"Kegareboshi 1" — based on the title alone — appears to be a Japanese-language media item (likely a film, short film, anime, or game trailer) whose name combines "kegare" (汚れ: stain/defilement/impurity) and "hoshi" (星: star) or possibly "boshi" as a phonetic rendering; together they suggest themes of taint, corruption, or a fallen/star-crossed motif. The "1" and "trailer" indicate this is the first preview for the work or the first episode in a series.
