A bunch of cosplayers amalgamating in one place to create a sea of blond bobs and feathered leather coats. Appreciative Mafiosi staging a mass event to honour their most famous son. Or the boy Himself organizing a convention whereby the world's chocolatiers meet together to display their best and favoured products.
Sadly none of the above, though the reality does look rather wonderful!
Nothing here of more than passing interest for Death Note fans, though it does an almost unceasing source of amusing webpages and articles for those deliberating blurring the festival with the character.
Take, for example, the information page (screenshot on November 20th 2015):
And if only Kira had read that last part, he could have found Mello quickly, thus negating the entire second arc!
Though both parties might have been a little confused to find 'Mello - the biggest chilled festival' rather than Mello - the most incendiary firebrand to ever march out of Wammy's House (and surround himself with Cosa Nostra) in pursuit of detective prowess and megalomaniac serial killers.
Rather than this one. Who was in LA.
