The fourth battle of Wakayama Castle is between Ichinotani Tenma and Anayama Kosuke.  Anayama says "Justice" a lot.  He attacks Tenma with his warped sense of justice.  A badly wounded Tenma continues to fight, hoping for just one thing: to meet the father and mother he's never seen.
I never knew... 
I never knew such justice existed!
No sabía... ¡No sabía que 
existiera semejante "Justice"!
No lo sabía... ¡No sabía que 
existiera semejante "Justice"!
Eu nunca soube... 
Eu nunca soube que tal Justice existia!
