Sayo Hirasaka is a second year student at Sakurazuka High, and member of the Gardening Club. In the anime, she is introduced in a round-about way. She is seen with her parents during the incident with Ryouichi Karasu—the demon crow destroys the highway the Hirasaka family is driving on, and smashes their car. It is assumed the innocent Sayo is killed in the crash, much to Tatsuma Hiyuu's grief.   ~!Sayo returns later on, surprising Tatsuma by running into him by coincidence. The two seem to start dating, which shocks his friends; Kyouichi is the only one to remember the girl, causing him to be suspicious. Because her parents were killed, Sayo claims she must leave Tokyo for the countryside, to live with her grandparents on a farm that cultivates sweetpea flowers. Tatsuma accompanies her on the train ride, and walks her to her grandparents.  However, he falls into a trap by Tendou Kodzunu. Sayo had indeed died with her parents, but was resurrected by Tendou's Dark Arts; the half-dead corpse of Sayo accepted his offer in exchange for also bringing back to life her parents. In the end though, she couldn't stand betraying Tatsuma and saves him—only to be stripped of the power keeping her alive.!~ Sayo's history is slightly different in the original video game, but she is still used the same. She is also a descendant of Hirasaka from the prequel game Tokyo Majin Gakuen: Gehouchou.

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.
