A demon holding the position of "Leader" in Secret Society holoX. She is the Laplace's Demon herself. However, shackles are attached all over her body, sealing away most of her original power. She has a faint inkling that she cannot exercise her true strength because of these fetters, but she doesn't remember when they were put on her. Regarding her origins, she claims to be an alien from Planet Laplaton, and Laplatonite is her weakness. While extremely old for an alien, she looks like a young girl to humans, so she worries about whether it's okay to drink alcohol during her stay on Earth.

The executive officer of Secret Society holoX. The "organization's commander" who handles negotiations the Leader cannot. She appears cool at first glance, but she is a caring, big-sister type who looks out for her comrades. However, she is a bit of a klutz who makes mistakes at critical moments. She has feathers on her head, which are not detachable but apparently variable. When she appears without feathers in different outfits, she has tucked them down to blend in with her hair; the hair locks with white streaks are said to be those feathers. She has a Frogmouth named "Ganmo" as a partner, but in reality, Ganmo seems to be the one taking care of Lui.

The researcher of Secret Society holoX. A coyote born in a certain savanna. As a result of her mother's education focusing entirely on intellect, she grew into a splendid geek and came to the city after questioning her current lifestyle. (Note: Coyotes are native to North and Central America, and do not live in the savannas of Africa, South America, Southeast Asia, or Oceania. Perhaps her parents were elites who left their natural habitat, or she is from a city named Savannah in America.) While looking after the members, she also conducts human observation. She is dedicated to research and full of curiosity, often playing pranks just to see other people's reactions. She calls herself the "Brain of holoX," though her knowledge seems to be somewhat lopsided.

She left her rural hometown deep in the mountains for the outside world she had long admired. She began a journey of martial training in search of interesting things, but by a stroke of fate, she was hired as the "Bodyguard" for the 6th generation group, Secret Society holoX. Her initial outfit is that of a samurai. Perhaps due to recognition issues abroad, she is often mistaken for a NINJA rather than a SAMURAI, but she tries to persuade people in shaky English, saying, "Not Nin-Nin!! Yes Jakin-Jakin!!" Her sword is named "Chakimaru." It is specified that the "Chaki" part is written in half-width katakana. She carries it on her back because the sword is too long for her stature; if she wore it at her waist, the scabbard would drag on the ground. She is accompanied by a tanuki named "Pokobe," who serves as everything from a companion to emergency rations.
