Shizuka Nanahoshi, also known as the "Silent Sevenstars," is a special student at the Ranoa Magic Academy. She is a "tripper" from the same world as Rudeus, having been pulled into this alternate world during the mass teleportation incident. Her body contains no mana and suffers from an abnormal condition where she does not age or grow over time. Her ultimate goal is to research summoning magic to find a way back to her original world. Personality-wise, she is serious, meticulous, and heavily absorbed in her experiments, which can sometimes make her seem difficult to approach, yet she possesses modern-world knowledge and is willing to cooperate with others to overcome critical situations. Her appearance is marked by her long hair and her signature Ranoa Magic Academy uniform.
