Mikage is a young woman who appears in the anime Refrain Blue. She is encountered by the main character by chance during a visit to the Dragonfly Coast, a remote seaside area. Seven years prior to the story, she sustained a leg injury that prevented her from continuing to run marathons, an activity that had evidently been important to her. As a result, she arrived at the coast in a state of personal despair, seeking solace. She has a habit of finding spots with a good view of the ocean from the top of a mountain and spending her time drawing pictures. Her artistic inclination and her presence at that secluded beach suggest a reflective, somewhat melancholic personality. Her past injury and the loss of her ability to run form a key part of her background, shaping her motivations. In the story, she serves as a kindred spirit to the main character, who is also grieving a loss. Their relationship develops over the course of the summer, marked by mutual understanding and a brief romantic connection. Little else is directly documented about her family, other relationships, or any special abilities beyond her drawing and her quiet resilience. Her development centers on confronting her past pain and the temporary nature of the summer encounter.
