TV Special
Description
Leonardo Bistario Harwey commands sixty percent of global wealth as heir to the Harwey dynasty. Born to the family’s former patriarch and his mother Alicia, he was marked as the dynasty’s future ruler from infancy. His half-brother Julius, judged unfit for succession, received orders to assassinate Alicia to clear Leo’s path. From age three, Leo endured surgical and thaumaturgic procedures implanting knowledge directly into his neural pathways, forging him into an impeccable leader. This conditioning left him emotionally detached, devoid of ordinary human sentiment until his inaugural brush with despair following defeat.

In the Moon Holy Grail War, Leo summons Saber Gawain as his Servant, flaunting his ally’s identity with unshakable certainty in his preordained triumph. He seeks the Holy Grail to avert perpetual global strife, convinced that its power in any single individual’s grasp would trigger chaos. He champions a totalitarian order where disparate individuals submit to equal coexistence under Harwey dominion, prioritizing species preservation over familial supremacy.

During *Fate/EXTRA CCC*’s Far Side incident, Leo retains Gawain despite memory erosion and mobilizes the student council to flee the corrupted Moon Cell stratum. Confronting BB’s menace, he expends every Command Spell to sever his pact with Gawain, guaranteeing the Servant’s survival while transferring authority to Hakuno Kishinami—a sacrificial pivot from his prior hubris.

Centuries post-defeat in *Fate/EXTRA Last Encore*, Twice H. Pieceman rescues Leo, who adopts Twice’s conviction that erasing human history will halt stagnation. Ascending as “King of the Land,” he governs a warped iteration of SE.RA.PH., mirroring his ideological pivot from imposed stability to advocating cyclical annihilation as regenerative catalyst.

Leo’s demeanor merges regal magnetism with clinical detachment. He compels obedience through an aura reminiscent of dawn’s reassurance, yet his exchanges remain devoid of authentic empathy, particularly toward artificial entities like Sakura Matou and Rani VIII. Despite his orchestrated poise, flashes of juvenile humor and inquisitiveness surface in non-combat contexts, hinting at suppressed vestiges of humanity.

His visage shifts across timelines: within the Moon Cell’s Near Side, he sports a vibrant orange academy uniform, while the Far Side sees him don a standard black uniform to assimilate. In *Last Encore*, his avatar manifests older, clothed in a beige trench coat emblematic of his transformed station.

Leo’s narrative examines the paradox of a sovereign engineered for flawlessness yet stripped of mortal fragility. His trajectory from certain conqueror to self-sacrificing agent and eventual ideological adversary highlights themes of dynastic legacy, doctrinal inflexibility, and the price of utopian ambition.
