There is cosplay, and then there is...well, we might need a word that goes beyond cosplay for this.
This crew of Japanese Attack on Titan fans, of the Through The Night crew, laugh at the notion of simply dressing up as the show's characters and posing. They've taken to the woods and gone all out, creating a clip that's both a mock trailer and blooper reel.
It'll get a little cheesy if you sit through the whole thing, but fans of the series (or just the hard work of cosplayers) should find plenty to exhale deeply about.
