07-Ghost

When demons walk the streets, the cops need to recruit more demons! In a town where humans and demons co-exist, it takes more than a normal police force to maintain the peace. Enter the Hiizumi Life Counseling Office, a fantastic foursome of unique teenagers, each gifted with an amazing super power! Since it sometimes takes real demon-fire to fight demon fire, the first three quarters of the team aren't exactly human: Ao, a cat-eared telepath; Kotoha, a half-human conjuror; and Hime, descended from a dragon (and the town's acting mayor), all of whom also happen to be delightfully female. Rounding out the group is the token male and human, Akina, the office director and "Oyakume," capable of banishing spirits permanently (and from their point of view quite fatally) via a process called tuning. They may not look as impressive as some other superhero teams, and they certainly don't have the most dynamic name ever, but come hell hounds or high water, but they will defend their city!

Something evil is stirring in the shadows of Tokyo... During the spring of his senior year in high school, quiet Tatsuma Hiyuu transfers to Magami Academy in Shinjuku. The mysterious boy's "outsider" status and his profound skills in martial arts quickly earn him the friendship of class delinquent Kyouichi Houraiji. Through an uncanny connection and a happenstance challenge, he also meets Yuuya Daigo of the wrestling club, the captain of the girls' archery club, Komaki Sakurai, and Aoi Misato, the Student Council President. During their encounter, there is a sudden, harsh disruption of the Ryumyaku (literally Dragon Pulse, otherwise known as Dragon Vein or Dragon Stream), the flow of arcane energy. The surge awakens within the five teenagers a latent power, giving them each a supernatural ability. Enlightened to their newly acquired gifts by Hisui, the young heir of the Kisaragi Clan who maintains his family's antiques shop - as well as their duty to protect Tokyo from Oni (demons) - the Magami students decide to use their power to protect the city from the onslaught of dark forces. Battling the demons alongside Hisui Kisaragi, the five unlikely friends discover that they may have to face a greater threat to Tokyo other than destroying a few malevolent, random monsters. The Ryumyaku had been disrupted by force, from someone invoking the Dark Arts - and that person has a wicked desire to unleash a long-dead evil. Can the teenagers overcome their own fears and flaws to fight against the Dark Arts? And soon they will also have to face their own destinies as they discover their Stars of Fate. This anime is based on a manga, which was based on the Nintendo role-playing video game originally released in 1998.

While at school, Taniyama Mai and her friends like to exchange ghost stories. Apparently, there is an abandoned school building on their campus that is the center of many ghost stories. During the story, they are interrupted by a mysterious male figure. The person turns out to be Shibuya Kazuya, a 17 year old who is president of the Shibuya Psychic Research Company. He was called by the principal to investigate the stories surrounding the abandoned school building. The next day, on the way to school, Mai passes the school building in question. While examining a strange camera she spotted inside, she gets surprised by Kazuya's assistant. Unknowingly interfering with the investigation, Mai breaks the camera and Kazuya's assistant gets injured. Kazuya forcefully hires Mai in order to pay for the camera and replace his injured assistant. From that point on, Mai begins to learn about the paranormal world and the profession of ghost hunting.

In the year 2012, the world is a wasteland invaded by aliens. Time travelers like Fumiaki are sent back to the year 1999 in order to destroy the "Nostradamus Key" to prevent the apocalypse. In 1999, Maya, the daughter of the former principal of Waldstein Academy (a.k.a. Occult Academy), returns to the academy to replace her father. Despising her father's obsession with the occult, Maya is hell-bent on running the school into the ground out of spite. Her plan is interrupted when she meets Fumiaki and learns of the forthcoming destruction of the world. They form a pact to look for the key.
