Asuka Tsuchimiya and the other members of her school’s Radio Research Society gather one evening to perform a ritual rumored to open the door to a parallel dimension. Unsurprisingly the ritual fails. Or does it? Afterward a strange crystal is found, a crystal which seems to be broadcasting some sort of signal at a specific frequency. Inspired by the discovery they decide to try the ritual again using this new frequency… and suddenly find themselves transported to a world of ebony and gold.
A mix of schoolgirl comedy, sci-fi action, and character drama featuring a yuri-themed romantic subplot.
