Ark by Haruo Yugi Ichijigen no Sashiki (One-Dimensional Grafting) by Ryunosuke Matsushita Two paperback books set. Ark was purchased yesterday and read once with the cover on, so it's very clean. Ichijigen no Sashiki was purchased in July and stored at home. The covers will be removed before shipping. I am not considering price reductions or selling the books separately. Please understand that these are used items stored at home before purchasing.
