Years ago, Kirsi’s mother had gotten a phone call in the middle of the night informing her that her husband had died in a plane crash. Now in the present, Kastinen questions why Yin refuses to return to her home country, but she tells him that she doesn’t know. He responds by noting that she’s different from how she used to be and suggests that her heart is sick. Since Yin continues to say that she won’t go back, Kastinen places his finger on her lips and tells her of how he’s been searching for her wherever his performances took him. She asks him why, and before he can answer, the two are interrupted by Gai and Kiko asking to borrow some money. Meanwhile, Berta and Itzhak are headed in the same direction by car when they come across a police checkpoint with a man specifically looking for Contractors. Earlier, Berta had explained to Itzhak that her power allows her to break objects through vibrations, and she now uses it to stop the inspector’s heartbeat. While the other policemen are occupied with their fallen comrade, the two Contractors slip past the checkpoint. Itzhak stops the car further up the road so that Berta can take care of her price, and she reveals that she has to put foreign substances into her mouth which she then spits out.
When the train Yin and Kastinen are on stops briefly in the middle of the mountains, Yin notices a blue surveillance spectre in a nearby puddle. She tells Kastinen that someone’s chasing after them, so the two get off the train and run into the nearby forest. Neither Gai nor Kiko saw the two leave since he had been in the bathroom and she had been sleeping, though Gai decides to get off at the next station. Kastinen and Yin trudge through the rain until they arrive at an abandoned school house where they take shelter. When they find a piano inside, Yin starts playing it at the urging of her former teacher. Around this time, Berta is explaining to Itzhak how she had a baby daughter and had been a heavy smoker as a singer. Though she had quit during the pregnancy, she didn’t stay that way, and one day she inadvertently put a cigarette in her baby’s mouth, which caused her daughter to choke. Berta recounts that she had many swollen-eyed nights from crying, and before she knew it, the night sky changed. Hei is meanwhile on a different train and thinking about how Yin helped him that time inside the Heaven’s Gate with the meteor fragment.
Still playing the piano, Yin remembers how her mother had fainted during her father’s funeral and how her mother had gotten close to Kastinen afterwards. She had caught them staring at each other under the moonlight and had dashed out of the house nearly in tears. Kirsi had run onto road and would have gotten hit by a truck if not for her mother pushing her out of the way to safety. The cost of this, however, was her mother’s own life. As she recalls crying in front of her mother’s covered body, Yin now suddenly stops playing the piano and utters “Mama.” Kastinen realizes that she remembers what happened on that night and thinks that she doesn’t want to return home because sad memories remain. Yin tells him that if she hadn’t run out at the time, then her mother wouldn’t have died, and she feels that the silver light disappeared ever since then. With Yin acting like she is, Kastinen tries to explain that there was nothing going on between himself and her mother. Still, he admits that at the time he had hidden feelings of wanting to take her mother from her. Kastinen has wanted to tell her that she needn’t feel guilty for what happened.
Back in the car, Berta recalls a verse from an aria where atonement is symbolized by the eclipse of the moon. Hearing this, Itzhak wonders if the way the moon has been lost now means that they’re in a period of eternal atonement. Also headed in Yin’s direction is Hei who runs into Gai on the mountain path. Gai recognizes Hei from the construction site incident earlier and questions if he is the stalker after Yin, but Hei simply tells Gai to disappear since this doesn’t involve him. This gets Gai angry and he questions what Hei has done to Yin to make her silent and expressionless – like a doll. Ignoring this, Hei starts to walk off, so Gai stops him again and tries to make him understand that Yin is crying on the inside. Hei responds by shocking Gai unconscious and proceeding along the path towards the school building. Yin eventually senses that Hei has come, so Kastinen heads into the hallway to confront him. When Hei asks why Kastinen took Yin, the girl in question comes out to refute that. This causes Hei to realize that Yin ran away on her own accord, and Yin claims that it was because she felt inclined to do so.
Kastinen then accuses Hei of being Yin’s companion in doing suspicious work, and Hei admits that he is. This causes Yin to turn her head towards him, but shortly after, an ear-splitting noise starts shaking the building. Outside, Berta and Itzhak have arrived, and she’s using her powers to bring the building down. As Yin and Kastinen escape, Hei jumps out a window and rushes towards the woman, but Berta succeeds in stopping his heart with her power. In pain, Hei quickly administers an electric jolt to himself to start his heart up again, and before Berta realizes that he’s still alive, he shoots his cable around her neck and electrocutes her. Itzhak tries to make a run for the car, but he gets shot in the back by Huang with a sniper rifle. Huang then aims for Yin, however he notices first that the dying Itzhak has started to glow. Itzhak begins emanating outward all the surveillance spectres that he took in, and they soon cover the sky in a beautiful swirl. In his final words, Itzhak tells Berta that this is the light of the moon, a moon filling in silvery white. Both Hei and Huang are shocked to see Yin crying, and although Huang still takes aim, he can’t pull the trigger.
In the aftermath, another man approaches Huang in a bar concerning Yin and tells him not to worry because no real harm was done. He reveals that the defeated Contractors were connected to the FSB, and if information had been leaked, then Huang’s neck would be on the line. The man then tells Huang to hand over Yin for a reset, but Huang refuses because they’ve finally become familiar with how to use her. As Huang gets up to leave, the man warns him not to get lost in emotion. Yin has meanwhile returned to her normal tobacco shop spot, and as she sits there, she remembers what happened immediately after Itzhak and Berta died. Kastinen had tried to get her to come home again, but she had turned to Hei to ask him about being his comrade and companion. Hei had told her that she had to decide if she wanted to remain as Yin or what. Kastinen then made his plea once more to Kirsi, but she placed her finger on his lips and corrected him because her name is now Yin. With Yin having made her decision, Hei knocked out Kastinen with an electrical shock, and Yin had used her finger to push up the corner of her mouth to form a half-smile.
Although good deal of Yin’s past is revealed here, including what happened to both her mother and father, interestingly enough, nothing was said about how Yin actually became a Doll and joined the Organization. Instead, this episode has Yin redeveloping some of her emotions and getting close to Hei (though you could argue that she was already doing that with how she saved him and how she had held his hand back in episode six). Perhaps there will be a future arc that covers how Hei, Mao, Yin, and Huang came together as a group. I also wonder how big a role Yin will ultimately play in the storyline, since it seems the Organization cares about what happens to her (at least in terms of potentially leaking information) and the entire ED sequence is devoted to her.
Overall, I think Darker than BLACK is once again getting better and better every arc. This was the case early on, but the first Kurasawa Gai arc and Misaki’s arc weren’t quite as good. These past two arcs have once again engaged me into the story, and I really can’t wait to see next week, which will feature both Amber and November 11’s group.
