A valuable complete manga set by Yu Koyama. Ai ga Yuku: Volumes 1-12 Sprinter: Volumes 1-14 Change: Volumes 1-5 Kaze no Saburo: Volumes 1-4 Ganbare Genki: Volumes 1-28 There is some yellowing due to aging, but it was kept as a collection and I received it from someone, so it's in relatively good condition for its age. Ganbare Genki has book covers, not just fading. However, volume 8 has a split in the book.
