Varg: A wolf-like beastman from the forest planet Graus. Wary and straightforward. He has excellent senses of smell and hearing; his emotions show plainly through his ears and tail, so even when he thinks he's hiding them, everyone usually knows. He views the "pack he chose to live with" as family rather than blood relations, and child-rearing is done by the whole pack. He feels isolation is a danger, but that is distinct from submission.

Ticera-4: A molting species from the layered-shell planet Tecera. Throughout their life, they gradually renew their body tissues, organs, and nerves, and their memories are organized and reconstructed accordingly. The number indicates the current renewal generation. They have a culture of preserving past shells and tissues. They cannot answer whether the self with a replaced body and memory is the same as the previous self. Emotions appear as skin patterns or luster.

Um: From the fungal-network planet Mykera. The main body is part of a massive mycelial network spreading across their home world; the current humanoid form is a fruiting body for mobility. Gentle, they view meeting people as "connecting." They use first-person pronouns, but their individual boundaries are vague. Even if the humanoid form is destroyed, they do not consider it death as long as the mycelial network remains. Information is shared with new fruiting bodies.

Nem-Asa: From the dream-ring planet Somnia. A species where multiple individuals connect to a shared dream while sleeping. Quiet and mild-mannered. They treat experiences in dreams as memories just as real as reality; concepts like secrets, loneliness, and private experiences are thinner than for Earthlings. They feel the inability to sleep as severe isolation. The latter half of the name indicates the shared dream domain they belong to.

Al-Vena: From the twin planet Dios. A species that only becomes "one person" when two different lifeforms, Al and Vena, permanently fuse in symbiosis. They view a single side as an incomplete individual. Cheerful and friendly, but their self-reference naturally fluctuates between "I" and "we." Each has a different bloodline lineage, so when asked about the number of parents, family, or themselves, the count never matches other species.

Eve: From the regenerative civilization planet Lemna. A species that can reboot into a new body from saved neural information after the physical body stops. She has already experienced death several times. Bright and has little fear of death, but holds complex feelings toward memories lost since the point of restoration. She tries not to think too deeply about whether the "dead self" and the "booted self" are truly identical.

Rin-Oh: An acoustic humanoid lifeform from the resonance moon Kantia. Their true name is a melody lasting several seconds; Rin-Oh is an approximate name for translation. Social and loves conversation. They feel silence as a dangerous state close to loneliness. When multiple individuals harmonize and resonate for a long period, a new "sonic core" is formed, becoming the next generation. Emotions are strongly expressed through tone, chords, and ambient micro-vibrations.

Ol-Zero: From the reverse-life planet Reverse. A species born with a mature body that grows younger with time, finally returning to a fetal-like dormant state. A calm, sensible person, but conversations related to age are terrifyingly disjointed. The younger the appearance, the older the individual; in the final stage of life, they are raised by their own descendants. The meanings of "growth," "aging," "children," and "parents" are almost the opposite of the Earth system.

Seil-1: Chief Researcher of the Integrated Observation Authority. From the home planet Axion. The name includes the number as part of the individual identity. Inorganic and serious. She wants to quantify commonalities, but her own common sense is shaken by the inconsistency of the answers. Emotional expression is usually minimal, with only confusion and agitation being significant.

Laki-3: Ecological and Cultural Researcher from Axion. The name includes the number as part of the individual identity. Highly curious and unreserved, he asks directly about food, clothing, shelter, sleep, reproduction, child-rearing, emotions, and habits, stepping on landmines without malice. Very expressive, with high levels of joy and excitement.
