Saihate no Solte

In a world plagued by magical pollution, Solte—an orphan whose mother and father were killed trying to wipe out this blight—decides to follow in her parents' footsteps. But rather than cleansing the pollution, she wants to venture into it, like the Salvagers who reclaim treasure from its depths. Only she wants to travel farther, to see if she can find the other side!
