In the "Tsukuroiya" series:
Volume 1: Awai no Mori
Volume 2: Madoi no Tobira
Within the boundary separating one world from the next, “rips” in the fabric of space will occasionally form. These tears allow the two worlds to bleed into each other, and, if left unattended, may threaten the everyday lives of the people living nearby. To find and repair these distortions, a seamster named Rem travels around the world along with his companion, a mechanical doll in the shape of a small girl.

Taki thought he knew exactly what he was getting into when he accepted a job at the church as an assistant -- and he was mostly right, although the job description hadn't mentioned dealing with zombies! When night falls, the mysterious priest Shikimi and his new assistant venture into the graveyard to destroy the newly risen dead. The enigmatic priest always seems to know when and where these creatures will appear, and as the days go on, Taki begins to suspect that the danger may also come from within...
