This was a live broadcast of a press conference.
The emcee was an announcer, and he said the room was packed with press.
The announcement was a for a new anime song streaming service,
where they had 50000 anime related songs for a fee of 600 yen per month.
They invited five seiyuu guests for a short talk and photo session.
The guests were Suzuki Minori (Walkure), Suwa Nanaka (Aqours),
Mimori Suzuko, Yoshioka Mayu (Wake Up Girls), and Komagata Yuri.
After a short talk with the seiyuu, they brought out an iphone
and had Suzuko try out the new app.
For a few minutes, they showed the screen while Suzuko was doing
searches and looking at the songs available.
Then they talked about playlists, and they had all of the seiyuu
make a playlist.
The lists were already made, and they showed each seiyuu's lists on a
big board. Each seiyuu then talked about the songs they chose.
After the seiyuu talk session (total around 20 minutes),
there was a photo session of the seiyuu.
The seiyuu all stood, and had their photos taken for a few minutes.
Then they brought out chairs for the seiyuu to sit in.
The presidents of the various music companies came out,
and stood behind the seiyuu for another set of photos.
After a few minutes the seiyuu left, and the remaining 20 minutes
were talk by the guys.
