Luke is a playboy and, like the rest of the Notos Greyrat family, has a fetish for large boobs.

Although he plays around with most girls, he treats his liege, Ariel Anemoi Asura with utmost reverence, with her safety and well-being as his top priority.

Luke also treats Fitts as a colleague and friend instead of a girl to fool around with.

Tricked by Hitogami, he considered Rudeus as his enemy and lost reason. However, Ariel was, in the end, able to bring him back to his senses.

Luke was born into the Notos Greyrat family as an Asura Kingdom high noble. He was tasked at a very young age into the appointment of being the Guardian Knight of second princess Ariel Anemoi Asura alongside Derrick Redbat.

He was very fervent in his duties as a guardian despite his frivolous attitude to girls and his mediocre skills. He was so loyal that he sacrificed himself for his charge when they were attacked in the garden by a terminate boar. Sword-less, he tried to protect Ariel despite knowing that he could not win, even after he saw Derrick killed in front of him.

After being saved by Sylphy, who was teleported to them due to the metastasis event, he continued to guard Princess Ariel with Sylphy who was Silent-Fitts.
