Jakyo: Akisato Wakoku - Complete 5-volume set. This is a story about assassins called "Jakyo" who use the principles of Kijutsu (a form of divination) to kill people. "Jakyo" is the secret business of the Senju family, and the protagonist is the 62nd head of the family. It was interesting. I also learned a lot because I was studying Kijutsu. Some volumes have sun damage, but overall, they are in good condition. Thank you.
