When retrieving objects from across the air, others can lift a truck, but she can only turn over a coin;
Controlling thunder and lightning, others can cause a thunderstorm, but she can only charge the bracelet;

She is said to be a genius, but every ability is weak.
Could it be that her superpower is actually a trial outfit?
Mission: To move forward hand in hand and overcome difficulties together
