Windows to the Soul

Nana Nozomi, aka Teller, is the nickname of a class three Jujutsu Sorcerer. She wields the Cursed Vision technique, an ability that allows her to see into the minds of others and, in special cases, their pasts, depending on their cursed energy levels.
One day, she runs into the special grade curse, Mahito. Without realizing exactly who and what he is, Mahito finds interest in her abilities.
He sees it as something that intertwines with his own beliefs, a way to see a persons soul, and he wants to know more.
