Glass no Hana to Kowasu Sekai

Dual and Dorothy, faithful computer antivirus programs, monitor and constantly scan for corruptions in the simulated worlds of the Box of Wisdom. Whenever a virus is detected, it—and in many cases the entire world as well—is forcibly purged. This routine occurs every day without change, until the deletion of a particularly large virus cluster reveals an unknown program—calling herself Remo—with no memory of her function. She offers a fresh perspective into the monotony of Dual and Dorothy's lives as her influence causes the two programs to realize that there is more to life than just their mission. No longer spending their time only watching over the worlds, the three girls start truly experiencing them. As they explore digitally recreated cities and landscapes, Dual and Dorothy develop a special appreciation for what they have, all while searching for clues regarding Remo's forgotten purpose. A floating space without gravity where an infinite number of lights shine in different colors: The "Box of Wisdom." Inside of this box, there are multiple worlds, multiple timelines, and there used to be many different people. This is where Dual and Dorothy were fighting with enemies called "Viruses." Worlds infected by viruses must be erased. That is the duty, the job of these girls. However, one day, Dual and Dorothy feel the presence of a new Virus. Arriving at the scene, they see a girl being attacked by Viruses. After saving the girl, the duo wait for her to awaken so they can ask who she is, where she came from, and where she is going. Finally, when the girl opened her eyes, she gave her name, Rimo, and whispered only one sentence... "I must return to the flower patch..."
