The 2.21 June software update for the current Taiko arcade is released today, starting with the public introduction of two IA songs which were previously featured as event-only songs for the NicoNico Super Conference 2 event. The first one is Enmei Chiryou (5/5/6/8), while the second one is Yobanashi Deceive (4/4/7/9). There is still no trace of that new, unknown IA song by Ishifuro announced weeks ago in a Taiko Team blog post.
