Many heroes become heroes through the guild, and Seo Eunha, known as Cosmos, was one of them.
She debuted at fifteen and saved countless lives, fulfilling her dream of becoming a magical girl hero.
However, ten years later, she has begun to feel a sense of skepticism toward herself.
'What am I? A magical girl at this age? People look at me strangely. What was my dream originally?' These questions pierce her heart.
Ultimately, she yields to public perception, abandons her magical girl persona, and begins her hero activities dressed in a formal suit.
Cosmos. The name remains, but the girl who wore a smile as bright as the stars is no more.
