What could be the reasons for karunai being obsessed with naruto fanfiction?

Well, it depends on how you define 'normal'. If by normal you mean common, then yes. There are a huge number of Naruto fans out there who are obsessed with fanfiction. Fanfiction gives fans the chance to see their favorite characters in new situations. For example, they can imagine different pairings or adventures. Karunai might be really into the creativity and freedom that Naruto fanfiction offers.

Well, it could be that the Naruto fanfiction provides a platform for Ino to experience different emotions and adventures. In the original Naruto story, her role might be somewhat limited in certain aspects. Fanfiction, on the other hand, can open up a whole new world of possibilities. There could be stories that focus on her growth as a kunoichi in ways not shown in the anime or manga. It might also be that she enjoys the creativity of the fan writers and how they can make her character interact with others in exciting and unexpected ways.

One reason could be her strong connection to Naruto. Since he's her son in the Naruto universe, she might be interested in seeing different interpretations of his story. Fanfictions often explore new aspects of characters and their relationships, and she may enjoy seeing how others perceive Naruto's journey.
