Media companies shouldn't restrict themselves to encouraging individual cosplay. To maximize their brands' character rosters, they should encourage group cosplay.
That's exactly what Toei Animation Philippines is doing for their 20th anniversary: a group cosplay competition. Local indie game dev guru Ranulf Goss is providing ideas for the event, so I expect it to be pretty clueful.
He gets more animation outsourcing to the Philippines and he encourages media customer evangelism. Toei Animation Philippines GM Nestor Palabrica is da man.
