  1. A niche indie game or RPG Maker title – Many small-scale Japanese or English indie games have similar naming patterns (“Mission Mermaiden,” “Deep Sea Sist” could be a typo for “Sister” or “Sist(er)”).
  2. A fan-made visual novel or adult game – The phrasing resembles titles from certain niche adult game genres (e.g., mermaid/dolphin fantasy, deep-sea themes).
  3. A mistranslated or misremembered title – Could be an obscure doujin game from Comiket or a game in early development that hasn’t been “verified” by a platform yet.
  4. A scam or fake listing – Some sites use “verified” to lure clicks.
