"You're not out here to claim my domain, are you?"
Eren didn't have to answer Argo's question. The latter started explaining something to him with passion even before receiving a response from him.
"You gotta listen to me, boss. I have done you no harm, have I?
This Prince is always loyal to the throne…
I'mma spill the beans, boss... Those bastards... they be snitching behind your back thinkin' they are the shits… but I did no such thing like that… Uh hun!
No sir… This Prince always working hard… putting in the work. Earning his keep.
This Prince is always looking for your best interests… I even interfered with the cause-and-effect fabric of reality, hoping to meet you.
We… are a team, boss. Knowwhatimsayin! Those snitches will…"
For some reason, Argo was agitated after his consciousness was abruptly summoned to this place. Eren raised his hand to stop him from speaking up.
"Slow down, you fat bird. Nobody's after your domain or whatever. I just want the Sin Series Mark from you. You can grant me that in your current form, right?"
Argo opened his mouth to speak. But he closed it right away after processing what Eren wanted from him. Laughing, he gave him affirmation.
"Hahaha. I knew we were solid like that.
Aight. Aight. I gotchu.
One hot and crisp Mark of the Seven Sins coming right up. As a matter of fact… I'mma make it so that we both get to share the Domain of Gluttony."
Argo– or Beelzebub in his current form– put Eren down in the center of the Pentastar array. He then closed his eyes before starting to chant something in his demonic tongue.
Eren subconsciously morphed into his white-haired form. He closed his eyes and let the array's active runes climb onto him like live serpents.
Eren's existing tribal tattoos became visible and active under the influence of the Pentastar array. The newly climbed runes started mixing with Eren's existing runic tattoos.
Eren was tied to another Sin Series Plane. He possessed an ability as a result of that bond. And he knew how to use his newly acquired Ability as soon as he received it.
Argo didn't have to do much. He just became a medium to connect Eren with the Plane of Gluttony. The Plane of Gluttony readily accepted Eren. In fact, Eren felt like he could take over the Plane's Authority from Beelzebub if he wished for it.
Only now did the butcher realize why Argo or Beelzebub was nervous around him. He was fearing that his position as the ruler of the Plane might get taken away from him if Eren just wished for it through the connection.
The butcher didn't understand what ruling one of the Seven Sins of Planes meant or what its consequences would be. But he didn't want to find out. At least not yet.
He didn't want to rile up other Demon Princes because he didn't know if they would be as cooperative with him as Beelzebub. It was better to keep Beelzebub as the ruler of Gluttony and grow silently than to attract attention by removing him from his position.
Eren could also guess that other Demon Princes might attack Beelzebub right away if they find out he had lost control of his plane. The butcher would be their next target.
Eren didn't want to lose his valuable follower from the rest of the Demon Princes because of his greed for power. He might be the only friendly Demon Prince among them for all he knew.
The greed for power almost overwhelmed Eren at the time of signing the Faustian Contract. However, he didn't let that greed blind him. The Sins were supposed to be conquered anyway. The man's actions were not supposed to be driven by them, living him astray.
Eren didn't challenge Beelzebub's Authority at the time of the demonic ritual. He let the Lord of Flyers stay as the ruler of his Plane and shared some of his authority over the Plane.
It didn't take long before the Faustian contract was established.
Argo was all smiles when the ritual was completed. He wanted to chat some more with Eren about various topics. Unfortunately, he could not remain attached to his stone vessel after the demonic ceremony was over. His consciousness was sent back to where it came from, making the statue assume its previous form.
The activity inside the Pentastar array died down when Eren opened his eyes. The butcher couldn't help but smile after realizing that he had received another Sin Series Ability. That too with the help of his demon beast.
He had to admit that the Sin Series Abilities were his most powerful Trump cards. The more he had them in his arsenal the better it was for him. Even adding one of these Abilities felt like he had progressed by leaps and bounds as a ranker.
Mark of the Seven Sins- Domain of Gluttony.
Much like his Sin of Wrath, this was also a domain attack. Eren felt that Beelzebub was not talking strictly about domain-type attacks when he asked the butcher if he was after his domain. It seemed that gaining access to these domain-type attacks was an indication of a larger picture.
Eren remembered what Alephee had said to him earlier before he entered Sansara World. The Faustian Contracts for the Sin Series Marks Purgatory had given him were signed between him and the Sin Planes.
Meaning there was no demon involved in acting as the mediator.
Eren had practically challenged the Demon Prince of Wrath when he established the Faustian Contract with the Plane of Wrath directly. Apparently, the Plane did not respect its current ruler as much when Eren established its link with it.
Thus, the demon soul fragment that had overtaken Demonmir called Eren the usurper of his domain and felt threatened by him.
However, Eren was not able to connect with the Plane of Gluttony directly this time. In truth, Beelzebub only served as an intermediary, allowing him to obtain the Sin Series Mark associated with it.
The lord of the Flyers was still the ruler of the Plane. However, the Faustian Contract ensured that Eren could use some of the plane-bound powers the Demon Prince was privy to. What's more? The butcher would be able to unlock more of such plane-bound powers and Abilities as he progressed further in his ranking journey.
