Ekubo, a self-proclaimed upper-class evil spirit, bears red circles on his cheeks and manifests as a wispy smoke cloud with sporadic limbs. His face features an overly detailed human-like appearance marked by a prominent nose and lips. His earliest memory begins post-mortem in a cemetery, devoid of human-life recollection; he once led a spirit gang until narrowly escaping exorcism by Mogami. Initially driven by godhood ambitions, Ekubo manipulated followers through hypnotic smile masks, founding the LOL cult to amass worship. After Mob dismantled the cult and defeated him, Ekubo feigned partnership to eventually possess Mob. His plan shifted as he aligned with Mob, transitioning from exploiting Mob’s power for personal godhood to aspiring to make Mob a god instead. Brash and humorous—evident in nicknames like "Shige-chan"—Ekubo displays perceptiveness, identifying psychological complexes in others, such as Teru’s superiority issues and Ritsu’s inferiority struggles. His development reveals gradual genuine care: he warned Mob about a fake love letter, corrected misconceptions about popularity, and during a house fire, prioritized Mob’s emotional well-being by searching for signs of struggle and shielding him from traumatic sights. Loyalty tests defined critical arcs: against Mogami, Ekubo possessed Mob’s body for protection, fought Mogami despite being outmatched, and entered Mogami’s mental world to restore Mob’s memories. In the Divine Tree Arc, after gaining godlike powers and brainwashing the city, Ekubo dismissed Mob’s opposition but acknowledged Mob’s resolve when halted. Mob’s intervention spurred Ekubo to express admiration for his humility and strength, cementing redemption. Abilities include possession—ineffective on powerful psychics without consent—mass hypnosis, energy projection like the Wraither Beam, and amplifying his host’s physical capabilities. Post-redemption, he operates as a self-proclaimed spiritual advisor at Spirits & Such, offering insights on psychic phenomena and spirits.
