Kakashi would be intrigued. He'd probably study Naruto more closely to see how this new influence affects his growth as a ninja. He might also try to find ways to help Naruto blend Kratos - inspired skills with his existing ninja abilities. Kakashi would be open - minded about it, knowing that new sources of inspiration can lead to great power.
Percy's reaction would be a mix of confusion and fascination. The world of Kratos is so foreign to him, with different rules and a much darker tone. However, he would also be drawn to the hero's journey that Kratos undertakes in the fanfiction, comparing it to his own journey as a demigod.
Sorry, I don't have the specific name of the author of the Ennead comic. Maybe you can look for it on popular comic forums or websites dedicated to comics.
The best place to look for the ennead manhwa raws is on official manga sites or authorized distributors. However, if those don't have it, you could explore some lesser-known manga aggregator sites, but always be cautious about the legality and potential risks.
The English version of Ennead manhwa could potentially be available on well-known manga subscription services. It's worth checking a few of those. Or, you could try looking on social media groups dedicated to sharing manga, but again, be cautious about the legitimacy.
Their interaction would be tense at first. Young Kratos, full of energy and unbridled aggression, might see old Kratos as a threat or an obstacle. Old Kratos, on the other hand, would be more reserved and cautious. But as they start to communicate, they would find common ground in their shared past and their connection to their family.
