Right after the yesterday's broadcast on NicoNico Douga for the EVER song, a japanese message was advertising you that the purchases of the online broadcast tickets are now open. Because yes, it seems that the YFC concert in germany will be broadcasted on NicoNico Douga for those who have purchased an online ticket. A ticket can be buyed for 3000 points (1 point = 1 Yen) and will let you watch the broadcast. When you're trying to purchase a ticket and if you don't have enough points on your NicoNico Douga account, a red text will redirect you on a page where a big yellow button are and who will let you buy the number of points you need ! ^_^ You need a credit card for this, they accept foreign cards !
I've managed to get my ticket for the broadcast. And because my credit wasn't working (for an unknown reason), my french friend Leo have kindly helped me with her credit card, thanks to her ! <3
And if someone is interested to see the official page for all the details (in Japanese) and also the links for the page of the broadcast, and many other things, click on the banner, you will be redirected into the NicoNico Douga webpage with all of this ! ^_^
