Desir Herrman hails from a timeline where humanity nearly perished due to the Shadow World and its Shadow Labyrinth. As one of just six survivors reaching the labyrinth's final level, he helped defeat the boss Boromir Napolitan. The dragon's heart exploded upon death, unleashing catastrophic mana that destroyed the world and killed the last survivors. This event triggered Desir's return 13 years into the past, coinciding with his enrollment at Hebrion Academy. Armed with future memories, he resolved to prevent the coming catastrophe and save those he lost, particularly comrades Romantica Eru and Pram Schneider. Physically, Desir is a tall teenager with fair skin and unbrushed black hair. His face is long, tapering sharply toward his chin. After losing vision in his left eye from wielding forbidden magic against the Demon of Doom Dadaneuph, he styles his hair to cover the damaged eye. This injury occurred despite no physical trauma to the eye itself, serving as a permanent repercussion for channeling excessive mana through Dragon Tongue magic during that conflict. Desir's personality is heavily influenced by the trauma of witnessing mass death and personal loss in the Shadow Labyrinth. He exhibits PTSD symptoms, particularly linked to Romantica's death and other comrades in his original timeline. This fuels his unwavering determination to prepare the world for the Shadow World's return, accepting morally ambiguous actions or personal sacrifice. He undergoes an artificial Magic Circle implantation with low survival odds and willingly endures cycles of physical destruction and healing in high-stakes battles. His training of allies is rigorous and uncompromising, driven by knowledge of their future capabilities and the need for their survival. Initially, Desir possessed mana levels qualifying him only as a First Circle mage. After soul-binding with the Crest of Toa from a Shadow World, his mana capacity increased to Third Circle level. His combat effectiveness stems from specialized skills and strategic intellect, not raw power. Analysis Magic forms his core fighting style, enabling him to deconstruct and neutralize opponents' spells with computational speed surpassing even Zod Exarion, the sole Seventh Circle mage. This proficiency earned him the moniker "Anti-Mage" among Shadow Labyrinth survivors. Beyond spell analysis, Desir mastered Close Quarters Combat under Donovan Asylan's tutelage during the Shadow Labyrinth campaign. He also mastered Magic Gem Enchanting, allowing direct mana extraction from gems to cast spells beyond his Circle rank. Acquiring Dragon Tongue magic permitted casting spells affecting mana itself, initially at great physical cost. Later innovations included a Hybrid Magic System combining Dragon Tongue with conventional magic, creating potent effects without permanent physical repercussions, though it remained mana-intensive. Key power advancements came through a self-implanted artificial Magic Circle, elevating him to Fourth Circle, with Dragon Tongue amplification reaching Seventh Circle levels. This enabled victories against formidable opponents like Aaron, a King-Class Knight enhanced by homunculus fusion. Later, Desir absorbed a Dragon Heart's energy, granting near-infinite mana reserves. Desir founded and led the Starling Party at Hebrion Academy, with core members Romantica, Pram, and later Azest Kingscrown. He strategically leveraged institutional positions, accepting roles as Technical Adviser and later Tower Master of the Tower of Magic following Zod Exarion's death, gaining access to advanced equipment like the Aurora System. He also joined the Royal Guard under Emperor Gilltian Jedgar F. Roguepalace, securing powerful artifacts for his party. Significant events demonstrating his development include outperforming nobles like Azest in Hebrion's entrance exam despite discriminatory class placement systems relegating commoners like him to the under-resourced Beta Class regardless of merit. During the Attack on Deltaheim, he led the recapture of a teleportation gate to block enemy reinforcements. His confrontation with Crow Mask and Dadaneuph culminated in the sacrificial Dragon Tongue casting that cost his left eye's vision but earned him the "War Hero" title. Later, he guided combined parties (Starling, Blue Moon, Red Dragon) to safety during a compromised dungeon expedition.
