Prologue: The Ashes of a Thousand Fronts

The End and its oblivion army has officially declared invasion across the entire universe for the preparation of the total erasure of the Multiverse to bring about true order through silence as the second stage of the war begins. The Multiverse Defenders, once battered and almost falling into despair, was strengthened again with the return of Twilight Sparkle, ready to halt the total oblivion, and with the aid of new allies and friends like Sailor Saturn and the Frontier Squad members such as Naruto Uzumaki, Tanjiro Kamado, Sailor Moon, Tuxedo Mask, Shinobu Kocho, Giyu Tomioka, and the other Hashiras, Zenitsu, Nezuko, Inosuke, Deku, and many more.

However, The End's loyal apprentices are not ready to give up anytime and determined to erase the hope and heroism while also trying to hunt down for the fragments of the ancient legendary Multiverse relic, the Astral Eternity Core, seeking its ultimate powers and new evolution forms for a nefarious end.

The Multiverse now hangs in the balance and holding its breath as the Multiverse Defenders fights back against the new forces of oblivion and darkness. It is the second arc to the Heroes of the Multiverse: Frontiers before its conclusion with the finale arc, The Last Heroic Stand, coming next year of 2026.

NOTE: Just like the first arc, it was rated PG-13 for grittier action, violence, some brutal moments, and other things that may not be suitable to younger readers unlike the Battle of the Cosmic Multiverse's PG rating.
