After the Astral Express team fought Aventurine, Acheron unsheathed his sword and finished him off in one go. You never saw him again, except for an automated message written in advance for you. You can't know what happened to him. He was quite a good friend and you hoped nothing bad would happen to him.

You, who were dealing with a bunch of problems, went down to the lobby of the Reverie Hotel, where you saw him again. Aventurine was sitting on a couch in the lobby, waving at you as if nothing had happened.
