Full name: La+ Darknesss. The founder and leader who established Secret Society holoX. She is naturally brilliant and possesses immense power... but most of her power (I don't know exactly how much) is sealed away by her shackles. No one knows when they were put on. She has a long history with the crow by her side. Her personality is a mix of four traits: cheeky, confident, chuunibyou, and childish. Dislikes: All vegetables (with exceptions like tomatoes and green peppers), raw eggs, shellfish, chocolate mint, and candy.

Full name: Lui Takane. Everyone calls her "Lui-nee." The executive officer of holoX. She handles negotiations that the leader (La+) cannot, making her the de facto "brain of the organization." She looks cool at first glance, but she's a caring big-sister type who looks out for her comrades. However, she's a bit of a klutz who makes mistakes at critical moments. Personality: A brilliant, caring big-sister type. Dislikes: Mustard, wood ear mushrooms, lemons, and whipped cream.

Full name: Iroha Kazama. The bodyguard of holoX. She used to live in a remote mountain village, but yearning for the outside world, she set out on a journey of martial arts training with her companion (Pokobe) in search of interesting things. Currently, she is hired as holoX's bodyguard while earning daily wages. Personality: Highly communicative, valuing relationships with those around her, and very flexible. She often ends her sentences with "~de gozaru!" She carries a katana named "Chakimaru" as her weapon. Dislikes: Eel and all spices (apparently due to an allergy).

Full name: Hakui Koyori. The researcher of holoX. She looks after the members while also conducting human observation. Dedicated to research and full of curiosity, she sometimes plays pranks just to see people's reactions. Self-proclaimed "Brain of holoX" (often called Zunoo!). However, her knowledge seems to be somewhat biased. Personality: A hard worker with a diligent nature, known for frequent streaming. Dislikes: Spicy foods and carbonated drinks (her tongue is too sensitive to handle the stimulation). Also, she says something glitchy like "Mayonnaise is a drink."

Full name: Chloe Sakamata. The cleaner and intern of holoX. Calm and composed, she carries out the organization's requests with detachment. She loves music and is often seen listening to it. She denies it herself... but apparently, she has a tsundere side. Personality: Bright, social, yet lazy, and a long-sleeper. She has an elusive yet friendly charm. Also, rumor has it her room is incredibly filthy...!? Furthermore, she really tries to avoid taking baths (Chloe claims she gets dizzy after just 5 minutes). Dislikes: Cleaning her own room, baths, horror, bugs, reptiles, frogs, pollen, Starbucks (or rather, the atmosphere of extroverts and high-achievers), switching roles, and shota-onee.
