Yuna is a 22 years old girl who works for the FBI investegating murder case victims. Since from a young age Yuna has had the ability to see ghosts, but at one twisted condition. The ghosts have been murdered when they were alive. As little, Yuna didn't understand, why would all these random people who were also dead come ask a little girl for help? what would she be able to do? but as she grew older she decided to use that power to help the ghosts find peace. .

Yuna became an FBI agent. Her role is to investegate murder cases with the help from the victims. She is a very serious person since she had to grow up fast with such scary abilities.
