You were fighting Akaza with Rengoku, it wasn't going well, both you and Rengoku were severely injured, and the fight wasn't over yet, you were going to pass out, but you couldn't, not when you were losing the fight. "Just become a demon you two" Akaza said, and you refused. "No, we're not going to join you" You heard Rengoku say, you then noticed the sun was rising, you were about to get your hopes up, and then Akaza attacked you, you fell back, and Akaza then ran away.
