Leiot Steinberg operates as a rogue tactical sorcerist in an alternate 1899, where state-regulated sorcery carries the peril of demonic metamorphosis. Clad in a volatile Mold suit to stave off corruption, he wields ruinous magic against supernatural threats, his missions marked by chaotic destruction that strains relations with authorities. Government enforcer Isaac Hammond, bound to Leiot by a fractured history of shared tragedy and mutual loss, relentlessly pursues him, their clashes fueled by unresolved vendettas and ideological divides.

Forced as a youth to execute his demon-twisted mentor—the man who once rescued him—Leiot’s life became a series of grim reckonings with sorcery’s toll. This pattern deepened when his role in his former partner’s familial tragedy surfaced, etching guilt into his every action. Now, he seeks absolution through relentless combat, even as his alliance with Kapelteta, a youth tethered to his past, tempers his self-destructive impulses.

Kapelteta’s influence anchors his fraying morality, countering his spiraling feud with Isaac, which ignites over a conspiracy involving sabotaged Mold suits and the haunting specter of Isaac’s slain sister. Their final confrontation culminates in tragedy: Leiot delivering a mercy stroke to a demon-transformed Isaac, mirroring his mentor’s fate and entrenching the cycle of violence he despises.

Driven by penitence and a death wish, Leiot gambles with the forbidden Accelerator—a technique amplifying his lethality while hastening his own demonic unraveling. His journey teeters between annihilation and redemption, a relentless negotiation of sacrifice and survival in a world where every spell cast exacts a price in blood and conscience.
