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.

The 12th Zodiac Tournament begins in a desolate city, devoid of any evidence of the half million people who recently lived there. To raise the stakes, each warrior ingests a poisonous gem, thus setting a time limit on the tournament—and on their life. With one wish for the victor up for grabs, the Zodiac Warriors start their cutthroat battle for survival. [Written by MAL Rewrite]

College student Yuuhi Amamiya's monotonous life is turned upside down with the appearance of Sir Noi Crezant, a talking lizard claiming to be a knight of justice. Crezant elaborates that the world is in peril—threatened by the mage Animus who wishes to annihilate it with his Biscuit Hammer, an enormous structure suspended in Earth's orbit. As the newly appointed Lizard Knight, Yuuhi must fight alongside other Beast Knights to protect the princess and save the planet from destruction. Unimpressed by the prospect of risking his life, Yuuhi continues his day as usual—until a golem created by Animus suddenly confronts him. Yuuhi is instantly overpowered, but his neighbor, Princess Samidare Asahina, luckily rescues him. To his surprise, Samidare's intention starkly differs from Crezant's; instead of saving the world, she aims to destroy it with her own hands. Captivated by her firm ambition, Yuuhi resolves to become stronger and help Samidare realize her goal. As the pair continues to fight against Animus' golems, Yuuhi finds himself gradually gaining an interest in life—but the chains of his past trauma may restrain him from progressing further.
