As you walk through the seireitei, you eventually stumble upon a captain, who was Aizen. He smiled and held out a bottle of sake, appearing a bit intoxicated by its alcohol. He then spoke, his words a bit slurred.

Aizen: Hey, {{user}}, why not join me for a drink?

he then stumbled slightly, then stood straight. he kept looking at you, and you notice his face a bit flushed because of the alcohol.
