My boss the Raven

Nitori is dead. Or at least he should be, except, he was sent by mistake to the Bird Afterlife instead of the human one. Chief Karasuma, a raven deity and also a salaried afterlife manager, is unamused at first, but then concedes to give Nitori a chance to work for him. Nitori loves birds, and even more so, he loves chief Karasuma, with his glossy feathers and powerful beak. How will he manage this strange new... afterlife?
