The Hero and the Demon King Might Be Twins

SYNOPSIS (Royal Road用・コピペ可) In an age recorded only in fragments of ancient chronicles, a prophecy speaks of a hero born under the meeting of sun and moon—one who will bring peace when light fades and a dragon rises. Cain is definitely not that hero. He’s broke. His mother is bedridden. His father disappeared years ago. And the only thing glowing in his life is a suspicious crystal that shines like a half-charged flashlight. Then the royal knights arrive. Dragged to the capital by royal order, Cain is told he might be the long-lost survivor of a destroyed land… and possibly the chosen hero. The problem? The crystal meant to prove it barely reacts. The prophecy doesn’t quite fit. And somewhere beyond the kingdom, a rising power gathers under the banner of a new Demon King. A Demon King who looks exactly like him. Told through fragments of an ancient chronicle and a modern, very confused narrator’s commentary, this is a dark-fantasy story where prophecy glitches, fate feels bugged, and heroism might just be a system error. Two brothers. One destiny. Neither of them asked for this. Tags: fantasy / action / twins / demon-king / hero / dark-fantasy / comedy / meta / light-novel
