This is a high-stakes "Second Chance" epic that reimagines the Tensura universe through the eyes of an omnipotent Rimuru Tempest. Bored with the absolute peace of his original timeline, Rimuru leaves a parallel existence to rule in his stead and travels back to the Dawn of Creation. Arriving as the Void King Dragon, the literal embodiment of "Nothingness," he balances the "Everything" of the Star King Dragon, Veldanava. Unlike the original story, Rimuru operates from the shadows for eons, subtly fixing the tragedies of the past. He reunites the True Dragon sisters, saves Veldanava and Lucia from their fated deaths, and mentors a young Guy Crimson and Rudra. As the timeline shifts into the modern era, Rimuru "reincarnates" as a slime to play the game from the ground up, but with the secret support of his wives-Ciel, Chloe, and Velzard. Now, as an Awakened Demon Lord who has reclaimed his seat as the Second Pillar of the Council, Rimuru leads a united front of Gods, Dragons, and Monsters to crush the looming threat of the Eastern Empire and the Manas Michael, ensuring a future where his family and his nation can never be destroyed again. Would you like to see a dramatic finale where Rimuru and the united Council finally face off against the Eastern Empire's invasion?

There are many worlds within the multiverse, but two in particular are of great interest to readers. In one world, the Holy Britannian Empire seeks to conquer everything, and Lelouch, an exiled prince of the empire, strives to dismantle it while dealing with personal pain, strategic challenges, and significant losses.
