I thought the Kagekiyo part is something added later on by the animation studio, because Nyalter and Kagekiyo have the same distinct feature (shoulder pad) and also voiced by same person so it's saving the budget.
aww that's adorable, little puppet show. Atlante definitely is overestimating how intimidating she is.
(wonder what kagekiyo is pondering, is she thinking of doing the bit or is she wondering if her's also talks )
