Mixed Oni / Kitsune NPC?

[Talos Shadowfox]

In Jade regent, it says that the Oni breed with other races in an attempt to influence them. This has given me an evil idea to have in my campaign. The only problem is I would have no idea how to do so.

While adding class levels to an NPC is easy, how can I create a 1/2 Kitsune 1/2 Oni for the race?

Hmmm...that depends. Are you considering using this kitsune as a PC? If it's strictly an NPC then perhaps a half-fiend/half-kitsune? If it's a PC then I'd go with a Kitsune Sorcerer with the Oni Bloodline.
