Tougo Narutaki has a brief moment in the early episodes of the first season. He is shown as Tatsuma Hiyuu&#039;s martial arts master, and also the person who enrolled Tatsuma in Magami Academy, telling the boy his talents would be needed. Afterwards, he seems to disappear.    Tougo emerges in the anime&#039;s second season as the Chief of the assassin organization, Martial Fist. He has also taught Kureha Mibu his martial arts. Dark and professional, Tougo surprisingly is an antagonist and supposedly the one who orders the hit on the Magami Five. However, the dismal character is renounced as a familiar-spirit sent by Munetaka Yagyuu to use the Martial Fist, and the real Tougo returns to once more take command of the organization and help the new Stars of Fate.     The character is debuted in the videogame &quot;Tokyo Majin Gakuen Oboro-Kitan&quot; as a close friend of Genma Hiyuu (Tatsuma&#039;s biological father) which is also shown throughout the anime in flashbacks. Together Genma and Tougo created their martial arts form Yin no Toshukuuken.

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 second season of Tokyo Majin Gakuen Kenpucho.
 
The battle against Tendou Kodzunu is over, and the Magami Five begin to look forward to their senior graduation, hopefully planning for their adult futures. However, life in Tokyo is not at peace... 
The underground assassin group known as the Twelve Heavenly Generals of the Martial Fist begin to move against those protecting the city from demons. Normally rumored to kill criminals that the mundane law was unable to bring to justice, the Martial Fist now set their sights on Tatsuma Hiyuu, Kyouichi Houraiji, Aoi Misato, Komaki Sakurai, Yuuya Daigo, and Hisui Kisaragi. 
What is the purpose of this cruel turn of events? And who ordered the hit? New threats emerge as others awakened to powers unleashed by the Ryumyaku seek out the Magami kids - and old friends now return as enemies. 
Destinies will collide as the Stars of Fate begin to merge; Yin and Yang will meet. And soon the shadowy figure pulling the strings will reveal himself, in an effort to raze Tokyo to the ground and awaken the Vessel of the Golden Dragon.

 In the night of Tokyo, mysterious deaths involving the 'Reborn Dead' occur. Mysterious transfer student, Tatsuma Hiyuu, and delinquent student, Kyouichi Houraiji, fight these undead every night. They, along with the rest of their group, soon realize that a greater threat, that involves even more powerful demons, is near.
