Want to Become the Second Personality of the Boss Behind the Scenes

In the era of peace, there were demons and ghosts causing harm to the world. Fortunately, there were psychics who could control spirits and exorcise demons to protect the world. My name is Yi Nagi, and I am an ordinary high school student who accidentally traveled to this different world full of aura. The bad news is that it did not completely occupy the body of the host named Yi Feng, but became his second personality. The good news is that you have mastered the powerful strength that the first personality cannot exert. This kind of powerful strength can certainly allow me to stand out as a psychic in this world, but I don't care about love and justice. I am just a simple fun-loving person. For this reason, I have formed an organization that walks in both good and evil. Aim to become the mastermind behind the scenes that interferes with all forces and secretly controls the situation!
