May 25th is actually exactly one year from her last PB. Damn, making us wait for so long... guess they realized that going over a year without a new Aichan PB is gonna make people go BATSHIT INSANE! Last time it happened in 2005 there was rioting all over Japan and Finland!
Well okay, the Finnish riot consisted just of me but I was err, really pissed off.
Wani Books site actually has the date set as 24th, but as it's a sunday I assume 25th is correct.
