"I — Azazel, and Barakiel were currently together in the capital city of the Devils’ side in the Maou’s territory, Lilith. Within the conference room in the city which belonged to the Maou, a summit was being held (Devils’ side, Fallen Angels’ side), to discuss the response to Trihexa. Sirzechs did not attend because he had other urgent matters to attend to. The Governor of my side, Shemhazai, was issuing commands at the Grigori Institute. Five days ago, after Trihexa revived, it destroyed the main facilities of the Fallen Angels’ Grigori Institute first, after which, it was transported to Heaven. It also devastated the First Heaven which acted as a frontline base, all the way up to the Sixth Heaven, the core area where the Seraphs resided. Those who were working at the main facilities of the Grigori, as well as the Angels who fought against Trihexa in Heaven had essentially been killed. The Cadres of my side — Sahariel and Penemue had both been severely injured, while their older subordinates had also died in battle. The damage which occurred in Heaven was even more serious. Three of the Seraphs had been seriously injured; Raphael had lost a leg while Uriel had lost an eye and an arm. Several of the Angels who had existed since ancient times had died. The final and uppermost Seventh Heaven was successfully defended, and the [System] which was left behind by the God of the Bible had been protected. …However, the sacrifices which were made for that were simply too great.

At that time, in the centre of the round table in the conference room, a video of that battle was played. The gigantic beast mercilessly sprayed out flames from its seven heads. The facilities of the Grigori, as well as the surrounding terrain were blown away in an instant. What happened in Heaven was an equally horrific and agonising sight. The bursts of fire that Trihexa spat out penetrated from the First Heaven up to the Third Heaven. The scene of Heaven was horribly tragic as it looked as though it had turned into a burning hell. Alongside it were the fake Sekiryuutei and mass-produced Evil Dragons, which caused even further damage. The leaders of this were the legendary Evil Dragons who were second to none, Aži Dahāka and Apophis. The extent to which their attacks went was even greater than what Rizevim had done. …Many black feathers and white feathers had fallen…. Even Michael was unable to take on Trihexa, and he had been defeated. That guy wasn’t in this conference room because he was still being treated, while also repairing the damage that was done to Heaven. After the main facilities of the Grigori and Heaven had been successively destroyed, the Imperial Beast of the Apocalypse transported again. On the third day after Trihexa had revived, the place that it had set its eyes on was—."
