This was a live broadcast of the Bang Dream stage at the Tokyo Game Show.
The hosts were Itou Miku and Toyota Moe, and the guests were
Yoshida Yuuri and Tadokoro Azusa.
This was a live version of the monthly Hello Happy Circle Housoukyku
broadcast.
They played the new Hello Happy World song "Yappy School Carnival",
for the first time at this event.
This song will be released in the game later today.
The seiyuu said that they all sang in this song.
Then they played a few games of the Girls Band Party game.
Miku and Yuuri played first, then Moe and Azusa, and all four
seiyuu played together at the end.
Then a kigurumi of Michelle (the bear character) came onto the stage.
