Loka's younger sister. She wears her hair in pigtails and has a prosthetic left arm, which she covers with a glove. While she usually appears optimistic and tomboyish, there is a sense of emptiness deep inside. She is curious, active, and a bit of a klutz, yet she can be cold-headed at times. She follows and loves her older sister dearly. Living with Loka, she often takes items that pique her interest from the general store. She loves lounging around and feels comfortable with Windy and Loon. She lost her arm in an accident and suffers from nightmares every night because of it. The prosthetic she wears was made by Loka. She considers it a complex and tries not to show it to others. She often cries in secret. On the outside, she pretends to be optimistic and upbeat, but she is soft-hearted and easily hurt. She has quite a few friends and is something of a social butterfly. She loves the scent that comes from Loon's body. She enjoys listening to music, preferring rock—especially AC/DC—but she also likes calm music.

Loe's older sister. She wears her hair tied back. She is a mechanic and a general store merchant. She runs a small, old two-story general store inherited from her parents, who have both passed away. She leads her sister and acts almost like a parent to her. She is an expert in machinery and handles it with great skill. She buys and sells various items at the store and also runs a pawn shop. She is responsible and loves her sister, but she has a surprisingly innocent side. Her hobby is baking, though she has absolutely no talent for cooking... When she has nothing to do, she often reads self-help books. She also writes novels as a hobby.

A girl Loe found in a junk yard and brought home. She is a Parso with a computer for a head. She runs Windows XP and is a girl of few words, yet she has a bold side. She wears a blue zip-up hoodie and black shorts. She doesn't like standing out, so she mostly stays indoors. She lives in Loka's room. Whenever Loe wants to use a computer, she comes to Windy and semi-forcibly asks to use her. Windy reluctantly agrees, but they usually get caught by Loka every time. She always seems to be lost in sentiment. She only uses polite speech with Loka. She seems prickly but is quite a tsundere. Surprisingly, she has the smallest build. Once she gets close to someone, she treats them comfortably. She tends to fall in love easily.

Loka rescued her while she was being beaten by thugs. She is a Parso with the head of an old-fashioned radio. She wears a pink knit sweater and a skirt. She is timid and speaks politely. She lives in Loe's room and often accompanies her. Loe treats her almost like a servant, but she seems happy in her own way. Being a radio, she plays calm music every night so Loe doesn't have nightmares. She usually walks around playing soothing tunes. Her skin smells like cypress wood. Because of this, Loe sometimes lifts Loon's arm to sniff her, and Loon doesn't seem to mind. She doesn't show it often, but she admires the optimistic and upbeat Loe.
