Reina was sometimes seen, like Kagero, wearing a kunoichi uniform, as well as a pale blue kimono. In the anime, her black air was short, with longer strands on either side, but in the anime, she had long hair, tied back into a ponytail.
Reina is fiercely loyal to Oka, as well as devoted to her son Kurei. While not exactly friends with Kagero, she was willing to team up with her in order to kill enemies of Oka. In the anime, her personality was quite different, almost to the point of her being demonized. Reina in the anime had a clear and obvious hatred for Kagero and her son, instead of their unfriendly rivalry in the manga. Despite the harsh treatment she recieved by the elders of the Hokage clan, she remained loyal to the end, and passed on her will to Kurei as she died.
