- Romaji: Akanesasu Shoujo
- Native: あかねさす少女
Always on the lookout for a big adventure in her small town, the bright and kind-hearted Asuka Tsuchimiya is ready to explore new things with her friends from the high school’s Crystal Radio Club. One day, out of curiosity, the group performs a ritual from an urban myth that claims to open a portal to another world. Much to their surprise, the near-impossible conditions for the ritual to work were met, and they find themselves transported to a new dimension enveloped by hues of warm gold and jet black. If that wasn’t enough, they encounter a different version of Asuka whose motives are a mystery.
