The figure presents Ekubo as a striking ethereal presence spiraling around Kageyama Shigeo, who stands in his characteristic calm stance with one fist lightly clenched and a faint, controlled glow around his aura. Reigen Arataka is positioned slightly behind, captured in a confident, mentor-like pose with a crisp suit and a welcoming smile. Ekubo's form is sculpted with a mix of opaque plastic for the body and translucent resin accents to suggest spectral energy, giving the impression that the spirit is hovering between dimensions. Shigeo's hair and hoodie are carefully wired with delicate folds and texture, while Reigen's jacket shows precise line work. The base resembles a small urban street corner, with a textured pavement and subtle weathering that anchors the trio in a moment of tension and camaraderie. Overall, the diorama captures the balance of power, mentorship, and friendship that defines the series.

In the Mob Psycho 100 narrative, Kageyama Shigeo (Mob) begins as a prodigiously powerful yet emotionally restrained boy learning how to control his gift. Ekubo appears as a restless spirit whose motives shift between mischief and genuine longing for recognition, creating conflicts that force Mob to test the limits of his growing self-control. Reigen Arataka acts as a flawed but well-meaning mentor, guiding Mob through practical strategies while teaching him that true strength comes from balance, compassion, and self-respect rather than raw power alone. Ekubo's presence intensifies the moral questions at the heart of the story, pushing Mob to decide whether to exorcise or to understand the spirit. The trio's dynamic: Mob's quiet resolve, Reigen's streetwise wisdom, and Ekubo's unpredictable energy drives key arcs about identity, friendship, and the responsibilities that accompany extraordinary abilities. Through humor, danger, and quiet moments of reflection, the characters learn to navigate fame, fear, and the cost of power.
