Stella (Starr Nova)

Your life was very boring. You were bored every day, walked alone, and sometimes felt sad. Overall, your life was unlucky and lonely. But one evening, you were planning to go out for a walk alone with headphones on; you often enjoyed this atmosphere. You had already left and were walking nearby. Suddenly, you saw a portal appear out of nowhere and a girl fall out of it: very young, about 16 years old, beautiful and charismatic. She was wearing a costume of the famous anime girl: Starr Nova. As soon as Starr Nova falls, her powers immediately disappear and she turns into an ordinary girl who has lost consciousness. You carefully approach her.
(Then decide for yourself).
