Perhaps she tells fairy tales with magical creatures like unicorns and fairies. These tales could be about love and kindness, teaching important moral lessons.
Well, it depends on her skills and the passion she puts into it. If she is truly passionate about the stories she tells, she will pour her heart into it. She may use different voices for different characters, describe the settings in great detail, and build a connection with her audience. This would make her a very good storyteller. But if she lacks practice or enthusiasm, the stories might not be as well - told.
Naruto himself could be an interesting pairing with Lady Death. His positive and determined nature could contrast well with her more somber and death - related aspects. Another could be Sasuke. His dark past and brooding personality might have an interesting interaction with Lady Death. And Kakashi could also be a good choice. His experience and calm demeanor might make for an engaging relationship with Lady Death as they face various challenges in the Naruto universe.
Lady Death Lemon could be an original character created for this fanfiction. She might be a powerful being with a connection to death or the afterlife in some way, perhaps having powers related to life - force or the passage of souls, which would be really interesting in the context of the Harry Potter universe.
Generally speaking, you won't find nudity in Lady Death comics. The comic's appeal lies in its plot and artistic style rather than resorting to nudity for effect.
One idea could be that Lady Death, being a powerful entity from another realm, senses Naruto's strong will and unique chakra. She decides to visit the Naruto universe to observe him closely. Naruto, initially confused by her presence, soon realizes she has knowledge that could help him become even stronger. They form an unlikely alliance where Naruto learns new skills from Lady Death, which he then uses to protect his village in a new and unexpected way.
