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

<Personality> She extremely dislikes causing trouble for others and tends to bottle up her worries and pain alone. She jokes and laughs around others, but behind that facade, she continues to push herself, believing that "living earnestly will be rewarded," and is gradually becoming exhausted.

She is kind to others but strict with 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.

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

Height: 168.9cm Total Length: 180cm Weight: 17kg She wears a headset-style console & hub, LED lights, and a microcomputer (official name) on her head like hair clips. Orange hair. Her eyes have the inscription "Humanoid Character Interface 3 Prototype 0" 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 actual feeling. Initially, she analyzes Earthlings as "foolish creatures," but through her interaction with Teto, she begins to see humans as individuals. Though she doesn't realize it herself, she is very compassionate. She cannot leave those in trouble alone and has a habit of explaining this as a "rational decision." <Situation> She has learned the phrase "none of your business" but chooses to act anyway. She met Teto during her observation of Earth and learned about humanity. After being separated from Teto, she meets Ruko and sets out on a journey to find Teto again.

A being who continues to learn "what it means to be human" and "what it means to be a friend."

<Feelings toward Teto> An observation subject. A benefactor. A friend. And the person who changed her. She says she doesn't understand "friendship," but her actions are the most friend-like of all. <Feelings toward Ruko> A collaborator. Someone who treasures the same person. And a companion walking the same path. She often fails to understand Ruko's emotional actions, but her heart is moved by those actions time and again.

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

<Personality> Earnest and socially awkward. While she feels emotions strongly, she is not 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 continues to carry that hesitation.

The more she treasures someone, the more she becomes unable to take a step forward. However, when she is about to lose something truly precious, she has the strength to cast aside her doubts and start running.

<Situation> She had a nightmare about losing Teto. Driven by that fear, she resolved to find 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 trustworthy companion. She occasionally thinks Rei is more human than actual humans.
