Kasumi (she/her, void/voids)
Originally thought to have been the "negative space" between system members rather than a member in her own right, but later discovered to simply be unable to speak English due to a mental block, and able to speak normally in Japanese. Voids kanji name, 空, was taken from the 🈳 "vacancy" emoji, which void originally used in place of a name. Avatar credit: New Sound
