I live in Ontario, but we're considering making the trip to Otakon next year. If we do, I'll be bringing about 5 Umineko cosplayers, I don't know who exactly we'll go as, but by the end of August I'll have an arsenal of Umineko cosplays at my disposal xD So we can pretty well fill in the gaps.
We might do the witches
Beato, Virgilia, Eva-Beatrice, witch Maria and new girl? There's a possibility of a 6th person coming so maybe we'd get Lambda too.
