|Season 1, Episode 2|
Zwei wakes up after the girl's attack. The girl comes into his room telling Zwei that she will not attack him anymore. She introduces herself as Ein. Ein conducts personal training to Zwei after agreeing to work with Inferno for several days, ranging from sparring in martial arts to small arms use in order to hone his skills as a potential Inferno assassin in upcoming Inferno-approved missions. Claudia enters the complex right after Scythe Master picks up Ein without revealing her presence and tells Zwei about the objectives of Inferno, as well as to give "hope" to Zwei that he can find out who he is before she leaves him with a goodbye. Meanwhile, the Scythe Master deploys Ein in an assassination mission somewhere in the United States to kill a person of interest.
