Senyu
Plot. 1000 years ago, the Demon King caused a great amount of trouble for the human realm, but was sealed by the legendary hero Creasion. 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 number 45, and his quest to save the world. Along the way he is accompanied by Royal Soldier Ross, who is less than helpful and whose  semi antagonist antics provide humor. The plot contains a number of twists and turns, fitting the screwball nature of the manga/anime. Alba quickly teams up with the demon queen herself, a little pink haired girl who reveals the whole issue was an accident. The series starts almost exclusively comedic, with episodic gags mainly involving Alba's bad luck and Ross abusing him. A more serialized story and plot starts to develop halfway into Volume 1, as an order of 12 powerful demons themed after the 12 months of the Gregorian Calendar starts making its move to revive the original  Demon King. Simultaneously, other of the probable hero descendants also interfere, with lesser demons and government officials caught in the crossfire. The past and origin of the world's affairs are explored in the second volume, as well as Creasion's role in history and his modern whereabouts. The third volume focuses on the remnants of the 12 demons, especially the strange machinations of one of them, Elf November. The fourth volume explores Elf's past and his complex involvement with existence as well as the true nature of several elements of the world. This volume concludes Senyu's main  original storyline. Volume 5 serves as an epilogue, tying up loose ends from the rest of the story and later shifting to a comedic slice of life where the characters are adapting to the world after all the changes brought in by the catastrophic events told in the past volumes. The later portion of Volume 5 starts a new serialized storyline, reexploring some aspects of Elf's past and bringing a new group of antagonists Characters.
