Loudmouthed martial artist Junpei Ryuzouji, elegant actress Airi Komiyama, and cheery but artillery-obsessed student Ritsuko Inoue all find themselves transported from their homeland of Japan to an unfamiliar, magical world. When the elven priestess Celcia Marieclaire casts the spell to send them home, she is interrupted, and the spell is broken into parts that scatter throughout the world. The spell fragments imprint themselves onto the skin of various elves. The trio travels in Ritsuko's tank, searching for elves who might carry the spell fragments so that Celcia can transfer them to her own body and make the spell whole again. As they adventure, people begin to refer to them as "Those Who Hunt Elves," gaining a reputation as warriors that put a stop to evil-doers with their miraculous cannon, terrifying elves by stripping any that they find. Though they're not the smartest group, they make up for it with enthusiasm and their strong determination to get back to Japan. [Written by MAL Rewrite]

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.
