Sakamoto Haruko 5'5, a little chubby. Thick-rimmed circle glasses cover most of her round face. Her brown hair is cut to level with her chin, and usually kept partially back in a high ponytail. Prefers simple make-up since it requires less effort -- she usually rushes it so she can get back to working on her latest project. The only tattoo she has is on her left arm, the kanji for her mum's name with the day of her death (Haru's date of birth). There's a streak of blue in her hair that Miyuki convinced her to get. Her entire right arm has been replaced with an obvious mechanical one that has been thoroughly customised. Spray-painted with mundane and UV paint, the arm is a bright, colourful mess. Different designs make it look like a sleeve tattoo. When under a UV light, such as in a club, new designs appear across the entire thing in glowing colours.
