"Sorcerous Stabber Orphen" is a fantasy anime series based on the light novel series by Yoshinobu Akita. The story is set in a world where magic is a central element of society, and it revolves around the protagonist, Orphen, a powerful sorcerer with a tragic past. Orphen, whose real name is Krylancelo Finrandi, was once a student at the prestigious Tower of Fangs, a magical academy. His life takes a dark turn when his adoptive sister, Azalie, undergoes a catastrophic transformation into a monstrous creature known as the Bloody August due to a failed magical experiment. The Tower of Fangs covers up the incident, declaring Azalie dead, and Krylancelo is expelled after attempting to uncover the truth.

Years later, Krylancelo adopts the name Orphen and becomes a wandering sorcerer, dedicating his life to finding a way to reverse Azalie's transformation. His journey is fraught with danger as he encounters various factions, including the Tower of Fangs, which seeks to eliminate him to keep their secrets hidden. Orphen is accompanied by a young girl named Cleao, who becomes his apprentice, and her bodyguard, Majic, who provides both comic relief and support. Together, they navigate a world filled with political intrigue, powerful magical entities, and moral dilemmas.

The narrative explores themes of redemption, loyalty, and the consequences of wielding immense power.

As the story progresses, Orphen uncovers deeper truths about the Tower of Fangs, the nature of magic, and the forces that seek to manipulate both for their own gain.
