Shimazu Iehisa

The youngest of the Shimazu brothers, his speciality is tactics and strategy. Despite his young age and boyish looks, he is just as much of a perverted ladies' man as his older brothers are, and relies on his adorable looks to attract women.

While he is highly mature for his age, he is still a child and will complain when things don't go his way.

Like his brothers, he is madly in love with Kurohime, whom he refers to as "Kurohime nee-chan". However, unlike his brothers he is fine with her viewing him as a younger sibling as he enjoys having her bake cookies for him.

If recruited into Rance's army he will attempt to court both Ranmaru and Senhime, if Ranmaru is not cleared and Senhime is either not cleared or not in the roster, Ranmaru's troops will be merged with his, removing Ranmaru from the roster. The same does not happen for Senhime (if Senhime is cleared, she loves Rance more than Iehisa, if she's not cleared, they never talk).
