Sorcerous Stabber Orphen(魔術士オーフェンはぐれ旅)

Orphen is a powerful sorcerer who is notoriously lazy. Everything changes when he finds a way to save his sis, who was turned into a dragon during their days at magic academy. Betrayed by friends who refused to help, Orphen will stop at nothing to track her down, even if he has to go it alone.
