Second, one of the guitarists for the Matina ALL STARS (魔帝那オールスターズ) session band has been announced: Ryuto (龍兎) [ex-Saruin, lolita23q (少女-ロリヰタ-23区), the LOTUS]. There's not really a Matina connection, except that lolita23q did a photobook with KISAKI once... I guess. The second guitarist is still TBA.
Finally... new music will be released at the event!!
There's not much information yet―presumably it will be a CD by MIRAGE, but even that's not specified by the text―except that the new music release will be live-limited. Hopefully it will pop up for purchase afterward!
