Luke Notos Greyrat

Luke Notos Greyrat is a supporting character in Mushoku Tensei: Jobless Reincarnation. He is Rudeus Greyrat's cousin, belonging to the Notos branch of the prestigious Greyrat noble family in the Asura Kingdom.

Luke serves as the dedicated guardian knight to the second princess Ariel Anemoi Asura, prioritizing her safety and well-being above all else. He works alongside the court mage (initially known as Fitz/Sylphiette).

In terms of appearance, he's described as tall, well-built, and very handsome, with brown hair styled combed back.

Personality-wise, Luke is a classic playboy and womanizer—sharing the Notos Greyrat family's infamous traits, including a particular interest in women with large breasts. Despite his frivolous and flirtatious side with most girls, he is extremely serious, loyal, and fervent in his knightly duties toward Ariel, even if his actual swordsmanship skills are considered mediocre compared to top-tier fighters.

He appears mainly in the later arcs (prominently in Season 2 of the anime), often involved in the political intrigue surrounding Ariel's path to the throne.
