One common theme is friendship. Ushio and Tora have a very special bond, and many fanfictions explore how this friendship grows and endures through different situations. Another theme is adventure. They often go on various quests in the original work, and fanfictions expand on these adventures.
One great ushio x tora fanfiction is 'The Bond Beyond Worlds'. It beautifully explores their relationship in a world where they have to face new and unexpected challenges together. The way the author describes their interactions is really engaging.
We should avoid focusing on the 'lemon' aspect as it may involve improper content. For regular Kancolle - Ushio fanfics, one characteristic could be the blending of different story elements. Kancolle has its own lore with shipgirls, and when Ushio is introduced, the fanfic might explore how his character meshes with this world. It could also play with different genres, such as adventure or mystery, while still staying true to the core identities of the characters from both the Kancolle and Ushio concepts.
The relationship could develop through shared experiences. For instance, Naruto and Tora could get lost in a mysterious part of the village that is filled with ancient ninja traps. As they work together to escape, they learn about each other's strengths and weaknesses. Tora might be small but is very agile, and Naruto has his brute strength and ninja skills. By relying on each other, their relationship becomes stronger and more meaningful.
If brought back by a necromancer, Tora could be more intelligent and have a deeper understanding of the ninja world. Since it has experienced death and resurrection, it might have insights into the spiritual side of things that normal cats don't. Tora could also be more aggressive in protecting the necromancer, seeing them as its savior. And perhaps it would have a new form of communication, not just the normal cat meows, but something more complex that can convey more detailed information to the necromancer.
Sasuke would probably be indifferent at first. He is more focused on his own goals of getting stronger. But if Tora somehow gets involved in a situation that affects Sasuke's plans or if Tora shows some useful skills, he might start to respect Naruto's decision to keep Tora. For example, if Tora helps them track an enemy ninja.
One common theme is friendship. Harry and Tora's relationship is often at the center, showing how they support and care for each other through different trials.
Overcoming differences is also prevalent. Given that they might be different in character or origin in the fanfiction universe, they often have to work through their differences to achieve a common goal, like saving their world or helping a friend in need.
