The 'Stranger in a Strange Land' trope also works well. Suppose the male reader is from a different village or even a different world. A Naruto female, say Hinata, might be the first to reach out and befriend him. This trope allows for a lot of exploration of the Naruto world from an outsider's perspective while also developing a relationship between the two characters.
Another common trope is the 'Rescue Mission'. If a Naruto female gets captured, the male reader steps in to save her. This not only showcases the male reader's bravery but also gives an opportunity for the female character to be in a vulnerable state, leading to a stronger emotional connection between them after the rescue.

Another trope is the 'damsel in distress' where the reader gets into some sort of trouble and Damon has to come to the rescue. But sometimes this trope can be flipped, and the reader ends up saving Damon instead, which is an interesting twist.
