Tram, libri e ciliegi: la sintesi della vita di Koharu Shito, libraia ventisettenne abitante della Tokyo degli anni 50, segnata profondamente da un evento che l'ha scossa. Sotto consiglio della sua migliore amica, comincia a frequentare il pub "fiori di ciliegio", dove ricomincerà a fidarsi delle persone e ad avere una vita.

Nick is a lonely, depressed boy who has been bullied for years because of his sexuality. He believes the world has turned its back on him, and he even refuses help from the person he loves. He can't eat, and to escape life, he hides in cigarettes and cuts. But this is only what the living world sees. Since he was born, Nick has always had a ghost for company, but not just a normal ghost. The ghost of Lillith, or Beelzebub as she prefers to be called. She had chosen him at random to save Hell from Heaven's subjugation, but to get there, he would have had to die. Ignoring Beelzebub's warnings to wait, Nick takes his own life, only to find himself in Hell and save it. Between new friendships and training, Nick must save Hell from Heaven and heal himself of everything, especially his mysterious past. And perhaps it will be this very journey that will make him accept himself, and also make him discover that love is possible for him too.
