The Story So Far...

10/17 - Mephisto tells Gyro about some entity that is stalking Arietta and asks him to keep an eye on her, because of her connection to Rin. Although he has no plans to tell Rin, he doesn't put the same restriction on Gyro. Gyro decides not to tell Rin.

11/03 - Arietta is targeted by a coordinated group of mongrels for the first time. Erza saves her. Arietta notices these kinds of attacks becoming more frequent. As a result, she starts trying to blend in more, covering her hair and face when she goes out.

12/01 - Arietta mentions the mugging to Gyro, who suggests she start carrying a gun, or invest in a digital skin for staying safe when walking home. Arietta notices some of the men from that night watching them at the restaurant they're in, but she and Gyro have public sex in front of them anyway because yolo. This hook-up is recorded and posted online, increasing her harassment.

12/10 - Mephisto checks in with Gyro and learns it's possibly someone with the black market behind the attacks. Mephisto implies he needs to be more proactive, dropping cryptic hints at him implying he might have some suspicious patients at his clinic.

1/05 - Killua notices someone stalking Arietta after work, and reveals it to be a patient of hers named Hank. Killua lets him go, thinking he's harmless. But the next night he confirms Hank is working for someone, but doesn't seem too enthused about the job. In the end, Killua spares Hank and secures himself a meeting with the man behind all of this, who claims to be looking for revenge against Liger for the sake of the people of Ceres. Killua learns of a possible connection between this man and an elite named Reggie Kray, who was killed during the Her Bay incident, and later not revived due to his Black Market ties. The man had very severe facial scars that looked like claw marks running down the side of his face.

1/06 - Killua confronts Arietta and they discuss the possibilities of who could be behind it all. She tells him about what the Market did to her, and that she remembers a man with facial scars like Reggie Kray, and confirms that they shared a last name.

2/10 - Jae-Ha saves Arietta when he finds her being tortured by her hacked collar. She tells him what little she knows of the man in the mask.
-Shal saves her when the same thing happens again, only this time the men involved give chase.
-Arietta is assaulted by her collar again and Law saves her. He remembers the faces of the men who were watching. She asks him not to tell Rin about what's happening.

2/12 - Arietta suspects Rin might actually be the one behind her collar hurting her without knowing because of his hallucinations, and actually appears to be afraid of him.

2/16 - Finally, the collar torture happens in front of Killua, and he kills the man controlling her collar. using the palm reader owned by the dead man, Killua speaks to the man in the mask and calls him Reggie, but the man denies it, calling himself "a specter here to carry out (Reggie's) final wishes".

2/21 - Mephisto meets Killua and after they agree to become allies, he off-hand mentions a magic key that was stolen, but he doesn't seem worried about it.

2/24 - Rin receives a threatening message from the masked man, taunting him with videos of Arietta being tortured. Rin rushes to Arietta's workplace and they get into an argument, that ends with Arietta once more being tortured by her collar. When Rin finds the one responsible, he threatens him before letting him go. The man goes on to tell other lackeys about how terrifying Rin is, and they back off.

2/25 - Killua receives a message from Hank regarding a man with a bounty on his head named only Kray, who was locked in Kantoi for the past two years for identity theft. He doesn't resemble the man who was killed in Her Bay. He goes on to tell Killua about Rin's rampage a day earlier.

2/25 - Killua checks in on Arietta. He reveals he knows the location of the bar the masked man frequents, and Arietta tells him she got a new collar so the man can't hack it anymore.

2/26 - Arietta tells Gyro about what's been going on.

3/28 - Rin and Killua arrange to confront the masked man at the bar he frequents in Ceres, while Arietta and Liger remain on standby not too far away. When they get there, they find Mephisto, who tells them he's here to confront the man who stole his magic key. After explaining the situation, Rin asks for Mephisto's help. Shortly after, Killua receives a phone call from Hank, who tells him that the man named Kray with a bounty on his head is Ron Kray -- Reggie Kray's fraternal twin brother, seeking revenge for his death. The bartender mentions that their regular, a man who wears a mask, is late tonight. Mephisto follows up the bartender by wondering outloud whether the man had something else important to do... and then asks Rin if there isn't something important he should be doing instead. When Rin confronts him about what he knows, he offers to teleport him and Killua to where Arietta is.

As this is happening, Liger's collar suddenly goes berserk, causing him to go on a rampage. With the help of Arietta and Shima, Gyro manages to calm the beast. During the scuttle, Law and Mihai spot a sniper on the roof, and after stripping him of his belongings, they take chase. Among those belongings is a remote control that allows them to indirectly remove the collar from Liger's neck, returning his powers. Rin and Killua will show up during the aftermath of returning Liger's powers.

During the ensuing chase, Law and Mihai learn the man is using a strange power to travel around Amoi: an old key strapped to a device on his wrist, allowing him to turn any door he touches into a portal that takes him somewhere randomly around Amoi. Ultimately, they corner him in the very same bar where Killua and Rin had just left. Just when the two appear to restrain him, Mephisto steps in and captures the man before he can explain himself. In the process, the man reveals some sort of connection to Mephisto, implying that he knows him and apparently is afraid of him. Mephisto thanks the two for their help in returning his key to him, and tells them they ought to let Arietta know that she no longer has to worry about her stalker.

During an exchange, Mihai gets mad and shoots Mephisto in the face, from which he instantly recovers. To assuage their suspicions, Mephisto tells them about his connection to Rin and the key that was stolen from him. He denies any connection to the stalker, further explaining that if they're so worried, they should just ask Rin himself. He then teleports them back to the scene with Liger, whether they ask to go or not.

The Reveal

Although no one got quite close enough to figuring it out, everything here was actually a carefully orchestrated plot by Mephisto to test a number of his chosen allies' and potential allies abilities.

Ron and Reggie Kray were criminals who stole identities to siphon large amounts of money off of elites. Two years prior to Tanagura's opening, Ron took the fall for Reggie's crimes and was sentenced to ten years in Kantoi, leaving Reggie alone. Shortly before the castes switched, Reggie was mauled by Liger in Ceres. His face was heavily disfigured, and he put himself in debt with the market to try and pay for extensive plastic surgery. In the end, the surgery was botched, and Reggie became obsessed with getting revenge against the monster and the girl who owned it. Completely consumed with madness, he took part in Arietta's torture when she was kidnapped by the market a few months later. A few months after that, he was in turn killed by Arietta during the battle at Her Bay. Because of his extensive criminal record, the authorities decided he wouldn't be revived.

After Iria took over Tanagura, the criminals in Kantoi were released -- including Ron, who learned about what happened to his brother and decided to take up his final wish for revenge. He took on Reggie's identity and began hunting Arietta down.

But before he could get very far, Mephisto became aware that a certain man was targeting Arietta. He immediately intervened and appeared before Ron as a demon offering a deal, saying he could have his revenge as long as he agreed to do it on Mephisto's terms. Ron needed to build a small following within the Market and secure control over Liger's collar from the higher ups, while slowly fostering unrest in Arietta's life without giving himself away. Ron agreed, and began to contract small-time criminals to target her.

Around this time, Mephisto decided to test whether Gyro would be a good ally for his schemes, specifically to see whether he could be manipulated. He told Gyro about Arietta, thinking he'd take an active role in protecting her. Instead, Gyro only gave her a warning, and didn't make any effort to tell anyone else about it. The video taken of the two of them was later used by Ron to recruit more people in harassing her.

Mephisto told Ron to plant someone close to Arietta, and specifically recommended one of her patients, Hank, for the job. Hank was someone Mephisto was keeping an eye on -- despite his undead nature, Arietta's healing abilities still worked on him, implying she could heal injuries that had reached the point of necrosis. And as a demon with a body that is slowly rotting, this was something he wanted to test. Originally Mephisto hoped that Gyro would discover Hank was stalking Arietta, but instead, Killua intervened.

Taking an interest in Killua, Mephisto told Ron nothing, and let him assume he was just another potential crony to recruit for harassing Arietta and Liger. Mephisto took an interest in Killua, which culminated after the failed satellite hi-jacking. Later, when Mephisto met Killua face-to-face, he formally invited him to become his ally and dropped hints regarding the key he gave to Ron. He wanted to test whether Killua would be able to figure it out the connection between Mephisto and Ron.

Around this point, Ron began to act out, frustrated by how much time this was taking. He had created a device that let him instantly travel to 5 specific locations on Amoi from anywhere (rather than a normal magic key, which only leads to a single location), and hacked into Arietta's collar to attack her directly -- this was not part of Mephisto's plan, but it did give him insight in what kind of people Arietta has around her. Shal, Jae-Ha, and Law all appeared on Mephisto's radar, but he had no solid means of tracking them and was unable to follow-up.

Meanwhile, Rin was kidnapped by the Black Market, which caused Mephisto to think twice about continuing to use them for his own purposes -- knowing that if he were caught being involved with the Market, he'd have trouble gaining Rin's trust again. This incident also gave him insight into Arietta, and how easy it would be to manipulate her for his plans on Assiah. At this point, he was committed to bringing both Rin and Arietta back from Amoi.

After deciding it was time to test Rin directly, Mephisto told Ron the best way to get to Arietta would be to taunt Rin. In reality, Mephisto knew this would be the start of Ron's downfall. Prior to this, he ensured that Ron had secured the device to control Liger's collar -- but told him not to use it until the timing was right.

He verified that Rin still won't kill humans, but isn't afraid to use excessive force -- maybe even to a higher degree than he would willingly do back home, threatening to burn down entire buildings for Arietta's sake. Rin gets a B for effort, but a D in terms of not learning about all this earlier (even if it wasn't necessarily his fault).

Mephisto was also behind their final confrontation. Stalking out the bar, Mephisto told Ron that Killua and Rin would likely come looking for him, and laid in wait until that day came. When it did, he made sure Ron would know where to find Arietta and Liger, so Ron could begin his assault. From what Mephisto had seen in previous attacks, he knew someone would come to Arietta's rescue -- but who that would be was not part of his plan. But knowing how weak Ron was without his support, Mephisto was confident they would be able to take Ron down and free Liger from that collar -- which was part of his plan.

In the end, Mephisto rewarded Shima for his involvement, giving him the only real hint regarding his own involvement, knowing Shima would keep it to himself. Killua was confirmed as Best Boy and got an A+ for figuring out Ron's identity and schemes, as well as being able to get the reason for Ron's hatred out of Arietta (also he gets extra credit for actually killing people, Mephisto isn't used to murdershotas). Rin was informed of Ron's capture, further cementing Mephisto's role as Rin's ally -- as well as putting him in Rin and Arietta's debt. Gyro failed in terms of not doing exactly what Mephisto had told him to do, but put himself back in Mephisto's good graces by still managing to help Arietta in the end. Mihai gets a a B+ for being ballsy enough to shoot Mephisto in the face. Law doesn't get a grade yet, but Mephisto is already excited to think he might have found a new ally in him. People who have absolutely zero trust in him are so nostalgic...

And as for Ron, Mephisto will be keeping him suspended in time until further notice, though he'll tell Rin to pass on the message that Arietta is free to decide his fate for herself whenever she is ready.
