Description
Codenamed "Phantom" within the criminal organization Inferno, Ein—originally named Eren—is a highly skilled assassin shrouded in mystery. Brainwashing-induced memory loss obscures her past, though fragmented recollections hint at a childhood in a village destroyed by massacre. Sold to a brothel afterward, she was later claimed by Scythe Master, who forged her into his first experimental Phantom through three years of brutal training. The process erased her identity, molding her into an emotionally detached weapon conditioned for unhesitating obedience.

Her personality is marked by apathetic loyalty to Scythe Master, viewing herself as little more than a tool. Yet beneath her icy demeanor lies an unexpected reluctance to kill without orders or immediate threat—a flicker of suppressed humanity. This contradiction crystallizes in her bond with Zwei, a fellow assassin she trained. As admiration for him deepens into affection, her programmed obedience wavers, sparking pivotal choices: sacrificing herself to shield him from Scythe Master’s wrath or abandoning Inferno to adopt the alias "Elen," posing as Zwei’s twin sister in Japan.

Her narrative branches into diverging fates. One path sees her perish defending Scythe Master from Zwei’s lethal strike; another grants survival, fleeing with Zwei to seek peace while unraveling her murky origins—traces pointing to Mongolian heritage, though definitive answers elude them. A third thread weaves her demise through a poisoned flower petal, a symbolic end shared tragically with Zwei.

In combat, she employs surgical precision, specializing in close-quarters strikes to vital points. Preferring defensive analysis before lethal counters, she relies on strategic experience over innovation—a contrast to successors like Zwei. This expertise lets her outmaneuver rivals such as Drei, whose connection to Zwei marks them as threats.

The OVA hints at deeper trauma through an unnamed older brother and reinforces her village’s destruction as the catalyst for her fractured existence. Across all iterations, her struggle centers on seizing autonomy from manipulation, with Zwei’s influence sparking fleeting acts of self-determination.
