die.
Now he sees his mom's doppelgenger again, and people arround him die one after another, the day after they met a copy of themselfs.

Then he meets a strange girl Kuro, and her dog Puni-Puni. She clears him up about the legend: in this world there are only doppel-liner. It's a system to protect the Terra. There are 3 people who look the same, and share destiny. If you meet one, you'll go against the rules and cause of an accident, illnes, or some other reason will be terminated.
Before Keita can ask more a strange guy attacks the girl with a baseball bat... and the girl stands up again! It turns out she is a Mototsumitama, who has enhanced healing ability, and great stregth.

First as I saw some pictures, I thought 'this will be just like Shakugan no Shana', only the girl has a dog, and not a cat... well it seems to become true. How I got from the preview fo the second episode, Kuro will share something with Keita, and so begin a contract-kinda thing with him. Well, I'll see how far they are going, but the fact, that they use 'kami' in the anime after the girls name, and her hair is NOT black, it's quite clear who will win at the end... no matter who the enermy is. u.u"
