This is a complete 3-volume set of Maya Koikeda's "My Younger Sister is an Akita": * "The Fateful Encounter Arc" * "The Troubled Beginner Arc" * "The Lively Event Arc" The back cover of "The Fateful Encounter Arc" has an illustration with a signature (photo 4). (I purchased this used, and the name of the original purchaser is written in the part I covered with my finger.) I apologize, but I will not sell the volumes separately. Thank you for your understanding. Thank you very much!
