Sergay Wáng

Sergay a commander in the Artai military who serves as Nagis righthand man is Ninas adoptive father and also serves as part of the council of Garderobe representing Nagi. His character design is similar to Yuuichi Tates from MyHiME however Sergay is voiced by Katsuyuki Konishi while Yuuichi was voiced by Tomokazu Seki and every other Otome character with a HiME counterpart is voiced by the person who did their HiME counterpart so he may or may not actually be Yuuichis Otome counterpart.
