Okina

 Kashiwazaki Nenji  is a strong fighter and a talented strategist. 
 
Okina was to become the next leader but refused the position, saying that it was the time for the young, not the old and recommended Aoshi to be the next leader.
 
 He was then made an agent in Kyoto for gathering information. Upon retiring, he gave up his fighting ways and now lives peacefully in Kyoto at the Aoi-Ya, in the headquarters of the Oniwabanshū which is now used as a hotel. It is here he raised Misao. 
 
Although old, Okina still possesses a quick mind and knows all of the outer and inner workings of Kyoto since the old intelligence network of the Oniwabanshū is still active. He uses this network to help Kenshin find Arai Seikū and Hiko Seijūrō. Okina tends to also like drinking games and pretty girls.  
 
When he refused to give Aoshi the information he sought about kenshin the two did battle and while they seemed evenly matched early on he was defeated and left in a coma. After he recovered he was present during the battle of  Aoi-Ya and was happy when kenshin returned with Aoshi.
