Become a Magical Girl and Create a Secret Society

As the New Year's bell rings in Tokyo in 2000, the ordinary female high school student Scarlet is involved in a mysterious whirlpool of fate. In order to save innocent lives, she signed a contract with a strange being and became a magical girl. From then on, Scarlet's life is no longer a peaceful daily life on campus, but a continuous battle with a witch who feeds on despair and pain in a "barrier" that ordinary people cannot see. Scarlet must join forces with other magical girls and travel through the shadows of the bustling city to fight hidden threats while also facing their own fears and loneliness. As she continues to fight, she gradually understands that this is not only a war about defeating the witch, but also a test of responsibility, strength and self-salvation. In Tokyo, where technology and unknown forces are intertwined, magical girls work hard to protect human society and try to find a way to survive amid ever-increasing external threats and internal conflicts. How will Scarlet shoulder this responsibility? Can she find a balance with light in the abyss of darkness?
