Synopsis [Saga of the Eternal Heroes] – An Action RPG game where six chosen Heroes appear during every era in order to repeatedly seal the immortal Demon King, and prevent his forces of Darkness from taking over the world! It was a usual holiday, and I was casually playing this boring game that I bought thanks to my co-worker's useless recommendation… …but who knew that someone would suddenly make me transmigrate into this game? And that too as a freaking Demon King…?! What to expect   - A mentally broken guy nearing middle-age with a mysterious past getting summoned to another world by a Devil.   - Overpowered main character (Relative to his main opponents - The Heroes, who can also level-up like the protagonist).   - Not your typical, useless academy jargon. This academy will actually teach some useful stuff.   - Unique Magic/Spellcasting system to support the story.   - Side characters with actual backstories and depth.
