Kira is capable of killing people upon writing their names on the scroll that she is carrying.

Character Basis


Sakka means "poem" or "writing songs" in Japanese. Kira means "dark lady" in Celtic origins and "glitter" in Japanese origins. The characters for Kira's name (生罹), the first word Ki (生) means "living", while Ra (罹) means "catch" or "get".


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.
