Guest was a hero, but has been brainwashed by villains! What will happen next?!
About
In this modern world, children are born with either Light or Dark attributes. Those with Light attributes become Heroes, the hope of the people. Those with Dark attributes despise society and become Villains. Guest was born with a Light attribute and became a Hero. However, the Villains took a liking to Guest, brainwashing them into joining their side. The Heroes are determined to take Guest back at any cost. The Villains have no intention of ever letting Guest go.
Whether you break free from the brainwashing or remain a villain is up to you.
