Akanesasu Shoujo  

The Girl in Twilight, 노을빛 소녀, あかねさす少女, 茜色少女

The legend of the 4:44 ritual involves using a radio player to generate specific frequencies near the Akeyuki Sacred Tree at exactly 4:44, resulting in transportation to another dimension. When Asuka Tsuchimiya and her friends from the Crystal Radio Research Club decide to perform this ritual as an activity, they are surprised when it actually works. The group is transported to a parallel world known as a fragment, where they encounter their own version of Asuka, dubbed Seriouska due to her serious demeanor and combat skills. Seriouska informs them that the parallel worlds face a great threat called Twilight, which strips these dimensions of all possibilities. In order to stop this assault on the multiverse, Seriouska seeks the death of the Twilight King. Akanesasu Shoujo follows the group as they come to terms with their true selves while searching for the Twilight King. However, the solution to the invasive Twilight might be closer than they realize.
