The Mirror World Projection first manifests in Volume 2 as a hauntingly perfect reflection of reality that only Beyonders can perceive, where ordinary humans exist merely as sleeping illusions. This dimension serves as both sanctuary and battlefield, allowing Klein Moretti to manipulate reflections and conceal his identity from the Tarot Club and external threats. Over the course of the series, the Mirror World evolves from a passive sanctuary into an active battleground, where Klein's mastery over it becomes crucial for his ascension and survival against increasingly powerful foes.
