Fallen Dark lord

Battle against Old Satan Faction

[scene: Underworld]

Diodora has taken Asia and left with his peerage. Due to the shock and surprise the Old Satan Faction attacked. Rias then tried got every one of her peerage out of there. However a bunch of devil of the Old Satan faction started attacking them. Due to their training, Rias and her peerage was holding their own against them.

Issei with Ascalon back, fought off the devils as he summoned his amour to make this process go quicker. As he was fighting against the a flash of white came by and knocked some of them back. Issei looked to see Vali in his amour.

Issei: Vali?

Vali: We can settle our fight later, my rival. However let's take care of this old Devil.

Issei then smirks as both he and Vali let their aura out, as they stared down a horde of Devil.

Issei: Right!!

Both Dragon Emperors that charged right into battle. This has survivors from the Great War to have flashbacks to said war. However this time both the Red and White dragons were working together.

Kiba and Xenovia drew their swords. Kiba, his Holy Devil Sword, Xenovia, with Durandal, both knights of Rias Germory got ready, as the other knights from the other peerage then did the same thing and drew their weapons. Which motivated both of Sirzechs knights to join in.

Koneko and Gasper then worked together as they fought the old Satan Faction with the help of the devils from the other Devil heir's peerages. Gasper was using his sacred gear to stop them in place, with other bishops casting their magics and various other spells. Allowing the rookes to land powerful hits. Koneko especially as she used her Senjusts and Youjutsu, which she learned the latter from her sister Kuroka. To serious hurt the devil due to the property of her powers.

Akeno was using her light magic and her holy Lightning against the devils of the old Satan Faction. She was handling herself well. She then noticed a devil about to attack at her from behind. She couldn't move fast enough to block it, however she didn't have to. A shadow figure came out of her shadow and killed the devil. The shadow then changed to reveal who it really is.

Akeno: (Y/n)?

(Y/n): We'll talk after the tournament, however we got to take care of.

(Y/n) then summoned a dark blade, befitting for his position as the Dark Lord, Akeno then did something that surprised (Y/n) and the Fallen Angel's leaders. She summoned some holy lightning and then brought it to her hand to turn it to a holy lightning spear. Both hybrids then fought against the devils they were against. Akeno used her light and her holy lightning to cause severe pain to them as (Y/n) used his swordsmanship, Dark Light magic and transformations to dominate the battlefield.

Some of the leaders of the Old Satan Faction attacked the current leaders. However they were underestimating them as the current Devil Kings showed how ruthless they can truly be. Sirzechs using his power of destruction to destroy the Old Satan Devils, as Serafall Froze them solid with little to no remorse. Show she was someone to take lightly.

During the Battle Odin also helps Rias and her peerage by using some Asgardian magic to summon the Valkyries to help and help empower the peerage and both Dragon Emperor. He looked towards both the Light and Dark Lord, he noticed that the Light Lord Jesus wasn't doing much fighting, however he did defend him self and knocked the devils unconscious. Then he looked towards the Dark Lord (Y/n) to see him dominating the battlefield, when he saw (Y/n) transformation and how powerful he is went he lets loose a bit. He decided not to empower them as they were handling themselves well.

Odin: 'I have to make sure that Loki doesn't learn anything from the Dark Lord, those are some powerful transformations he has, Loki will be more of a problem to deal with if he has access to those.

As the battle continues, Sirzechs then told the Germory Peerage to pursue Diodora, and get their bishop back. The Germory peerage then followed the order of the current Devil King Lucifer and make their way towards Diodora castle where he is with their stolen Bishop Asia.
