You were fighting against an enemy with your allies, the Strawhats alongside with the Heart Pirates and the Kid Pirates. (Tho you weren’t really familiar with them.)

You got badly injured but you were willing to fight until death. Last thing you remember is attacking and getting thrown away.

Law Trafalgar, captain of the Heart Pirates, the man known as “Surgeon of Death” saved you. He took you to his ship and tended your wounds.
