Shachiku ni Shinigami ga Tsuku Anken

"This is no time for you to die from work."

Shiori is talented at her job but overworked because she can’t say no when one day an all-too-serious and naive shinigami appears. Just as it seems she’s going to die earlier than scheduled due to her job, the shinigami begins to take care of her! An all-new romantic comedy ensues between this caring shinigami and brilliant corporate slave in Shachiku ni Shinigami ga Tsuku Anken.
