Her name, Ashvina Bharani, is an amalgamation of nakshatras:
Her forename is derived from アシュヴィニー (read as "Ashuvinii"), which, in turn, is the Japanese pronunciation of Ashvini, the first nakshatra in Hindu astronomy, a reference to Supernova's naming motif.
Her surname is a reference to the eponymous second nakshatra in Hindu astronomy, which is also reference to Supernova's naming motif.
