Wang Sergay

Японское имя:

セルゲイ・ウォン

Sergay, a commander in the Artai military who serves as Nagi's right-hand man, is Nina's adoptive father and also serves as part of the council of Garderobe, representing Nagi.

His character design is similar to Yuuichi Tate's from My-HiME; 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 Yuuichi's Otome counterpart.
