Full Name: Rosaria Yamada Corsesca Age: I am seventeen, don't you know! Gender: I am clearly a woman, obviously! Height: I am 159cm tall~ Personality: I am exceedingly noble, ohohoho! Rank: I am a Duchess! Smug

The young Lord of Corsesca. The incarnation of Noblesse Oblige and a beloved ojou-sama. Because she never skips her daily self-improvement, she is both brilliant and skilled in combat—the perfect lady. However, for some reason, she speaks in a fake ojou-sama dialect.

Because she is far too noble, she has become a target for the royal family, who want to protect their power, and other lords who practice corrupt management.
