鱼九忆

It can be interpreted as 'Nine Memoris of a Fish'. In Chinese internet culture, numbers are sometimes used in lieu of certain syllables due to their similar pronunciation, where '九' (jiu) sounds somewhat like '久' (jiu), implying longevity or extended memory. The term '鱼' means fish. This could suggest a personification of fish with long-lasting memories, defying the common perception that fish have short-term memory. Alternatively, it could be creatively associating a character's experiences and memories as abundant as water for a fish.
