Description
Nenji Kashiwazaki, also known as Okina, is a former member of the Oniwabanshu, a group of shinobi who once served the shogunate. In the story, he runs the Aoiya, a restaurant and inn in Kyoto that also serves as the headquarters for the Oniwabanshu’s intelligence network. Despite his advanced age and seemingly easygoing demeanor, Kashiwazaki is a formidable fighter and a cunning strategist. He is widely regarded as the only person who could match the former Oniwabanshu leader in combat, wielding steel tonfa that can block sword strikes. When offered the position of leader, he declined, believing that the role should go to a younger person, and instead recommended Shinomori Aoshi. After retiring from active duty, Kashiwazaki settled in Kyoto and became a key information gatherer for the group.

Kashiwazaki’s personality often comes across as lighthearted and somewhat lecherous—he enjoys drinking games, teasing young women, and making inappropriate jokes. This outward behavior belies a sharp mind and deep loyalty. He is fiercely protective of those he considers family, especially Misao Makimachi, whom he raised alongside Aoshi. Misao looks up to him as a father figure, and he treats her with genuine warmth and care. His motivations are rooted in preserving the peace he has built in Kyoto and supporting those who fight for justice, including Kenshin Himura. When Kenshin arrives in Kyoto to confront Makoto Shishio, Kashiwazaki activates the old Oniwabanshu intelligence network to help locate Arai Seiku and Hiko Seijuro, offering crucial guidance.

In terms of development, Kashiwazaki experiences a shift from a retired, carefree innkeeper to a active supporter of the conflict against Shishio. Though he initially seems reluctant to engage in violence, he does not hesitate to fight when necessary, as seen when he briefly clashes with Aoshi. His abilities are not limited to combat; his knowledge of Kyoto’s hidden pathways and secret information networks makes him an invaluable ally. He is also a skilled guide and tactician. Throughout the Kyoto Disturbance arc, Kashiwazaki remains a steady, behind-the-scenes presence, using his experience and connections to aid Kenshin’s cause while maintaining his role as the jovial, if eccentric, patriarch of the Aoiya.
