Mikage is a supporting character who appears in the third episode of Mushishi Zoku Shou 2nd Season, the second half of the series that follows the journey of the mushishi Ginko. She is introduced as the wife of a man named Youkichi. Her background is defined by a mysterious and unsettling incident: she appeared in a village without any memories shortly after a young girl named Akane vanished from the same area. This coincidence links her fate to the strange circumstances surrounding Akane's disappearance, an event that occurred when Akane encountered a shadow without a caster at dusk and was never seen again. Mikage's role in the story is that of a person caught in the wake of a mushi-related phenomenon, and her presence serves as the catalyst for the episode's investigation. Her personality is not extensively detailed, but her situation suggests a quiet, disoriented individual grappling with a complete loss of personal history. Her motivations are not explicitly stated, though her primary drive is likely a passive search for identity and understanding, as she must live with the gap in her memory. Her key relationship is with Youkichi, her husband, who presumably took her in or married her after her mysterious appearance. She does not display any notable abilities of her own; her significance comes from being a human element affected by the unseen forces that Ginko studies. Development is limited due to her brief appearance, but her story is resolved in the context of the mushi's influence, with Ginko uncovering the connection between her arrival and Akane's fate.
