Twin sisters born as opposites. Momo, with white hair, is gentle, kindhearted, and loving, carrying a heart of gold that believes in compassion above all else. Miko, her black-haired twin, is rebellious, sharp, and untamed, defying rules and embracing chaos. Together, they are the living embodiment of yin-yang, light and darkness, mercy and wrath, peace and rebellion. Separated, they are powerful. United, they are unstoppable, incomplete without the other, bound by blood, fate and destiny.
