After the devastation of World War 3, a new VRMMO called Callixtus was released, offering players a chance to earn real-world credits for exploration, grand battles, and navigating its complex social hierarchy. Upon Reina''''s arrival at the esteemed Seyapporon Academy, the VRMMO became a part of the school''''s learning core, categorizing students'''' leadership potential based on their actions and influence in-game. In a world of war, politics, developing magic and mythical weapons, a prophecy of ‘Holy Knights’ emerges to battle a new enemy and their monstrous creations. Reina plans to challenge it all and push the game''''s realism to its limits, no matter the consequences.
