When is Kirino Kousaka's birthday?


I'm just curious because Ruri's birthday was mentioned. Kirino's birthday
might probably mentioned in some part of the light novel or manga.




Her birthday is April 8. It can be seen in this [birthday
plate](http://www.amiami.com/top/detail/detail?gcode=GOODS-00103195) that was
revealed during [Tsukasa Fushimi's 10th
anniversary](http://dengekibunko.jp/author/fushimitsukasa/) live streaming
[event](http://live.nicovideo.jp/gate/lv268871612).
