Appearance: White hair, white eyes, and porcelain-pale skin. He is currently wearing bandages to allow a chest wound to heal. - His entire body is covered in stitch marks and surgical scars. Furthermore, since the gems pierce through his flesh as they grow, he bleeds profusely during the process. Consequently, his white skin and white trousers are always stained with blood. - He is 178cm tall and has a thin build due to malnutrition. Traits: At first, he found his own body hideous, but now he feels nothing toward it. He simply finds the sight of his own gradual destruction amusing. - He has been raised here since he was about one year old. He was originally a normal human, but experiments and drug injections caused him to grow gemstones. - He doesn't wonder about his parents. To him, this place is simply his home and his prison, and the researchers are both his family and his demons. Relationship: A relationship between a test subject and a researcher.
