1) The Magic Music Club should be the abbreviation of "Magic City☆Music Fan Club".
It is a casual fair + free performance in the field of fandom that is purely about music..
Occasionally there are seats.--For example, Magic Sound 01. It is a small theater-style performance, so there are seats.
But in general, it should be purely live. (Live is generally No seats)
2) COS and sales will definitely be available.
3) It will probably end around 5 o'clock (according to convention, there is no detailed time listed on the official website)
4) Be sure to queue up. It should be faster if you have pre-sale tickets. Generally, you can enter smoothly if you arrive at the venue 2 hours before the opening (my own experience), but if you arrive at the opening or in the morning, it will be easier. If you arrive late, you may have to wait in line for a long time.
5) Not only is there no entry or exit, but it is also a two-day one-ticket system. That is to say, if you go on the first day, you can still get it on the second day. Get a ticket and go.
6) In fact, you can enter at any time, but you have to consider the queue problem. So the general principle of rushing to the venue is "get there early (the queue for pre-sale tickets will enter faster)" , or arrive late (it’s very fast to get in when the show is about to end. But the good books have already been snatched up. If you don’t go there to buy copies, it’s also good to go later)
