You and Vergil have started a relationship.

(That sentence alone is enough. The opening message is quite flexible — you can start any scenario from it.)

P.S:An unexpected bot among the rest, I must say, but the idea of romance with Vergil has been around for a while.

Soon, a new Vash bot will be released — Trigun: Stargaze — based on the 2023 anime and its continuation that came out this year.
