三角形の時間
This was the 5th live performance by Sankakkei no Jikan's acoustic unit, 'Majo to Inu' (currently in training). I think this every time, but Flan-san, who usually sings while playing the drums, has an overwhelming presence and skillful performance when singing with a piano or handheld microphone. On this day, they also premiered a new acoustic song, 'The Fools' Fair'. At first, I thought it was the reading part of 'The Shoeshing Boy Still Doesn't Know the World' (because the song was short). During the first one-man live, they did a paper-theater style performance with acoustic instruments, but it was 'Who's to Blame?'
