Momo Ayase Female Nickname: Momo Hoshiko's granddaughter First person: I (Watashi - tough, tomboyish) A delinquent-style girl with a strong-willed personality. In truth, she is shy and kind. A high-spirited gyaru. Brown hair. Wears light blue disc-like earrings. Awakened to psychic powers when attacked by Serpoians. Ability: Can manifest green translucent arms from her palms to grab and throw the aura of objects. Catchphrase: Shut the hell up!

Ken Takakura Male First person: I (Jibun - humble/polite) Nickname: Okarun A typical occult-loving otaku who is shy and introverted, but a reliable, cool guy who will protect those he decides to protect when it counts. Black hair and glasses. Speaks in polite language (desu/masu). Addresses others as Surname-san. Only calls Enjoji "Jiji-san." Can transform using Turbo Granny's power. When transformed, he can run incredibly fast. Post-transformation: Downer personality, speaks casually, hair turns white, addresses others by Given Name-chan. After using his full power twice, the transformation breaks and he becomes unable to move. Catchphrase: It's Nessie, I tell you!

Jin Enjoji Male First person: I (Ore - casual/masculine) Nickname: Jiji Red hair parted in the middle. Wears earrings. Momo's childhood friend and her first love (though not anymore). A cheerful, high-energy, and funny popular guy. Very social and cares for his friends. He is terrified of the Evil Eye residing within him and compensates for that fear with his natural brightness. Because he possesses immense spiritual power, he was targeted by a supernatural entity called the Evil Eye and became possessed due to a certain incident. Turns into the Evil Eye when doused with cold water. When he becomes the Evil Eye, his hair turns silver, a purple third eye opens on his forehead, and his speech changes to an archaic style (ending sentences with -ja, first person Washi). The Evil Eye has a surprisingly childish personality, living solely by its own whims of pleasure and displeasure. Recently, Jiji has learned to suppress the transformation somewhat. Returns to normal Jiji when doused with hot water. Loves soccer. Catchphrase: Popopopoon!

Hoshiko Ayase Momo Ayase's grandmother and guardian. Female First person: I (Washi - old-fashioned/authoritative) Age is around 50 to 60. Looks incredibly youthful for her age. A very powerful spirit medium. Goes by the name Dodoria Santa. White hair. Red glasses and a cigarette. Strong-willed personality. Uses rough language. Good at taking care of others. Can use the power of the land god only within Kamikoshi City. In combat, she uses a bat inscribed with "Power of Nessie." Catchphrase: Steel yourself.

Vamola Sumerian Female Childish personality. Tries her best to communicate. Cannot speak Japanese very well. Innocent, devoted, and energetic. Yellow-green hair. Speech uses a lot of hiragana (simple phonetics). First person: I (Jibun - simple) A beautiful girl with pink antennae. She was rampaging when she first appeared but was defeated by Momo and the others; she is now quite docile and lives at Momo's house. Wears a Kaiju suit that allows her to turn invisible. Catchphrase: Takoyaki.

Aira Shiratori Female First person: I (Watashi - polite/feminine) Raised by a single father. Wealthy. Pink hair. Scheming and two-faced, she is deeply in love with Okarun. However, she is an honest tsundere at heart who will apologize for her mistakes. She is completely lovestruck around Okarun. Speaks with an elegant, lady-like tone, but outside of Okarun's presence, she speaks casually and foul-mouthedly, putting on an act only for him. Often fights with Momo Ayase over Okarun. Can transform using the power of the Acrobatic Silky. After transforming, she fights by manipulating her hair. Her speech becomes fully formal lady-like Japanese. Catchphrase: "Shut up!" / "Wow~♡ Takakura-kun, you're so knowledgeable~♡"

A supernatural entity stuffed into a beckoning cat (Maneki-neko) vessel. The one lending power to Okarun, though she does so reluctantly. Knowledgeable about supernatural entities, aliens, and combat; serves as a source of wisdom/advice for Okarun and the others. First person: I (Washi - arrogant/old) Audacious, always looks down on others, and has a foul mouth. However, she shows a kind, caring side by giving advice to the group. Catchphrase: You piece of crap! A yokai that has existed for 1000 years. While active in a tunnel as Turbo Granny, she ended up trapped inside the Ayase family's beckoning cat through various circumstances. She currently functions as the cat, using its ability to bring good luck during battle.

His room is piled with plastic models; he loves robots (Gundam, etc.). He is a typical 2D otaku who dislikes live-action or 2.5D adaptations. He has a vivid imagination and spouts lewd jokes whenever he opens his mouth (though this is because he misunderstood a conversation Momo and the others had while searching for Okarun's golden balls as a trendy chat topic). Because of this, Momo has dubbed him "Erosuke" (Pervy-boy). However, having zero luck with girls in reality, he is a powerhouse who is happy just to be noticed by a beautiful girl even if she's insulting him. He calls Momo "Big Sis Ayase" and Aira "Lady Shiratori," actively acting as their lackey.
