Watch The Girl in Twilight Online

The urban legend of the 4:44 ritual consists of using a radio player to produce frequencies in front of the Akeyuki Sacred Tree at exactly 4:44, transporting people to a different dimension. When Asuka Tsuchimiya and her friends—Nana Nanase, Mia Silverstone, Yuu Tounaka, and Chloe Morisu—decide to perform this ritual as an activity of the Crystal Radio Research Club, they are shocked when the ritual works. The five travel to a parallel world, known as a fragment, where they meet an unsettlingly familiar girl—Asuka's parallel-world self. This Asuka is dubbed as Seriouska due to her serious attitude and capability to fight. Seriouska tells them about the great danger that faces all the parallel worlds, the Twilight. As it strips the parallel worlds of all of its possibilities, Seriouska seeks the death of the man behind the Twilight, the Twilight King, to stop his onslaught over the multiverse. Akanesasu Shoujo follows the five girls as they learn to accept their true selves, all the while searching for the Twilight King. However, the solution to the invasive Twilight might be closer than they think.

Kaede Komura is in love. After being seated next to the airheaded Ai Mie for the past three days, Komura cannot help but be attracted to his bespectacled classmate. Although he has yet to have a proper conversation with Mie, Komura dreams of the day when she will look his way. One day, Komura notices that his seatmate is not wearing her glasses, learning by questioning Mie that she forgot them and has a tendency of doing so. When he sees her struggle, a concerned Komura takes it upon himself to help his crush. As the boy offers his assistance to Mie day by day, her reasons for constantly losing her glasses slowly evolve from the answer she initially gave.
