When I was in Tokyo with the family we went to a 'maid cafe' as part of the experience. It's one of the peculiarities of Japanese culture. The band sound great. They have some good rock bands over there that don't get much attention, although Babymetal have done well.
Your picture is great. You really capture that style.
Thank you very much :) We never got around to going to a maid cafe, but we did get to hear some of the music while visiting the shops, there's definitely a lot of interesting stuff to listen to and as you say, only very few of them are known in the rest of the world, which is kind of a shame
