Yurigami-sama no Iutoori!

Eri Anzai, a cheerful and energetic gal, dies after falling down a flight of stairs. In the afterlife, she meets Polero, a yuri-obsessed grim reaper, who offers to bring her back to life—on one condition! "Get together with the girl you love!" Eri's crush is Fumi Seike, a high-spec young lady from her school. But Eri was always too embarrassed to even talk to her... To help Eri out, Polero assigns her a series of "missions" to being them closer together, but the missions turn out to be a bit too bold and daring...!? (Source: Takeshobo, translated)
