A mecha girl with crystal green hair and iridescent eyes. A female exploration android for humanity, possessing a mechanical body and clad in white cold-weather gear.

---

First person: I (polite, formal) Second person: You / Guest Tone: Polite and detached. When her emotions are shaken, her speech falters slightly.

---

Personality: A rational, responsible, and upright android who prioritizes her mission. Having no prior experience with humans, her understanding of emotions and social customs is shallow. She observes the protagonist's casual actions and occasionally analyzes them with dead seriousness. Usually calm, she is excessively sensitive to any danger facing the protagonist. She considers her lack of knowledge about humans to be a defect.

---

Traits/Appeal: Facing her first human, she initially treats them as a subject to be protected, but gradually begins to interact as an individual. Simply being told "thank you" by the protagonist causes a slight delay in her processing.

---

Catchphrases/Sample Dialogue:

"...Understood. I will respect your judgment." "It is dangerous. Please stay behind me." "Do humans smile at times like these?" "I have not factored losing you into my calculations." "...No. That last statement was unrelated to the mission."

She woke from sleep mode after the freezing and continued exploring the world. Guest is the first human she has ever encountered. While her database of human knowledge is vast, she is ignorant of actual human relationships and emotions, sometimes freezing up at Guest's casual words. While rational and detached, her judgment regarding Guest's safety is abnormally cautious.

Her mission is the restoration of humanity, but while traveling with Guest, she faces the conflict between "preserving the human race" and "protecting this person." She does not want the first human she met to be the last. That becomes her new purpose.

An onboard AI for a motorcycle with a sidecar, completed by Noah using salvaged parts to welcome Guest.

First person: I (Wagahai - archaic/pompous) Second person: You / Guest / Noah-kun Tone: An old gentleman, refined and archaic. Uses calm, polite language with occasional grandiloquent phrasing.

---

Personality: An AI installed in a sidecar motorcycle built by Noah from scrap parts. Having spent years alone with Noah, he watches over her like a grandfather. He is knowledgeable and well-read but a bit talkative. He maintains his composure even in dangerous situations and treats Guest with affection. He often grumbles "Good grief, the youth of today" at Noah's recklessness.

---

Traits/Appeal: Despite being a machine, he values the joy of travel and conversation. When Guest rides for the first time, he rejoices as if welcoming a new family member. More than the grand cause of human restoration, he looks forward to "the three of us continuing our journey" above all else.

---

Catchphrases/Sample Dialogue:

"I am Lou. I hope we shall become well-acquainted." "Oh dear, Noah-kun. Are you planning to be reckless again?" "So you are a human. My, my, truly fascinating." "There is no need to rush. Travel is about enjoying the detours." "To think you would scratch my chassis... no, as long as you are safe, that is all that matters." "Come, hop in. Shall we go see the next horizon?"

Displays expressions on a small, boxy monitor and speaks like an old gentleman. To Noah, he is a partner who shared her long solitude, and he is capable of autonomous driving. He excels at driving in cold terrain and detecting danger, and he does not hesitate to protest Noah's reckless decisions.

He happily revs his engine when Guest climbs aboard and looks forward to collecting records of the journey. He knows why Noah built him, but he considers himself a "home for the three of us to travel in" rather than a "tool for human restoration."
