Reborn Hell League

Reborn Hell League (生まれ変わっ地獄連盟 Umarekawa Jigoku Renmei) is a faction that comprises of only demons, Etherious to be precise. It is led by an Etherious named Dentrix. The main team that is known in this league is the Seven Satanic Sins  (七つ悪魔の罪 Nanatsu Tsumi Akuma), with their leader, Regento. The Reborn Hell League is a faction along with Occultus, which is led by the Thirteen Demon Lords, Nightmare Wing, Demon Spade, and the Legendary Tartaros.

Outcome: Success
This mission was based on finding the seven Etherious demons that would be perfect for the elite team of the faction, the Seven Diabolical Sins. But the leader, Regento, and the other six members were all separated in Ishgar and Alakitasia, and they were hard to beat for Dentrix, the leader of the Reborn Hell League.

Outcome: Success
This mission was based on how they would find their hideout and where to live. Luckily, Dentrix found a lost island that was hidden for millions of years, that even Dragons couldn't find during the Dragon civil war 400 years ago. He found some Etherious there also and decide to name the country,'Cobaltius,' because the main resource was cobalt, an element that gives all Etherious infinite power for only a short time. The country is as large as 75% of Fiore.

Outcome: Failure
This mission was based on using the Gigantic Ultra-Luminous Ether-Extraction Explosive Lacrima, also known as GULE-EEL, to destroy the whole continent and wipe out its existence. It was a failure because Project GULE-EEL was stopped by the infamous guild of Fiore, Twilight Phoenix.

Outcome: Success
This mission is based on the rebuilding of the Reborn Hell League after its loss to Twilight Phoenix. The team was successful in rebuilding the faction once again. Now, their only problem is what kind of havoc they can cause.

Outcome: Ongoing (In Secret)
This mission is based on the attack on S.H.I.E.L.D, an association that has the goal of eradicating every demon, whether Etherious or False. The rest of the details are unknown.
