Kaya posted on his blog that he will be part of an unique event to kinda go hand in hand with his theme of Blue Rose Excursion. This time its called 青い薔薇の秘密 (aoi bara no himitsu) or Secret of the Blue Rose. The event will be on September 26th at Salon Papageno. From the pictures on their site, the location seems like a cozy little lounge. Its pretty cool!
The flyer for the event is really pretty!
