When the sky falls, the author always finds a way to turn things around.
Meet Chen Lexue, a fragile modern college student. She accidentally stumbled into a high-level game and was overwhelmed by the shock. Her main body is fine, but her little soul has to follow the System, completing missions in a state of constant terror while still managing to enjoy a pretty decent life. She has no idea that she and the System have blundered into another high-level game.
The perks provided by the System are tied to tokusatsu-style masked heroes. She can transform into a female rider, and she also gets special skill cards. They'll keep her alive.
