I'm not sure specifically which 'toki' you are referring to. There could be many things named toki. It could be a name in a fictional story, a brand, or something else. Without more context, it's hard to tell the origin story.
One possible interpretation could be that it has a mythical origin. If toki is a creature in a fantasy world, its origin story might be about it being born from magic or some other supernatural force.
Di Renjie was a TV drama, and Naru was a character in the drama. Na Lu was the princess of the Yue Kingdom, beautiful and infatuated. She lived in hatred all year round, but she also loved her lover, Yaka. In the end, she was killed by the Fake Loyalty Festival (Sar Khan) for killing the king's envoy and the two princes, Vita and Jongta. Before she died, she cut open her face and reminded Di Renjie and the others that the ruling loyalty beside Di Gong and the others was actually Shaer Han in disguise. The role of Na Lu was played by Li Xi 'er.
One interesting Naruto Toki Lemon fanfiction could be the one where Toki Lemon has unique adventures in the Naruto world. Maybe she teams up with Naruto to face a new and powerful enemy. Another could be about her learning special jutsus in the Hidden Leaf Village.
Nalu was a character in the TV series "Divine Judgment of Di Renjie", played by Li Xi 'er. She was the Yue Kingdom's Princess Consort, beautiful and infatuated. Nalu lived in hatred all year round, but she also loved her lover, Yaka. In the end, she was killed by the Fake Loyalty Festival (Sar Khan) for killing the king's envoy and the two princes, Vita and Jongta. Before she died, Na Lu cut open her face and reminded Di Renjie and the others that the ruling loyalty beside Di Gong and the others was actually Shaer Han in disguise. Li Xi 'er was playing Na Lu.
Another potential villain could be a character who was once a friend or ally of Toki but has been corrupted by the power of code - breaking. This character now wants to use their skills to gain absolute power and will do anything to achieve that, even if it means going against Toki and everything they stand for.
In 'code breaker toki fanfic', the world - building might be a great aspect. It could create a whole new universe where the code - breaking concept is integrated into every aspect of the story. For example, the society in the fanfic might be based on different levels of code - breaking abilities, and Toki might be trying to navigate through this complex world. This can add a lot of depth to the story.
