PLOT
Life is depressing and normal for high-schooler Kensuke Nimura - except that he can see spirits. This ability generally hinders him more than it helps him, until he encounters Kagura Tsuchimiya while being pursued by evil spirits. They accidentally kiss and fight off the spirits together. A few days later, she transfers into his class. Kagura is an agent of a government agency that defends the public against supernatural enemies. She wields Ga-rei, a spirit beast that kills these spirits. Kensuke's spiritual awareness and his attraction to Kagura forces him to follow her to the agency, where he is recruited to fight the supernatural.Their first enemy is Yomi Isayama, an old friend of Kagura's, now an evil spirit due to a stone known as the sesshōseki. Also introduced is another old friend, the perverted Izuna Noriyuki. Yomi tries to release an ancient immortal demon sealed under Tokyo. The Agency manage to stop her after a long battle, resealing the demon and killing Yomi in the process. A mysterious boy removes her sesshōseki, and disappears.The next story arc concerns the re-emergence of a sect known as the Juugondō and its heir, Shizuru Imawano.
