Hey. Well, If あなた go to muse.mu, click on the tour dates, click on the 日付 of when you're going, and usually it tells あなた when the tickets go on sale. Here's what it has for pre-sale.. Muse.mu pre-sale commences at 10:00 (local time) on Wednesday 9th December. ... Go on the internet site and it has a link so あなた can go to it. To bad it was already Dec. 9th, sorry! But, あなた might be able to still do it.
