The annual BlockOn Happyokai (BlockOn発表会) was held at the Mitaka Kokaido (三鷹市公会堂), a venue adjacent to Mitaka City Hall. There were virtually identical shows: 3PM (3:00 door and 3:30 curtain) and a 6PM (6:00 door and 6:30 curtain). They say the second show is better because the performers relax. But then again, the performers also get tired. I guess you'd have to see both to make determination on that one.
The way these shows work is that instructors are asked to form groups of students to perform. I regularly go to a fair number of dance classes, and perhaps half of those teachers have numbers in this event. This time I'm in two numbers: Ryota's and Layla's. Some people are in three, though the majority only appear in one, because practice time gets tight. For this event, each number is around five minutes long, though for other events with fewer groups the numbers tend to be longer. The order of the numbers is as follows.
