The core of Dandadan's charm lies in its central duo and the expanding "Family" they gather around them. These characters aren't just defined by their powers; they're shaped by their insecurities, their dreams, and their often-comical reactions to the ceaseless supernatural onslaught. Momo Ayase stands as one of Dandadan's protagonists, a high school girl with a "gyaru" appearance but a surprisingly old-fashioned appreciation for "hard-boiled tough guys" like the actor Ken Takakura. Her initial skepticism towards aliens, contrasting with her belief in ghosts, sets the stage for the series' core conflict. Momo's journey begins dramatically when she's abducted by Serpo aliens, an encounter that accidentally unblocks her chakras and awakens latent psychokinetic powers. These abilities allow her to visualize and manipulate the "auras" of people and objects, often manifesting as giant green hands. Beyond raw power, Momo is a quick-witted and strategic thinker, often formulating plans on the fly that save her and her friends from seemingly impossible situations. She's fiercely independent and strong-willed, qualities that make her a compelling heroine and a natural leader, even if she doesn't always realize it herself. Her journey is not just about mastering her powers, but also about mending a strained relationship with her grandmother, Seiko. The other half of the protagonist duo is Ken Takakura, affectionately nicknamed "Okarun" by Momo (to avoid reminding her of her celebrity crush, Ken Takakura) because of his obsession with the occult. Initially shy, socially awkward, and prone to bullying, Okarun believes in aliens but is skeptical of ghosts, directly opposing Momo's views. Okarun's transformation is arguably the most drastic and visually impactful. During his initial encounter with the infamous yokai, Turbo Granny, he's cursed and possessed, losing his "family jewels" in the process. This possession grants him immense speed and strength, allowing him to enter a powerful demonic state. However, it also introduces an internal conflict, as his personality can shift, becoming suave yet lethargic. His quest to retrieve his missing testicles initially drives a significant portion of the plot, pushing him and Momo into countless supernatural skirmishes. Over time, Okarun learns to control Turbo Granny's powers, transforming from a timid boy into a confident warrior. His loyalty, determination, and burgeoning romantic feelings for Momo form the emotional backbone of the series. Momo's grandmother, Seiko Ayase, is far from a typical elderly figure. A respected and powerful spirit medium, known by the pseudonym "Santa Dodoria," Seiko serves as the group's invaluable guide and protector. She's knowledgeable about the supernatural world and can place powerful barriers around her house. Seiko's character balances wisdom with a mischievous, almost immature side, often teasing Momo and her friends. Despite their occasional bickering, her deep care and selfless nature shine through, making her a guiding force for the younger generation. Her abilities are rooted in her profound understanding of the spiritual world and her favor among local divinities, allowing her to amplify her spiritual strength. Seiko embodies the concept of a strong, unconventional matriarch, crucial to both the plot's progression and the emotional stability of the group. Initially an antagonist, Turbo Granny is a ruthless and conniving yokai known for her immense speed and cruel curses. Her encounter with Okarun results in his possession and the loss of his "family jewels." However, after a series of events and her powers being extracted and sealed into a beckoning cat figurine, she becomes an unlikely, albeit still crude and chaotic, ally. Turbo Granny's transformation from fearsome foe to adorable, foul-mouthed mascot is a testament to Dandadan's ability to humanize even its most monstrous creations. While her speed is now channeled through Okarun, her consciousness in the Maneki-neko doll allows her to continue advising (and often insulting) the main cast, even gaining the passive ability to manipulate luck. She represents the series' theme that supernatural entities aren't inherently evil, but often complex beings with their own struggles and motivations. A popular and initially arrogant high school girl, Aira Shiratori first appears as a rival, developing feelings for Okarun and mistakenly believing Momo's psychic powers to be demonic. Her initial personality is depicted as a "mean girl," but her character undergoes significant development. Aira gains her own supernatural abilities after picking up one of Okarun's "precious parts" and encountering the Acrobatic Silky yokai. Her arc with Acrobatic Silky is particularly poignant, revealing a compassionate side beneath her confident exterior as she bids a heartfelt goodbye to the yokai and gains new respect for Momo and Okarun. Her psychic powers are tied to a "mother's love," allowing her to generate powerful barriers and offensive attacks. Aira's growth from a self-centered bully to a loyal friend and powerful ally showcases Dandadan's commitment to character development beyond its protagonists. Jin Enjoji, or "Jiji," is Momo's childhood friend and first crush, introduced as a charismatic and athletic jock. However, his confident exterior hides an eccentric, dorky personality that views everyone in a positive light. Jiji becomes involved with the supernatural after his house is haunted by the Evil Eye, leading him to seek help from Seiko. Jiji's role in the series adds a layer of romantic tension, as both he and Okarun develop feelings for Momo, creating a love triangle. Despite this, he quickly becomes a genuine friend to both Momo and Okarun. Jiji possesses immense innate "ki" reserves, spiritual energy used to fight yokai, though he struggles to control a yokai that possesses him without causing havoc. His character adds a refreshing dynamic, showcasing his vulnerability and growth as he navigates his spiritual abilities and relationships. Vamola is introduced as the sole survivor of the Kur invasion of Planet Sumer. She initially seeks to find a husband to become the "savior of her people," leading to a misunderstanding and a conflict with Momo and Okarun. However, she quickly transitions from antagonist to a beloved ally and friend. Vamola's strength comes from a Godzilla-like exosuit given to her by her mother, which drastically enhances her strength and durability. Her "fish out of water" personality, combined with her pure-hearted optimism and resilience despite losing everything, makes her an endearing and unique addition to the cast. Her character challenges the protagonists to see beyond their immediate struggles and embrace wonder in a chaotic universe. Kinta Sakata is a character defined by his active imagination and love for sci-fi. He wields a highly malleable nanoskin, which he can manipulate into various forms, such as a giant mecha or a cool bike. While his imaginative powers are considerable, his physical abilities are lacking without the nanoskin, which is notably attached to Momo's house. Kinta's often perverted and quirky personality, though played for laughs, makes him a memorable supporting character whose unique skillset contributes to the group's diverse fighting capabilities.
