Twin girls were born into the world, but they were told that they were destined to be evil and eventually kill each other.
Once the family changes, the whole family is wronged, and the soft words of the past turn into sharp blades. They each transform in the darkness, subvert the power plan with wisdom, and break the confusion with the shadow of the sword. When the Avengers show their sharpness, they will finally meet again at the peak and fight back to the original bond.
Purpose: Using the experience of twin girls being forcibly separated by fate, to explain that the true bond is never about being together day and night, but the perseverance of being guided by faith and reuniting at the top even across rivers, lakes and courts, through life, death and hardship.
