While it’s not explicitly billed as a spooktacular event, the “This Is Halloween” framing of Anime Fusion—a nonprofit volunteer-run con that celebrates all things anime—suggests as much. “Whether you’re a newcomer to the genre, or a die-hard fan of the classics, Anime Fusion is the place to celebrate what you love!” organizers promise. The three-day blowout will feature cosplay contests, special guests, drag shows from House of Hades, cosplay-centric burlesque from Midnight Minxes, and performances from Japanese drumming crew Taiko Troupe. And, of course, there’s a vast and deep itinerary of geeky goings-on over the inclusively geared weekend, including board games, video games, boffer rooms, dancing, karaoke, and a whole lot more. $25-$60. Friday through Sunday. 3131 Campus Dr., Plymouth; find more info here.Through Sunday—Jay Boller
