A high school boy named Zach always loves playing games, especially his favorite game, Swords of Heroes, a game about a hero who wanted to save the world. But that's not the reason it's his favorite; it's because one of the characters named Zach, who has the same name as him, this character is loving, caring, and, most importantly, always listening to reason, unlike the hero who only wants to hack and slash. Everyone sees Zach as nothing but a coward and a fool, being hated by his own sister and everyone around him.
One day, while walking home, Zach was watching a live stream of one of the developers of the swords of heroes explaining all their future updates and their plans for the games, but suddenly everything went black, and he woke up in an unknown room. When he looked in the mirror, he saw that he was his favorite character from the sword of heroes.
