Mixed Worlds: The Mage with the Sharingan

Having died young in two previous lives, she wishes to live a full life in her third. Unfortunately, this is a high-risk ninja world, her current body belongs to the Uchiha clan, and her boyfriend is one of the perpetrators of the clan extermination.

She can't escape? How can she survive?

She struggles with all her might to stay alive. During an experiment involving jumping through space-time, she meets a green-haired kid who likes to hold a knife in his mouth. Over there, they have Devil Fruits. If she could eat a Logia-type, she would be immune to physical damage.

Intending only to visit the green-haired kid (and find a Devil Fruit), she unexpectedly arrives in another high-risk world where demons eat people at night. To make matters worse, she has exceptionally bad luck and encounters a demon with six eyes.

What now?

She's a mage. Isn't a close-range fighter at mid-range her natural counter?
