Max, a curious and empathetic young boy traveling with companions, becomes the key to awakening Jirachi—a Mythical Pokémon emerging with the Millennium Comet—during a festival celebrating its once-in-a-millennium arrival. His unique ability to hear Jirachi’s voice through its crystalline cocoon designates him as the destined partner, bound to the comet’s cycle and the legend of the Pokémon’s wish-granting power. Their bond drives his arc, blending childlike enthusiasm with impulsive choices. After Jirachi awakens, Max tests its powers by wishing for candy, inadvertently triggering chaos as snacks teleport from nearby stalls—a mishap underscoring his naivety and the need to grasp the responsibility behind Jirachi’s magic. His protectiveness flares when confronting external threats like Butler, a magician plotting to exploit Jirachi’s energy to revive a rampaging entity mimicking Groudon. Interactions with his sister, May, oscillate between playful rivalry—teasing and squabbles—and quiet affection, most evident when her lullaby, tied to their shared past, soothes Jirachi. The fleeting seven-day bond with the Pokémon forces Max to confront impermanence, grappling with impending loss while learning to sustain connections beyond physical presence through a mentor’s guidance. Amid crises, his resilience shines. He aids allies in thwarting Butler’s artificial Groudon, collaborating to drain its energy and free absorbed victims, reinforcing trust and unity. His journey balances wide-eyed wonder with maturing awareness of consequences, the experience etching into him the value of fleeting moments and the profound weight of wishes.
