Kira seems to be based on Sakuya Izayoi, from the Touhou Project. Both are the third playable character in their respective series and wear similar clothes. Also, Kira being a hidden killer is based on a popular fanon theory of Sakuya being a killer because of the names for her spellcards.

Also, her names and spellcards are a shout-out to Light Yagami from the manga Death Note.
