“Omen Desu” (It's a Mask) * Title: Omen Desu (It's a Mask) * Author: Koji Ishikawa * Publisher: Kaiseisha * Price: 1,100 yen + tax I haven't read it much, so it's clean and in good condition overall. However, there is a small tear when opening one of the pages. The cover is included. Please see the photos.
