Arisu ga Fushigi!

High school freshman Arisu endures a disastrous first day that coincides with her sixteenth birthday. Devastated by the experience, she returns home only to overhear a heated argument between her parents, leading to a shocking revelation: her mother is an angel and her father is a devil. They explain that despite their opposing natures, they fell in love and married, making Arisu a unique half-angel, half-demon hybrid. Because of her mixed heritage, Arisu struggles to control her supernatural abilities. Her mother informs her that finding her true love is the key to mastering her powers. While this connection is typically traced via red threads of fate, Arisu discovers that her threads have been severed. Left without this mystical guide, she must now rely on conventional methods to find her destined partner.
