1000 years ago, the Demon King caused a great amount of trouble for the human realm, but was sealed by the legendary hero. Now in the present, a large hole has appeared in the world, from which a large number of demons have emerged. The King has ordered the 75 probable descendants of the original hero to destroy the demons and save the world. Senyu follows the story of Alba, hero 45, and his quest to save the world. Along the way he is accompanied by Royal Soldier Ros, who is less than helpful. The plot contains a number of twists and turns, fitting the screwball nature of the manga/anime, including Alba teaming up with the Demon King herself, a pink haired young girl, and demons like Janua Ein to defeat the renegade demons responsible for the holes in the world[3]
