Shima no Nushi

An old woman with three white eyes and a flashy red kimono. Long ago known as "Jun Aikawa", now only a woman bearing no such name, nor the title of Humanity's Strongest or a contractor. Now ruling a lone, deserted island with many odd, mysterious properties. The Lord of the Island hates when she is referred to as a "grandma", though such only happens with other elders. Even though she is much older than Jun, she has strength that far surpasses the current Jun's strength. She is allegedly able to stop the rotation of the stars by sheer force, even with the title of "Humanity's Strongest" being passed on to someone else.
