I almost hope she's taking a break - she needs a rest if she's going to be doing another grueling tour not only in Japan but other Asian cities/countries (isn't she going to Korea this time?). It may not seem like much compared to the Japan tour but having to travel, prepare yourself for a show, and adapt to the new arena(s) isn't easy. Hell, going to a totally different country is hard enough regardless if you're there to perform or have fun D:
anyway, yeah... I'm sorry to anyone that's going this year who will miss out on Ayu
