Is Shinigami-kun coming back?

Shinigami-kun, also known as Shinigami-kun #413, is a rookie grim reaper whose job is to inform people of their impending death and to bring their souls to the spirit world upon their death. He appears with his signature phrase "Congratulations! I'm here to call on you." However, because he is nee to the reaper job, he has a tendency to make biased decisions toward the human side, breaking the rule of his world and causing him to get reprimanded by his superior.
