Raynesia

Raynesia (called Lenessia in the anime) is a member of clan Corwen, the most prestigious clan in the East. She later becomes the Ambassadress of the League of Freedom Cities Eastal to the Round Table Alliance in Akihabara.

Female nobles don't have any real authority and instead exist for political marriages. This is the reason why she is so lazy and unmotivated, because she knows that she will never be in a position to do anything worthwhile and is expected to just look pretty and perfect

Appearance
Raynesia is well-known for her beauty, although that tends to irk her because she is aware of her position, which essentially required her to look pretty and nothing else. Her attire is left up to her personal maid, Elissa, while Raynesia herself prefers to wear comfortable pajamas.

Personality
Her personality is laid-back, gloomy, and lazy to the core. She would prefer to do nothing except eating, daydreaming, and napping for the entire day. She also dislikes taking showers. Nonetheless, being raised in a royal family, she knows how to act properly in society.

Whenever she daydreams in the public, due to her beauty, people misinterpret her behavior as being concerned about the future, and thus she has the nickname "cultured lady with a sense of sorrow." She only acts as herself in front of Krusty, who she realizes can see right through her facade. Thus, there's no point in putting on an act in front of him.

Given all of her shortcomings, she can be quite bold and straight to the point when a problem must be solved. For instance, when an army of 20,000 Goblins began invading cities, she voluntarily traveled to Akihabara to ask for aid from Adventurers while most nobles were still bickering among themselves about how best to exploit the Round Table Alliance to their advantage.

Palace of Eternal Ice arc
Raynesia and Elissa appear before Duke Sergead Corwen when the spies in Akiba return.

Libra Festival arc
Because she acted entirely on her own without the authority of the Nobles, she found herself forced to shoulder all responsibility, and had to go to Akihabara to become the Lander ambassador to the Adventurers. Ironically, Krusty tells her that since Adventurers don't care about politics, she gets to just laze around all day long, exactly what she wanted.

When she shortly realizes that she's now swamped with requests between the Guilds and Landers and now barely even has time for herself. She feels that she got conned by Krusty as a result.
