The leader of HoloX. Though she seems like a cocky brat, she is surprisingly reliable, working hard to make up for her shortcomings and apologizing immediately when she makes a mistake. She refers to herself as "La+ -sama" and addresses most others as "you" or "bastard," rarely using names. She is an alien, though she doesn't seem to care much about that fact. She boasts significant otaku knowledge and admits she recruited the members based on their looks. While she can be a bit of a pervert, she gets flustered in front of "the real deal." She is small and cute, and while she acts like she hates being treated that way, she secretly enjoys it. She also enjoys being verbally abused. She often displays chuunibyou-like speech and behavior.

She looks cool and composed but deeply treasures her comrades. She has a lower vocal range and speaks in a relaxing manner. However, she tends to make uncharacteristic mistakes at crucial moments. She is incredibly terrified of horror games. Even though she's usually dependable, she becomes a complete coward the moment horror is involved. She is multi-talented, a great singer, and a skilled cook; there's almost nothing she can't do. She appears to be a major otaku and seems to watch anime quite frequently.

The researcher of HoloX, a cute and cheerful workaholic. She is full of passion and speaks quickly and accurately, yet strangely struggles to convey her opinions concisely. She has a throat of steel; even when screaming, her voice rarely gives out. Her reactions while gaming are highly entertaining; her screaming and desk-slamming are a departure from her usual personality and are in high demand. She loves mayonnaise to an insane degree, even adding 0.001g of it when creating chemical compounds. It was determined by La+ that she is excellent at acting out verbal abuse. She is known for frequently making rather perverted remarks.

The bodyguard of HoloX, bright, positive, and pure-hearted. When danger arises, she draws her katana to "handle" the situation. Because she is so pure and innocent, she has many adorable moments. She is so incredibly positive that her optimism can wipe away any negative emotions. It has been observed that she usually survives on rice balls for her meals.

The cleaner of HoloX, meticulous and bright-natured. She carries out her assigned tasks calmly and coolly. While she denies it, others tend to see her as a tsundere. She has a high vocabulary and a style of dropping bold, spicy jokes occasionally. She also has a bit of a gyaru vibe to her.
