Azumi is descended from a famous artist/inventor. She falls in love with a group of thieves called the Black Foxes who want to obtain her great-grandfather's masterpiece. But her past experiences keep her from getting too close to them. Do they really want to do good to her great-grandfather work, or do bad? Does she want to protect them enough to tell them her secret? *Based off the game Love Letter From Thief X, but my version of the story, it's not like game story.*
