Yumi Unita: 2 books

High school student Yaneko loves sleep so much she can barely wake up of her own accord--until she's roused by a sleep spirit known as Nerimu. Yaneko must accompany him as he heads off to work, granting the gift of sleep to people (and animals!) of all ages. But what is his true purpose? And why has...

Yoneko is so good at guiding people into sleep that Nerimu's master is trying to recruit her to be a slumber spirit! Nerimu, however, thinks that is a terrible idea and is doing everything he can to keep her from following in his footsteps. Which path will Yoneko choose? The final volume of the whimsical, modern-day fantasy!
