Shiki Ichinose

Shiki is a curious girl who can be described only as "a mad scientist." She loves experiments, and is motivated by finding new things to hold her attention; if it's not interesting, she's not interested. Rather than being scouted by Producer, she chose him as part of one of her experiments. She sniffed the Producer and his smell convinced her that he was the right one for the experiment. She became an idol for this reason. (Source: iDOLM@STER Wikia)
