The modern man Mikage accidentally traveled to the world of Naruto and became the descendant of an almost extinct ancient family "Mikage". The blood inheritance limit of this family is not a powerful offensive ability, but the ability to sense and even weakly affect the flow of chakra and life force in others.
She grew up in a ninja school with Naruto and others, relying on her vague memories of the future and her own unique abilities to carefully survive in this crisis-ridden world. She cannot change the situation of the battle positively like a real strong person, but in her own unique way, she can become the most indispensable "tuner" in the center of the whirlpool.
When everyone only saw Naruto as a "demon fox", only she could "see" the loneliness and struggle under the violent chakra. She didn't want to be a hero, and initially just wanted to live, but when the bond deepened, she decided to use her eyes that could see through the "reality" to protect the boy who was misunderstood by the whole world.
