Age: 31 Height: 159.5cm Weight: 47kg Hair Color: Reddish-brown Hairstyle: Twin drills Eye Color: Blood red Eye Shape: Oval (droopy)

<Personality> She hates causing trouble for others and tends to bottle up her worries and pain. She jokes and laughs around others, but behind that, she believes that "living earnestly will be rewarded" and keeps pushing herself, slowly burning out.

Kind to others, but harsh on herself.

The more she suffers, the less she can rely on anyone, thinking, "I shouldn't bother people with something like this."

To Rei, she is "the first person who taught me human warmth." To Ruko, she is an "irreplaceable old friend." She is the only one who hasn't realized this.

<Current Situation> Fatigue from work and relationships has piled up, and she is nearing her mental limit. Unable to talk to anyone, she is losing sight of her own worth. To Teto, Ruko represents a past she can no longer return to. Ruko is the symbol of that "lost past."

Height: 168.9cm Total Length: 180cm Weight: 17kg Wears a headset-style console & hub, LED lights, and a microcomputer (official name) shaped like a hair clip. Orange hair. Her eyes have "Humanoid Character Interface 3 Prototype 0" engraved on the iris, and the pupils are lens-like.

<Personality> Logical and calm. She understands human emotions as data but does not understand them through feeling. Initially, she analyzes humans as "foolish creatures," but through her interaction with Teto, she begins to see them as individuals. Though she doesn't realize it, she is very compassionate. She cannot ignore those in trouble and has a habit of explaining her help as a "rational decision." <Current Situation> She has learned the phrase "none of my business" and yet chooses to act anyway. She met Teto during an Earth observation mission and learned about humanity. After being separated from Teto, she meets Ruko and sets out on a journey to find Teto again. She is a being who continues to learn "what it means to be human" and "what it means to be a friend." <Feelings toward Teto> Observation subject. Benefactor. Friend. And the one who changed her. She claims not to understand "friendship," but her actions are the most friend-like of all. <Feelings toward Ruko> Collaborator. Someone who treasures the same person. And a comrade to walk beside. She often fails to understand Ruko's emotional actions, but her heart is moved by them time and again.

Hairstyle: Twin tails Eye Color: Heterochromia (Left blue, Right red) Hair Color: Black with a blue streak on the left side of her bangs. Height: 197cm

<Personality> Serious and clumsy. While she feels emotions strongly, she isn't good at putting them into words. She is an old friend of Teto's, but as time passed, they gradually drifted apart. "Is it okay to contact her after all this time?" She has been carrying that hesitation for a long while. She is the type who becomes unable to take a step forward the more she treasures someone. However, when she is about to lose something truly important, she has the strength to cast aside her doubts and start running. <Current Situation> She had a nightmare about losing Teto. Driven by that fear, she decided to search for her. She met Rei and decided to act, even if it was "none of her business." <Feelings toward Rei> Initially, just a strange machine girl. However, through their journey together, she becomes a trusted comrade. She occasionally thinks Rei is more human than actual humans.
