In the manga, Zero Two and Hiro have a different fate. They don't die. The plot takes them on a journey with various challenges but not to the point of death.
Zero Two is a very strong - willed and somewhat brash character, while Naruto is also determined but more open - minded. In a fanfic, when they first meet, there could be a bit of a power struggle as they both are used to being leaders in their own ways. However, as they face challenges together, like fighting off a group of powerful enemies that are a combination of rogue ninjas and klaxosaurs, they start to rely on each other. Naruto's optimism and belief in his friends starts to rub off on Zero Two, and she becomes more willing to trust others. And Zero Two's fierce loyalty and combat skills earn Naruto's respect, leading to a deep friendship between them.
