Well, it depends on the characters. Some might be amused, like Joseph Joestar. He might find the wild and creative interpretations in the fanfiction quite entertaining and laugh out loud at some of the over - the - top scenarios. Others, like Jotaro Kujo, might be a bit more critical. He'd probably analyze it closely, maybe even scoff at inaccuracies or out - of - character portrayals. And then there are those like Dio who would either be enraged if the fanfiction didn't show him in a 'glorious' enough light or be secretly pleased if it painted him as an even greater villain.
Sure, JoJo Part 7 manga is available in English. But the availability might vary depending on where you look. Some physical bookstores or online platforms might have it in stock.
