لیوکای نوتوس گراییرات

Luke was born into the Notos Greyrat family as an Asura Kingdom high noble. He was tasked at a very young age of being the Guardian Knight to second princess Ariel Anemoi Asura alongside Derrick Redbat. He is very fervent in his duties as a guardian despite his frivolous attitude toward girls and his mediocre skills.

[Spoiler: Luke is indirectly responsible for curing Rudeus' erectile dysfunction by giving one of his aphrodisiacs to Sylphiette.]

[Spoiler: He was Hitogami's apostle in stopping Rudeus from supposedly using Ariel for his own personal gains. However, he was able to resist Hitogami's words in the end.]

[Spoiler: In the original timeline where Rudeus does not exist, he marries Eris and they become a happy couple together.]
