In June 2015, there was a campaign in Akihabara for the TV anime
Show By Rock.
At the Adores game center, the store side wall had pictures of
the main characters.
There was also a large banner for the Show By Rock smartphone game.
The wifi towers at the north side of Akihabara station
had advertisements for Show By Rock.
