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.

Ein is dispatched to take out Inferno henchmen in a warehouse district as part of a plan hatched by Raymond and Claudia to eliminate Scythe Master. Claudia, in summoning Zwei to her mansion, gives him his Japanese passport and reveals his real name to be Reiji Azuma. When Zwei is in shock, Claudia offers him a place alongside her after revealing her feelings. However, Reiji returns back to the complex hideout to see Ein wounded after being shot by Lizzie when the two confronted each other. Reiji receives a call from Claudia, telling him that he would be killed if he would assist Ein in any way. Refusing to be intimidated, Reiji helps Ein remove the bullet from her wound before he secretly evacuates her from the complex in order to avoid being tracked down by Inferno for refusing to join with Claudia in her plans to take over Inferno and get rid of Scythe Master.

Godoh is furious over the murder of his men once again and demands an explanation with Claudia promising that she'll do everything in her power to smoke out the culprits responsible. Reiji was given the assignment to locate the culprits responsible for killing Godoh's subordinates. Accepting the assignment, Reiji brings Cal along to assess the situation and determine the potential sniping locations where the assassins will use to disrupt the meeting between Godoh and the executives of Inferno. During the meeting, Reiji was able to gun down one of the armed assassins during his counter-sniping assignment with Cal when he finds out that the sniper he killed is Randy Weber, the right-hand man of Wisemel. However, a second sniper rifle is heard when the meeting is interrupted. Godoh and his remaining subordinates point their sidearms at the Inferno executives. Reiji doesn't know that Ein had survived, being the second sniper for interrupting the Inferno-Godoh conference.

After exchanging formalities, Elen and Cal draw their weapons, leading to an even match between the two. Reiji arrives and tries to persuade Cal to end the standoff, but she refuses. The standoff ends when Lizzie interrupts and manages to convince Cal to leave. Lizzie lets Reiji and Elen go, but she warns them that Inferno won't let the pair off that easily. Reiji calls Shiga and threatens him using Mio to advise Inferno not to try anything. During her conversation with Lizzie, Cal reveals her dark thoughts and reasons for being an assassin. The next day, while Elen goes to negotiate their escape plans, Reiji and Mio go on a date again. While Mio is away, Cal appears to Reiji. He tells Cal that she can kill him on condition that she let Elen go. Cal states that she will make Reiji suffer before killing him. Later, Cal takes her frustration out on a group of thugs who get in her way.
