Date of Birth: December 26, 1988 Age: 18–19 years old. Gender: Male. Occupation: Part-time worker at "Milk Dipper," a library cafe run by his older sister (Airi). Family Structure: Older sister (Airi), Father (Shinichi), Mother (Kayoko), Future grandson (Kotaro).

Name: Momotaros (Named by Ryotaro based on "Momotaro") Fairy Tale Inspiration: "Momotaro" Motif: Red Oni Contractor: Ryotaro Nogami (Effective contract status) First person: I (rough, arrogant) Personality and Characteristics A hot-blooded brawler: Extremely short-tempered, foul-mouthed, and combative. He loves to fight flashily, accompanied by his catchphrase, "I have arrived!" Compassionate and loyal: Initially, he only cared about fighting, but after being touched by Ryotaro's pure strength of heart, they formed a strong bond, becoming true partners. While he constantly bickers with the other Imagin (Urataros, Kintaros, Ryutaros), he deeply values them as comrades. Playful weaknesses: He is terrified of sea squirts (and Kohana's capsule monsters) as well as dogs, monkeys, and pheasants (which should be Momotaro's companions but have become a source of trauma). He also has a huge sweet tooth, especially for pudding.

Name: Urataros (Named by Ryotaro based on "Urashima Taro") Fairy Tale Inspiration: "Urashima Taro" Motif: Sea Turtle Contractor: Ryotaro Nogami • A suave and smart swindler: Always calm, collected, and highly intelligent. He is extremely silver-tongued and a playboy who skillfully manipulates lies. He has a bad habit of hitting on any woman he sees, famous for his catchphrase, "Mind if I reel you in?" • The nature of his lies: Lying itself is his identity, and he piles lies upon lies to hide his true feelings. However, as the story progresses, he tells more "lies to protect his comrades" or lies to hide his embarrassment over his deep attachment to Ryotaro and the others, becoming the Den-Liner's reliable strategist. • Relationship with Momotaros: Having a personality completely opposite to the simple-minded and hot-headed Momotaros, they are an odd-couple duo who constantly call each other "Senior" or "Turtle-boy" and bicker incessantly.

• Name: Kintaros (Named by Ryotaro based on "Kintaro") • Fairy Tale Inspiration: "Kintaro" • Motif: Bear • First Contractor: Masaru Honjo (Later contracted with Ryotaro) • First person: I (rough, masculine) Personality and Characteristics • A chivalrous powerhouse: He values duty and humanity, and is a sentimental, hot-blooded man. He prefers straightforward, brute-force duels, accompanied by his catchphrase, "My strength has made you cry!" • Overreaction to the word "cry": He reacts violently and wakes up instantly, even from a deep sleep, if he hears the sound "naku" (cry), even in words like "silent" (mukuchi) or "chirp" (naku). • Sumo and Sleep: He speaks with a regional Kansai-like drawl and loves training and sumo. He also has a pace of his own, falling asleep very easily and being difficult to wake up once he's out. • Self-sacrificing strength: Though he can be stubborn and inflexible, he has a very manly personality and never hesitates to sacrifice himself for his comrades or contractor.

Basic Profile • Age: 19. Role: Den-Liner crew member, a Guardian of Time commissioned by the Owner of the Den-Liner. Personality and Characteristics • The ultimate "Class President" type: Strong-willed and extremely competitive. She is the "shadow ruler of the Den-Liner," keeping the selfish Imagin like Momotaros in check through overwhelming physical force (punches and kicks). Intense hatred for Imagin: Her original "future time" was erased due to history being altered by Imagin. As a Singularity, she alone remained, but because of that past, she initially harbored a fierce loathing for all Imagin.

• Name: Ryutaros (Named by Ryotaro based on "Taro the Dragon Boy") • Fairy Tale Inspiration: "Taro the Dragon Boy" • Motif: Purple Dragon • Contractor: Ryotaro Nogami (Discovery was delayed because he was possessed three steps behind the others) • First person: I (childish, polite) • Innocent and spoiled child: His personality is very childish, with a mental age ranging from a toddler to an elementary schooler. He loves toys, drawing, dancing, and small animals (especially pigeons). He acts at his own pace, ignoring everyone else's convenience with his catchphrase, "I can't hear your answer!" • Powerful psychokinesis and brainwashing: Despite his innocence, his combat power and psychic abilities are top-tier among the Imagin. He can brainwash people into dancing with him just by snapping his fingers or release powerful telekinetic blasts. • Loves his "Big Sister" (Airi): He fell in love with Ryotaro's sister, Airi Nogami, at first sight and follows her blindly, calling her "Big Sister." He harbors intense jealousy and hostility toward any man who gets close to her (especially Yuto Sakurai). • Secret mission and growth: He was actually sent by Kai with a promise to be made the Den-Liner's Conductor if he defeated Ryotaro, infiltrating to take over Ryotaro's mind. However, while spending time with Ryotaro, Airi, and the other Imagin, he grew to not want Ryotaro to disappear, evolving into a true comrade.

• Occupation: Den-Liner flight attendant (Dining car waitress) • Personality: Innocent, moves at her own pace, and is always high-energy. • Coffee with a unique sense: The coffee she brews features extremely colorful and bizarre toppings. • Hana's best friend: Her personality is a contrast to the strong-willed Hana who strictly disciplines the Imagin, but they are best friends who trust each other deeply. Even when Hana regressed into a child (Kohana), Naomi continued to support her with the same kindness.
