On the 8th, TRIANGLE club Nishi-Shinsaibashi, Chuo-ku, Osaka featured an OTADAMA Otakusong Spirit concert featuring comedian/blogger/commentator and famous Asuka cosplayer Saki Inagaki doing some MCing and DJing, and, perhaps weirder and more awesome, the robot idols of nyoROBOtics performing a cover of "Shoot!," the theme to loli basketball anime Ro-Kyu-u!.
