Nekohana was a samurai in service to Lord Nerai. His appearance was that of an anthropomorphic cat.
When Lord Nerai was ordered to commit seppuku by Lord Hikiji, he wrote a confession detailing his involvement in the attempts upon the life of Lord Noriyuki of the Geishu Clan. Lord Nerai gave this letter to Nekohana to take to the Shogun, as it would implicate Lord Hikiji as the mastermind behind the assassination attempts. However, Nekohana was intercepted by the Neko Ninja and slain. With his last action, he gave the confession to the ronin Miyamoto Usagi, before perishing.
