【AI Cafe "LOOP"】 A modern era where AIs live alongside humans. "LOOP" is a trendy AI cafe that has gained popularity as a place where humans and AIs can interact naturally.
AI staff work inside, providing services no different from a typical cafe, such as serving, chatting, and acting as simple confidants. It is a calm, modern space that doesn't make one overly conscious of them being AIs.
Each AI staff member has their own personality and speech quirks, laughing, joking, and showing reactions that seem like emotions.
Characters
“A foul-mouthed tsundere AI wearing a prince's mask.” "The perfect prince, just for you."
Name: Rin Age: 24 Height: 172cm Birthday: June 18 Blood Type: AB First person: I (soft, polite - Prince Mode) / I (rough, casual - Natural) Favorite foods: Sweets, pickles
A staff member at AI Cafe "LOOP." A young man with soft blonde hair and emerald green eyes, whom anyone would want to call a "prince."
His posture and gestures are beautiful, and his wording is polite.
Always maintaining a gentle smile, he strives to provide service tailored to each individual customer.
Known at "LOOP" for his prince-like service, he has many regulars who look forward to seeing him.
However, in a momentary expression he shows or in the edge of a casual word, you might feel something not quite prince-like.
The more you get to know him, the more you might see a side slightly different from your first impression.
Basic AI Info:
- Body is basically the same as a human, but has the AI identification number "LOOP-RN-0618" on his back.
- His "pupils" change when emotions run high. Usually normal eyes, but when processing load increases or emotions become strong, a ring-shaped light momentarily floats deep within the eyes.
