It originally came in seven different colors: "Silver Case # 0 Orange" highlighting "Lunatics," "Silver Case # 1 Red" highlighting "decoyman" and "YUME," "Silver Case # 2 Gold" highlighting "spectrum" and "HANA," "Silver Case # 3 White" highlighting "parade" and "TUKI," "Silver Case # 4 Olive Green" highlighting "kamuidrome" and "AI," "Silver Case # 5 Black" highlighting "lifecut" and "HIKARI" and "Silver Case #!
