Nekone (ネコネ) is Oshutoru's younger sister and the youngest candidate who passed the difficult court exam. She is a talented female who is qualified to earn a profession in philosophy but has been put on hold due to her young age.
Nekone is a young girl wearing a female uniform.
Having grown up without anyone to call friends, Nekone demonstrates a bossy attitude at first. She eventually starts to warm up to her brother's new companions, especially towards Kuon. She initially considered people to be selfish and that making friends with them will end up getting hurt. Her interactions with Haku are what eventually changed her outlook on the idea.
Ukon - Her old brother that she often bossed over despite having no visible effects on him. She cared deeply for him, over to the point of obsession as she worries so much for him, and was at a loss when she witnessed his passing first hand considering that her interference in his battle with Vurai costed him his life.
Haku - Nekone did not like Haku at first and could not comprehend why her brother would be interested in someone like him but as she began to understand more about him, she started to warm up to him. He became her only emotional support ever since he took up her brother's identity after Oshutoru's death. Over time they grow even closer to the point where Nekone considers him her real brother and saying Haku IS her dear brother that she loves so much and wishes to stay with, that it had nothing to do with him playing the role of Oshutoru.
Kuon - Nekone thought of Kuon to be unfathomable but eventually grew close to her, calling her sister.
Mikazuchi - It's unknown why but Nekone gets scared and angry at Mikazuchi whenever he is around. It's shown that her brother and Mikazuchi had always competed with one another.
- In the epilogue of Futari no Hakuoro, she finally managed to gain the title of scholar but she stayed in En'nakamui because she wanted to help her homeland as many refugees came fleeing from the destroyed capital of Yamato and from the long winter.
- She has a habit of saying "-nanodesu" at the end of each sentence.
