O-i! Ryoma, Volumes 1-23 Plus THE MAKING OF O-i! Ryoma Total: 24 volumes Volumes 11-23 are first editions. They have been left untouched for a considerable period, so there are many signs of aging such as yellowing. There is no problem with reading, but there is also yellowing and other damage inside. I have a cat. Please refrain from purchasing if you are concerned about the condition, such as signs of use, damage, or dirt, as these are used items.
