Orphaned early, Krylancelo Finrandi grew up in an institution alongside Azalie Cait-Sith and her cousin Leticia. His adoption into the Tower of Fangs led him to train under Childman Powderfield, where his prodigious talent placed him among thirteen candidates for Court Sorcerer. His life fractured when an experiment with Childman and Azalie on the Sword of Baltanders transformed Azalie into the monstrous Bloody August. Prioritizing reputation over rescue, the Tower exiled Azalie, declared her dead, and buried the truth. Shattered by this betrayal, Krylancelo discarded his name and position, rebranding himself "Orphen" to sever ties with the Tower. He dedicated the next five years to a singular quest: reversing Azalie's curse.

Orphen presents a carefree, often lazy facade, masking intense focus and resilience. His exterior is rough, sarcastic, and fiercely independent; he vocally complains about others' troubles yet consistently intervenes to aid them, driven by a deep-seated sense of justice. Loyalty to Azalie borders on obsession, fueling his journey. Despite cynicism, he forges strong bonds. He takes Majic Lin as his apprentice, offering gruff but genuine mentorship. This "jerk with a heart of gold" complexity sees him wield sarcasm as a shield while undertaking perilous missions for others, confronting entities like the Tower of Fangs or celestial beings.

Core relationships anchor his path. Azalie remains his central motivation; his devotion to saving her endures even after learning she willingly participated in dangerous experiments and later inhabited Childman's body through white magic. He acts as a reluctant guardian and mentor to Cleao Everlasting, encountered during a scheme involving her family's sword, and Majic Lin, whom he taught sorcery while lodging at his father's inn. This dynamic evolves into a found family, with Orphen displaying fierce protective instincts when they face threats like the Dragon Faith or celestial conflicts. Tension, betrayal, and unresolved history mark his interactions with former Tower allies like Hartia and Childman, especially after discovering Childman allowed Azalie to possess his body, leading to tragedy.

Orphen stands as a high-level sorcerer renowned for exceptional versatility and reaction speed. He counters spells from multiple Tower sorcerers simultaneously and momentarily holds his own against dragon-level threats like Bloody August or Deep Dragon. His combat style merges physical prowess with magical skill, earning him the moniker "Sorcerer Stabber" for using knives and hand-to-hand techniques alongside sorcery. He excels as a Kung-Fu Wizard, dispatching foes with precise strikes even without magic, and employs tactical spellcasting—binding spells or environmental manipulation—tailored to diverse situations. This adaptability extends to problem-solving, blending brute force with clever strategy.

His journey spans numerous arcs. It begins with his pursuit of Azalie and the Sword of Baltanders, leading him to Totokanta and partnerships with Cleao and Majic. Key events include clashes with the Tower's forces, encounters with Deep Dragon and its offspring Leki (who joins as a companion), and unraveling conspiracies involving Azalie's possession of Childman's body. In the Chaos in Urbanrama arc, his quest expands into a broader conflict between celestial beings and humans, forcing him to navigate large-scale warfare while confronting revelations about Azalie's choices and the world's deeper magical secrets. Through these trials, his resolve is tested, but his core drive—to save Azalie and protect his companions—remains steadfast, defining him beyond his origins as a disgraced sorcerer.
