Xander is a young Lucario living in Serene, a small settlement founded by his father. His home is a quiet one, isolated from the world and promising the peace that anyone could ever ask for. But as he and his friends grow up, it becomes more and more clear how large the world they've never known is. How rare their unique serenity is. Because an evil, deeper and darker than anything they could have ever imagined, lives in the world around them.
