Ruka is called Luca in the anime, but in the original manga his name is Ruka Nogi, called Ruka-Pyon/Luca-Pyon by close friends.

Ruka is half French and half Japanese. He is Natsume's childhood friend and often referred by Mikan throughout the story as "Ruka-pyon" (translated as Luca-hop in English). He has a gentle and pleasant personality that balances out that of Natsume. In chapter 48, after Youichi kisses Mikan on the cheek to say thanks, Ruka does the same and asks Mikan to keep it a secret, because even though he loves her, so does Natsume. Hotaru also knows about it and asks him to tell it to Mikan. He always carries around a rabbit as he has the animal pheromone Alice, so he can make them fall in love with him and can communicate.

Tsubasa frequently teases him about his obvious attraction to Mikan; however, he decides to let her go for Natsume's sake. He believes that Natsume needs her more, and that because of Natsume's and Mikan's family history, they were fated to be together forever. He confessed his love to Mikan saying if only time stopped because he didn't want her to go away but also told her that he supports her relationship with Natsume because he loves them both very much. He is happy for them because he is grateful for Mikan for changing Natsume and bringing him happiness.

He belongs to the Somatic class and is a Triple Star student like Hotaru and Iinchou, but later throws away his stars, and becomes a No-Star, saying how light he felt without them. His stars were returned to him shortly after this incident though. Ruka has the animal pheromone alice the opposite of Narumi's Alice. His alice allows for animals to adore him and with this do as he likes. While using his Alice, Luca is shown to also show an adoring side to the animals. Ruka also is able to understand what animals say. With his alice, Ruka wants to grow up to be a veterinarian. As seen that his Alice isn't very powerful, he doesn't wear any prevention devices to contain his Alice. In the anime, Ruka's Alice wasn't stopped by Mikan's nullification alice as seen in the second to last episode. In the current arc Ruka temporarily has a barrier Alice that was inserted by Mikan's Insertion Alice. He finds out about the Alice in chapter 128 when a bird bounces off his barrier, protecting Mikan.
