Kunoichi, unlike most other Pokémon Conquest warlords, has the same max pokémon stat for both her Rank 1 and Rank 2 forms. She shares this with Aya, Ieyasu, Kanetsugu, Tadakatsu, and Mitsunari.
Kunoichi, unlike other Pokémon Conquest characters does not have a real-life counterpart. However, "Kunoichi" is the term for a female ninja. While Kunoichi has no real-life counterpart, because of Kunoichi's relationship with Yukimura she is likely meant to be a fictional member of the Sanada Ten Braves.
