Zekkyou Gakkyuu: Tensei

Three episodes aired on TV as part of the Ribbon x Oha Suta specials.

Haruka Ozawa's sophomore year is getting seriously scary. One of her friends is possessed, another has committed suicide and Haruka could be the next one to flunk the still-breathing test. Her only way out of this potentially lethal dead end? Yakumo Saito, an enigmatic student born with a mysterious red eye that allows him to see and communicate with the dead. But the deceased don't always desist and some killers are more than ready to kill again to keep dead men from telling any more tales. That doesn't stop Haruka's knack for digging up buried secrets, and there's even more evidence of bodies being exhumed by both Yakumo's police contact and an investigative journalist with a newly made corpse in her closet! Can this pair of anything but normal paranormal detectives solve the ultimate dead case files or will they end up in cold storage themselves?

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.

Yuuko's antics are causing more ghost stories to circulate around the school, and Kirie, at her wit's end, attempts to rein Yuuko in with a series of games. Later, the Paranormal Investigation's Club investigates a series of stories which, one by one, lead to a series of interesting situations.
