i watched like half on nichijou but i couldn't get fully invested in it because it kinda requires that you are familiar with japanese culture, so i just didn't understand a lot of the references.
it's the curse of becoming a side character
jotaro has it too because he heard screaming and just went "nah it's nothing" which makes no sense lol
i feel like that was more comedic relief than anything because they were literally right around the corner from the very loud fighting
