— the lore of K-Pop group LOONA. It is incredibly nuanced, but there are some main general plot points. The 12 girls exist on three different planes: LOOΠΔ 1/3 on Earth, ODD EYE CIRCLE on Middle Earth, and YYXY on Eden. Their worlds exist on a möbius strip, but there are multiple theories concerning how. One is the mirror theory, which is strongly supported by the girls' representative colors. Another is that the strip is actually the LOONAVERSE timeline, with LOONA stuck in an infinite loop.
