## **Summary**

A large-scale conflict that encompassed the entire mythological world as all factions tried to stop the awakened legendary Imperial Beast of Apocalypse; the 666 (Trihexa). This also marks the final battle against Qlippoth.

## **Prelude**

After Team DxD's victory over Rizevim Livan Lucifer at Agreas, it seemed that Qlippoth and the release of the 666 (Trihexa) was thwarted. However, a recording of Rizevim revealed in the case of his death, his soul would be used as the power source to awaken Trihexa. As Trihexa awakened, the two Evil Dragons, Apophis and Aži Dahāka, issued a challenge to Team DxD as they told Team DxD that they would face other in a fight to the death.

## **History**

As Trihexa emerged from its sleep, the Evil Dragons directed it to attack the Grigori headquarters, decimating it and later teleported it to Heaven, where it laid waste to the First Heaven. After that, they lead it to attack the Norse World, with Aži Dahāka attacking using his magic and Apophis darkening the sky and unleashing his *Primordial Water*. The Valkyries and Norse Gods went to defend, with them being assisted by the Hindu Gods and Team DxD. After 3 and a half days of intensive fighting, Trihexa was teleported away, as the Norse World was saved. Sasuke came up with a plan to get defeat Trihexa, Vali and Issei were sent to 'train' inside the Space-Time Realm against Aži and Apep by Sasuke.

Trihexa split itself into seven separate bodies with one heading to the coast of Japan, another heading to the mountainous areas of Europe, one flying in the Dimensional Gap and the rest attacking the various territories of the various mythological factions (Greek, Hindu, Celtic, and Egyptian mythology).

### **Greece**

The Greek front engaged the Trihexa body trying to damage it with both Mashiba's Peerage faced off against the Beast with Thalia using her **Nega-Keraunos** on it while the Greek Gods fought against the Chaos Dragons and mass-produced Evil Dragons.

### **Celtic**

The Celtic front engaged the Trihexa body trying to reach Celtic.

### **Egypt**

The Egyptian front engaged the Trihexa body trying to reach Egypt.

### **Japan**

The Japanese front engaged the Trihexa body trying to reach Japan, with various skilled fighters fighting against the mass-produced Evil Dragons. Xenovia led the attack with her *Cross Crisis* attack as Irina followed her as all of the members of the Occult Research Club join in the battle. Yuuto, Koneko and Ravel worked together as a joined group, as Rias had Issei equip her with **Crimson Extinction Dragonar**, which strengthened her power.

The Sitri peerage joined in as Saji unleashed his black flames, Sona unleashed her water monsters to attack. Akeno and her cousin Suzaku worked together as Akeno summoned her Holy Lightning Dragon to assist the sacred bird, Suzaku. Dulio used his Balance Breaker; **Flagello di Colori del Arcobaleno, Speranza di Briscola**, to alter the weather as he generates countless bubbles which created various weather phenomena inside them, destroying many Chaos Dragons and mass-produced Evil Dragons.

Apophis used the Holy Grail to create more mass-produced Evil Dragons, with Naruto and Sasuke trying to damage Trihexa causing some noticeable damage using **Scorching Halo Hurricane Jet Black Arrow** technique. Crom Cruach and Cao Cao joined the fight, as each killed a vast number of enemies. As the preparation for the Trihexa sealing technique were ready, Cao Cao used *Truth Idea*, which forced the Evil Dragons to move away as it even affected Apophis, who fled the battle. Rossweisse activated the Trihexa sealing technique, stopping its movements as the warriors of the Japanese front began to exterminate the mass-produced Evil Dragons. Issei entrusted Gasper and Valerie with retrieving the Holy Grail as he chased after Apophis in order to fight him.

### **Europe**

The European front engaged the the Trihexa body and the mountain of a certain European country. The fronts vanguards were the Vali Team and Slash/Dog Team along with Kiyomi and Menma. Tobio Ikuse told Vali Lucifer to go fight Aži Dahāka, knowing that Vali's mother lives at the rural part of the country and Vali's desire to protect her. Tobio activated his *Abyss Balance Breaker*; **Perfectus Tenebrae Lykaon et Fortis Densus Laelaps**, as he transformed into a beast of darkness and covered the whole mountain with dark blades, which tore apart the Evil Dragons and Chaos Dragons. Lavinia Reni reassured Vali and began to activate her own Balance Breaker; **Assoluto Argento Mondo**, as Tannin told Vali to be careful about Aži Dahāka's magic. Vali flew to Aži Dahāka's location as the two engaged in combat.

After gaining control of the Holy Grail, which stopped the mass-produced Evil Dragons from being further created Megumi used the Holy Grail to bring Kurai Nara back to life.

Sirzechs assumed his true form as he and Issei engaged Trihexa. However, Trihexa turned into a woman with multiple wings and two horns.

Issei and Sirzechs coordinated their attacks and despite their strongest attacks, they were still unable to inflict any substantial damage due to Trihexa's regeneration, even when Issei's used Ddraig's special flames, *Blazing Inferno of Scorching Flame*. As the backlash from Issei's DxD armor begun to take effect, Ayame and .

Before implementing the strategy, Sirzechs used a hypnosis technique on Grayfia to make her lose consciousness as he wanted her to stay behind to raise their son Millicas, as the peerage transferred the the core into the Isolation Field Barrier.

As the backlash from Issei's DxD armor begun to take effect.

### **Dimensional Gap**

Trihexa split bodies all went to Dimensional Gap due to sensing Ophis and Great Red's power before merging together to become one.

## **Conclusion**

The conflict caused a historic loss of powers from all of the mythologies, especially combat strength of Heaven and the Underworld, which significantly declined; the overall combat strength that The Three Factions worked hard to recover after the War was once again exhausted.

Vali Lucifer (White Dragon Emperor of the Morning Star) and Issei Hyoudou (Red Dragon Emperor of the Blazing Truth) had become acknowledged as future Super Devil candidates.

Due to his contributions during the conflict and various conflicts before, a certain proposal was passed in the upper echelons of the Underworld, as Issei Hyoudou was was nominated for a promotion to become a High-class Devil. Being advocated for a promotion to a high-class Devil within less than a year after reincarnation, was an exception among exceptions that had never occurred in the past.

Due to their participation in two Beast-type wars the Ōtsu-verse Gods made a public announcement that Sasuke Uchiha, Naruto Uzumaki, Kiyomi Uchiha and Menma Namikaze were known as Supreme Devils and respected as such.

To alleviate the tension between the factions and cultivate powerful beings to fight against future threats, the **Azazel Cup** was organized, as a Rating Game tournament in which all factions could compete in.
