An early news leak by otakumu.jp announced that the next Magical Mirai concert event for 2015 will (reportedly) take place at Nippon Budokan in Tokyo at the Science and Technology exhibition area. The event is planned to span 3 days, between September 4th and 6th.
This news comes before Crypton Future Media’s own announcement stream scheduled for tomorrow (March 9th), so take this news leak with a slight grain of salt until official announcements are made. Crypton Future Media’s stream is scheduled to start tomorrow night at 7:00 PM JST. Stream link: http://live.nicovideo.jp/watch/lv212902774
