Owara Nai Chinkonka wo Utaou: Seinen no Uta

Kota has become a shinigami and his job is to follow a man at the end of his ropes. Slowly Kota learns about the man's life and what led him to this point. NOTE TO MODS: sorry I messed up the prequel's title. Could you change "Owaranai" to "Owara Nai" so it matches this entry. Thanks!
