This is a set of volumes 1-5 of "Mystery wo Iu Nakare" (Don't Call It Mystery) by Yumi Tamura, published by Shogakukan. I have read them once and am now selling them as I no longer need them. They have been stored on a bookshelf out of direct sunlight, so there is no sun fading or dirt. However, please refrain from purchasing if you are sensitive to items that have been stored by an amateur. Immediate purchase OK. Price negotiation NOT accepted.
