A voice actor connection (Arisa Bunnings and Shana both being voiced by Kugimiya Rie (釘宮 理恵)). The name was given by one of the artists. Also a play on her name read as "Banningusu Arisa" (typical family name/given name order for japanese names.) Remove the extra 'n' the 'su' and elongate the a in 'Ba' and you have Baaningu (Burning) Arisa!
