KAMUI ---He's behind you

うしろの正面カムイさん

Shizuka is a normal high school girl with the ability to see ghosts. Due to her peculiar tendency to attract ghosts, she works as an assistant to Kamui, a famous psychic. Kamui takes pride in his top-notch psychic abilities, but the way he exorcises ghosts is rather unusual! (Source: Shogakukan, translated)
