As noted on their Facebook Page:
“Despite Kyo being adamant about carrying out the ”TOUR2013 TABULA RASA -揚羽ノ羽ノ夢ハ蛹-” show scheduled on 24.05.2013 at Shibuya Public Hall, a special LIVE show for those who purchased the limited order only MINI ALBUM “THE UNRAVELING”, he has been hospitalized for further treatment and rest.
At this time, the show is scheduled to take place as planned, however, under unavoidable circumstances we will make an announcement over our official website.
We apologize for all inconveniences and worry we have caused all fans and affiliates and thank you for your continuous encouragement and support.
