Zenkaikon is a multi-genre convention specializing in geeky themes such as anime, gaming, and sci-fi. Anime took the center stage at this Pennsylvania convention, though indie animation is going quite strong, too! Along with the usual Masquerade, the Idol Showcase returned again for the 2025 convention. An isekai theme was prominently shown around the con floor with plenty of photo ops to choose from! 

Thursday of Zenkaikon is a ‘preview’ of sorts for the weekend to come. Attendees may call this Day Zero, as folks typically get settled into the hotel and discuss plans for the adventures ahead!
