Sorcerous Stabber Orphen (魔術士オーフェン, Majutsushi Ōfen, lit. "Sorceror Orphen") is a series of Japanese fantasy adventure novels and manga, two anime television series (Sorcerous Stabber Orphen: Begins and Sorcerous Stabber Orphen: Revenge), and a video game.

Krylancelo Finrandi once attended the most prestigious school of sorcery on Kiesalhima continent, the Tower of Fang. He was sent there as a young child from an orphanage, along with another orphan girl called Azalie. Throughout the years, the two were very close, with Azalie becoming more and more powerful and Krylancelo looking up to her as a sister/mother figure and a best friend. It isn't until one day, Azalie's thirst for knowledge and extracurricular experimentation backfire, and she is horribly transfigured into a hideous creature, a dragon-like beast that departs the Tower in an animal fury, leaving Krylancelo behind. The Fang Tower, however, is unsympathetic. They promote the belief that Azalie is dead in order to cover the grievous error that resulted in her unimaginable transformation, a terrible scandal that would surely destroy the school's reputation and authority. People whom Krylancelo thought were his friends suddenly seem as though they are strangers, even enemies, going along with the Tower's pretense rather than challenge their authority. Furious that they will do nothing to help her and are instead determined track down the Bloody August and destroy it before the truth can come to light, Krylancelo renounces his former self, declaring Krylancelo to be dead and that he is, instead, Orphen.

After five years, he finds himself living in the quiet town of Totokanta and taking on a student - Majic Lin, his landlord's son. Life is quiet and fairly lazy until the day Cleao Everlasting comes home from boarding school, and stumbles into Orphen's quietly laid plans for the sword that sits on her family's mantle: the Sword Of Baltanders. It turns out that the sword is actually one of three magical artifacts that Orphen will need if he is to save Azalie, and, in fact, was the very sword Azalie used in her experiment that ended with her unfortunate transformation. Before he can obtain it, however, the Bloody August assaults the town looking for the sword, and soon after, Tower's forces show up as well.

To find the other Baltander's relics, Orphen sets off with his apprentice, little miss Everlasting and two short-statured misfits, but at all times they need to stay ahead of the Tower of Fang and its sorcerers, who all believe that bringing Azalie back to her former state would reveal their oversight in containing her increasingly dangerous magic, a mistake so great it could bring the Tower down - and, of course, ahead of Azalie herself who, as the dragon is more powerful than both Orphen and the Tower. Orphen is driven solely by the need to transform Azalie back into her human self at even the cost of his life. But restoring Azalie ends up being only the beginning...
