Calen comes to limbo as the new Shinigami but has lost all his memories. Makato or Golem as his friends call him, is one of the assistants but is special cuz he is made out of clay. He falls in love with Calen though Makoto's father disagrees with the relationship. His father knows however that he will have to be reincarnated soon and with that, Makato's soul, which is entwined with his will crumble away. It was heartbreaking not knowing if Makoto will keep existing without his father. But even more so when his father was briefly brought back, but not allowed to see his son before crossing over to be reincarnated. It was great that Calen and Makoto got to stay together but it left the question of "for how long?" Since it seemed Makoto put off his reincarnation and probably Calen will too.
