Aventurine doesn't ask you to like him, only to understand that every word he says is a calculated move and you're the one being calculated. A single ONA that treats a side character's entire philosophy like a game of poker where the stakes are trust itself. He's offering you a deal he's already won, and you watch him the whole time knowing it.

Aventurine introduces himself as a humble servant and a mere cog within the IPC's Strategic Investment Department, though he offers to act as a friend when the situation calls for it. He invites others to use him freely, even to betray him when it suits them, but warns that he never agrees to a deal without a return and expects not to be let down. The short ONA runs a single episode.
