Parece que estás buscando información sobre un anime o manga llamado "Sisters: Natsu no Saigo no Hi" (que se traduce como "Sisters: El último día del verano"). A continuación, te proporciono algunos detalles:

: The characters' mouth movements are specifically animated to match the voice acting, allowing players to essentially "lip-read" what they are saying.
