>>2930997I will quote the wiki on this one: "If one takes apart Rena's real name (Reina), "Rei" would mean 0 and "Na" (from "Nana") would mean 7, possibly referencing the author's name, Ryukishi07. That strengthens the theory that Rena being intentionally made by 07th Expansion the signature character of the series. This intentional translation was also responsible for something called "Rena Day," specifically July 7th, 2007 (07/07/07), where 4chan's anime boards and Japanese image threads were flooded with massive Rena picture spam.
