Ada actually traveled back in time to the novel "Encounter" that she had read.
After learning the news, she cried and fainted all night (Ada, I was wrong, cried)
Before she could feel sad, Ada learned of her mission - to defeat the villain "Emil"
Ada: Is it too urgent to show it off now?
System: Want to be beautiful [Tsundere]
Intention: You are my only light in the darkness
