Because Princess Marianne's Geass qualification is low, she can't meet the requirements of C.C. to fulfill C.C.' s wishes and the emperor's ideals. Therefore, Lu He has been experimenting and coding with mice since he was born. Li Nana's ability in the distribution of invisible neurons is much higher than that of her brother Lu Luxiu, and Princess Mariana even intends to let the two brothers and sisters grow up and combine to give birth to offspring with higher Geass qualification. This is because both Li Nana and Lu Luxiu got eggs from Mariana, but some factors of the eggs they got were different. Li Nana has a genetic factor of C.C., and has obtained a C- sensitive factor, which can be combined with other people's spirits. In other words, you can send information directly to other people's minds for spiritual communication. This invisible neuron has no direct causal relationship with Geass and Code, but directly affects the innate sixth sense of human beings. For example, as a certain ability, or as a sequela of the experiment, at most, you can make spiritual contact with others after awakening. Princess Marian also cruelly planned to destroy Li Nana's senses to exercise her Gus ability.

However, Li Nana's ability now is that her eyesight, pretending to be destroyed by the Geass imposed by the emperor, began to unconsciously exercise her senses other than the five senses.

Finally, the official novel revealed that at Lu's request, Li Nana learned to control himself from C.C. through Suzaku.
