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.
