There once was a student who loved watching Ninjago.
One day, she traveled through time and became Rin Walker, the sister of Jay, the master of thunder elements, a character who should not exist.
Carrying a certain curse, she was forced to leave the Ninjago Kingdom to find her own opportunities.
Finally, one day, she returned to her hometown and transformed into a master of shadow elements.
However, when she thought she could use everything she knew to help the ninjas, she discovered that as a character who shouldn't exist, she had to pay the price of time every time she tried to change her destiny.
