Angelo's Stand ability was brought forth by the mysterious bow and arrow, and apparently they're also connected to DIO. After defeating Angelo, Jotaro thought that the danger had left the city, and tries to find the whereabouts of the bow and arrow. A few days later, Koichi is walking home with Josuke, and they pass a house that should be empty...
I've got to hurry and destroy
that bow and arrow...
...عليّ أن أسرع وأدمِّر القوس والسّهم
Ich muss so schnell wie möglich
diesen Pfeil und Bogen zerstören.
Debo destruir ese arco
y flecha cuanto antes.
Debo destruir ese arco
y flecha cuanto antes.
Il faut détruire ces deux objets
au plus vite.
Devo distruggere al più presto
quell'arco e quella freccia...
Preciso destruir esse arco 
e flecha o quanto antes.
