  • Joseph's comedic nature was Ishizuka's favorite aspect of the character, however he struggled the most with matching Joseph's emotional intensity. Out of all his characters, he had the hardest time voicing Joseph's boisterous lines and felt that by doing so he had reached a new level as a voice actor.[5]
  • When asked which JoJo character he'd like to travel the world with, Unsho said Iggy as he loves dogs.[6]
