Imagine receiving a box that grants any wish. This is the premise behind The Empty Box and Zeroth Maria, a light novel that initially appears simple but ultimately reveals a deeply psychological and emotionally resonant story that lingers in the mind. Zeroth Maria, written by Eiji Mikage, delves beyond supernatural mysteries to explore the human condition, examining selfishness and the true cost of happiness.

The story begins with Kazuki Hoshino, a high school student who cherishes his routine and the certainty it brings. His life takes a dramatic turn when he encounters a mysterious figure who declares, “Nice to meet you. I’m here to ruin your life.” This encounter sets off a psychological battle fueled by emotions and fantastical situations, where reality is manipulated to fulfill the desires of those who possess one of the aptly named Boxes—devices capable of granting any wish, no matter how impossible or selfish.

Zeroth Maria fundamentally explores the conflict between human principles and values. Each arc introduces new characters who acquire a Box and manipulate reality to suit their desires. However, Mikage ensures that the story goes beyond the power fantasy, prompting readers to contemplate the consequences of their wishes. A wish comes at a cost; the Boxes amplify the darkness within individuals. Throughout the novel, readers are confronted with moral dilemmas, questioning whether it’s acceptable to seek a perfect, unchanging life, how far one would go to protect what they love, and the ultimate question—can one truly be themselves in a world of limitless possibilities?

The interactions between the characters are the throbbing heart of this novel. In this way, Kazuki proves to be one of the most interesting main characters in light novels not due to being excessively powerful or brilliantly smart in realms ordinary people cannot emulate, but due to being an ordinary person, to the point of stubbornness. His wish to live a normal life is opposed to the existence of Aya Otonashi, who has lived several loops of time and tragedies and has become hardened but still seeks a meaning. Their encounters are the emotional spine in the story: acerbic, touching and heartbreaking, all in a pinch. Aya is definitely one of the most interesting female leads in the medium: mysterious, flawed and very much human despite the cold shell.

Zeroth Maria is an exceptional work of writing and structure. The author masterfully combines mystery, psychological tension, and romance, making the story a delightful read. Each arc is more intricate than the last, featuring increasingly deadly and intriguing Boxes. However, the story never loses its human touch. The twists are not mere shock value; they are carefully foreshadowed and character-driven. When revelations occur, they are devastatingly impactful, revealing the motivations behind the characters’ actions, even when they are monstrous.

Zeroth Maria is a fundamental exploration of desire and consequence. It challenges the notion of a conventional life that leads to a happily ever after by posing the question of what true happiness entails. Can it be something that can be granted as a wish? Or is it something that must be constructed through struggle, failure, and pain? These questions linger long after the final pages are turned. The sixth book stands as one of the most effective concluding books I’ve ever read, a captivating blend of hopelessness, loveliness, and a sweet farewell.

Eiji Mikage’s writing is sharp, philosophical, and emotionally charged. While it may occasionally feel heavy, this is precisely what sets it apart from most light novels. It’s not a power fantasy; instead, it’s a thought experiment that delves into the depths of the human heart and mind.

“The Empty Box” and “Zeroth Maria” are among the few masterpieces of the light novel genre. They present a thought-provoking exploration of philosophy, psychology, and human emotions. Unlike other light novels that may sugarcoat life or offer simplistic advice, these works challenge readers to confront their own desires and actions. They ask us to consider what we would do if we possessed the power to grant any wish.

Beyond the story of Boxes and wishes, “The Empty Box” and “Zeroth Maria” are a profound exploration of human nature. They examine our weaknesses, dreams, and shadows, and they reveal the price of attempting to avoid the very essence of what makes life human.
