A self-proclaimed upper-class evil spirit, Dimple first surfaced as the founder and leader of the (LOL) cult, scheming to achieve godhood worshipped by humanity. He employed cursed smile masks to hypnotize followers into forced laughter and submission. After encountering Shigeo Kageyama and failing to brainwash him, Dimple battled the boy only to be exorcised when Mob unleashed his psychic rage. He reformed the next day, approaching Mob at home to propose an alliance for godhood while secretly plotting to possess Mob's powerful body later. Mob spared him on the condition Dimple refrain from malice. Initially driven by selfish motives and viewing Mob as a tool, Dimple demonstrated sharp perceptiveness, accurately analyzing psychological complexes like Teruki Hanazawa's superiority and Ritsu Kageyama's inferiority toward Mob. He provided tactical support during conflicts—possessing bodies to combat threats like the Dragger, or joining Mob and Reigen against the evil spirit Mogami. In the Mogami arc, recognizing Mogami's power from a past near-exorcism, Dimple possessed Mob's body to protect it during Mob's spiritual journey. When Mob faltered in Mogami's mental world, Dimple entered to help him regain memories and resolve. Dimple's loyalty to Mob gradually deepened. He showed genuine concern during crises, searching for signs of struggle in Mob's burning house and reassuring him about his family's safety. He moderated Mob's misunderstandings, warning about a fake love letter or tempering assumptions about popularity. Dimple grew to admire Mob's humility and principles, acknowledging in battle that hard-earned strength surpassed psychic power. Yet his desire for godhood persisted. During the Divine Tree arc, he secretly absorbed energy from a giant broccoli to amass power, establishing the Psycho Helmet cult and brainwashing citizens. Confronted by Mob, Dimple revealed Mob as the cult's true founder but refused to yield, leading to a battle where Mob destroyed his enhanced form. In his final moments, Dimple recognized his misplaced ambitions and expressed gratitude for Mob's friendship before dissipating. His consciousness merged with the broccoli, which became a city landmark. From this state, he continued watching over Mob and friends, fulfilling a symbolic protective role. His backstory held no human memories, recalling only existence as a spirit and former leadership of a spirit gang before Mogami nearly exorcised him. Dimple's appearance features distinctive red cheek marks visible on possessed hosts. His natural form resembles a wispy cloud or energy bulb with a detailed face, sometimes forming limbs. His abilities include possession, regeneration after near-total disintegration, hypnosis, energy projection like the Wraither Beam, flight, intangibility, and spiritual consumption. He could amplify power by absorbing external energy sources. In the Reigen spin-off manga, Dimple briefly possessed the esper Serizawa during an exorcism job, demonstrating his ongoing connection. His character arc concluded with a legacy of ambiguous guardianship, observing the world from within the broccoli while indirectly influencing events.
