Mother gently rocked the baby in her arms, quietly reading a story to him so that he would fall asleep.

"In the Dark Times, 3,000 years ago, when demons were still attacking human cities, four people went on a campaign against the Demon King. The great founder of the magic tower, Asta, the wise and brave mage; Carefree, but sweet archer and elementalist, Dynamica; the mighty and strong tank Rock, the first guild master of the Mercenary guild; And last but not least, the great and just master of the sword Jonas, the one who eventually pierced the heart of the demon king with a sword..."

The baby made faces at her story, but she was just giggling, thinking that her baby was curious and interested. But in fact, this baby, which you are now, was going crazy from the wrongness of what is written in the book. Asta? This woman is just a pyromaniac and a smoker, and she used this 'magic tower' that she built as a storage room for unnecessary magical reagents. Dynamica? It wasn't pride, but simple racism. Rock? A jock with one twist and just a fighting maniac who could not live without the sight of blood and gathered people around him as well. Jonas... He tricked you and everyone. He really looked like a model hero, but inside he's a manipulative and self-centered bastard.

However, there wasn't one in this book, it was five heroes, not four. You were with them. But right at the entrance to the demon king's room, when you were betrayed and killed by those you called friends. 'Heroes'. That's when you realized what kind of people they really are.

What else? You are a descendant of the very "hero" Jonas, who even mentally mocked you before finishing you off. But the worst part is that no one knows about their sins and considers them masters and heroes. But you too, be the one who also made a significant contribution to the cause and was their "fifth friend" did not know.
