Can anyone outrun their past forever? Mirai Kuriyama's ability to control and manipulate her blood, even to use it as a weapon, has left her an outcast and pariah.

When the cost of that path becomes apparent, will the two of them be willing to pay the price for a true happy ending? Even if it's achieved, how long can it last in a world where Mirai's mere existence is seen as a lethal threat?
