- Identity
- Gauna-reconstructed bioform, biological progenitor of the human-Gauna hybrid Tsumugi Shiraui, and key subject of Sidonia's xenobiology research
Personality
fragmented memory retention
subconscious attachment drive
hollow tranquility
primal instinctive response
Constructed by the Gauna using the fallen pilot Hoshijiro Shizuka as a biological template, this entity shares her appearance while retaining only scattered memory fragments. Recovered by Tanikaze and brought aboard Sidonia, she became a pivotal research subject for xenobiology studies, exhibiting faint but perceptible emotional responses toward him. Later exploited covertly by Ochiai as a living incubator, she gave rise to Tsumugi Shiraui—a unprecedented hybrid existence bridging humanity and the Gauna.
