Was back from London this morning and slept a good portion of the day away to rest up. I have to say with it being my first Miku concert ever I was pleasantly surprised with how relatively well it went. There was a few hiccups which I feel could have been solved with more staffing but I feel it could have went well. Also getting into the venue at like 4:30/5pm and having to stand until 7pm after there being barely any seating besides the floor since 11am, aha. The VIP mixups as well with rando standards getting the bands and messing up those sections.
The concert was absolutely magical, and the JP fans in VIP leading the callouts and such was great to really get everyone into it. I even saw one JP fan leap about 2ft in the air during "Remote Controller", that was some energy.
The worst was probably hearing about some terrible people who were picking on other fans just because they got better spots or being rude to them because they were from abroad, but I hope those kind of people never come back. But I've heard those who were victims have been given a lot of fan support worldwide and weren't deterred from coming back, which is great.
Oh, and regarding merch I was pretty fast into the line (it was only about two lengths of the queue barriers in) and stickers were already gone. I've heard they'll hopefully be selling stickers online so I hope so since they were gone like lightning. That was the only merch I wanted that I couldn't get. I'd like a replacement poster too, they weren't wrapped very tightly or inside cardboard carriers or anything, and easily got crushed/bent so my poster doesn't look the best right now. Print quality isn't the best so I'm not sure I'll regularly use my merch (bag or jacket) for anything besides display until another concert comes up. It's all super cute though.
