Phantom -PHANTOM THE ANIMATION-

A witness to one of Inferno's assassinations, marked for death, instead gets captured by the killer responsible, a young woman named Ein, and brainwashed into her trainee under the new name Zwei. Guided uneasily by handlers Claudia McCunnen and Lizzie Garland, Zwei trains alongside Ein while looking for any way out of the organization that erased his past. This three-episode OVA adapts only the opening chapter of the Phantom of Inferno visual novel, condensing and altering much of that material.
