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.
The sound of the waves.
El sonido de las aguas.
Es el sonido del agua.
O som das ondas.
