The Elemental Witch's Guide to Salvation

Reincarnated in a different world where everyone has a "panel", plus lost 10 years of memory. I thought it was a standard start, until I saw the "Notes" column on my panel, and the bright "Devil King" made my eyesight go dark. How could I, an elemental mage who just wanted to change jobs, upgrade, and retrieve my lost memories, become the Demon King? This is the prison plane "Phantom Moon" wrapped in elemental chaos. The path to ascension is cut off, and all living beings are prisoners. The prophecy whispers at this moment that the old era is coming to an end—— "Chaos is coming, and the endless day is also the beginning of eternal night. Only those who recast the truth with lies and ignite the third sun on reality can change the order, end reincarnation, break the prison, and let the world usher in a real future."
