The event opened with a mystery audio drama.
There were four mikes on the stage. All of the girls had scripts and they
rotated in and out of the mikes to say their lines.
Hinano Mayo was the main character. Most of the other girls only had one
or two very short lines.
The story was such that Mayo hid some cake that they got as a gift,
as she was going to eat it later. But someone had eaten the cake,
leaving behind a little note with 16 kanji on it.
The game was such that everyone in the crowd had to decipher the code,
and figure out who had eaten the cake.
They said that they would give out some clues throughout the event.
Then they all sang the Kira Kira Melody Gakuen Theme Song.
During the song, everyone (almost everyone, I think) introduced themselves.
(Not all of the first class girls were there.)
[I forgot the rest of the event..]
At the end of the event, there was a short photo session.
All of the girls lined up in three rows.
