Doomed Megalopolis

Ten Years ago, Genichirou Izayoi died trying to stop the sorcerer Rebi Ra, and as a result Shinjuku became a playground for demons. And now, the day approaches when Rebi Ra will complete his decade-long ritual to plunge the rest of the world into chaos! As Genichirou's son, it falls to Kyouya to venture into the heart of Shinjuku and put an end to the sorcerer his father couldn't beat. Can Kyouya exceed his father's legacy, or will the demons of Shinjuku create Hell on Earth?

A satanic program is activated aboard a crowded commercial flight headed for Tokyo. It releases a swarm of invisible demons that send the aircraft plunging to a fiery doom. Everyone aboard is killed instantly - except Akito Kobayashi - owner of the devilish program and sworn ally of hell itself. Kojiro Soma, an old elementary school friend of Akito`s, is surprised to see him enroll back in school. Kojiro notices how this once lonely boy has grown into a suave and arrogant teenager. Later, when his classmates are attacked and legendary demons return to stalk to streets of Tokyo, Kojiro begins to truly understand what his old friend has become. Akito has plans for the human race. The plans revolve around magnetite, the mysterious element that forms the living essence of every human soul. Combined with his demonic software, a strong enough source of magnetite would release a plague of devils upon the Earth. That source exists in Kojiro`s class, but when the evil plan expands beyond even Akito`s grasp, it is Kojiro who must find the ultimate power within himself, and go head-to-head with the greatest demon of all!

From the beginning of time, Earth has been enslaved by the powerful and grotesque Ogres. The dominance these arrogant immortals hold over the helpless victims is challenged only by the noble Guardians. Eons later, in the year 2089, few Ogres of Guardians remain in Neo-Shinjuku. Humans rule the Earth; yet, deep within the dark underworld of the city, the supreme Ogre is still alive and is preparing, once again, to enslave the Human race.

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.
