Luka Couffaine

"Music is often simpler than words."

- Luka

 is a character who appears in the second season of Miraculous: Tales of Ladybug & Cat Noir. He is Juleka Couffaine's older brother, and also a new student at Collège Françoise Dupont, who attracts the attention of Marinette Dupain-Cheng.

Physical appearance
Luka has aqua eyes, and brushed-back black hair that has been dyed teal blue at the tips.

Civilian attire
His attire includes a white shirt with a black Jagged Stone imprint, and black jeans ripped at the knee. He also wears a brown leather bracelet, two yellow and orange wristbands and his fingernails are painted black. He completes the outfit with a sky blue hooded jacket as well as red and black checkered sneakers. He wears a silver ring on his left pointer finger and black gauges.

Personality
Unlike his sister, Luka is a playful, charming and flirtatious boy. He can be socially awkward, so he feels that he "tends to make more sense with his guitar." He is also a very kind boy, especially towards Marinette in "Captain Hardrock", calling her "unbelievably brave." He is also skilled at reading people's emotions and expressing it through music with his guitar.

Marinette Dupain-Cheng
Marinette and Luka first meet in "Captain Hardrock". At first, Marinette is startled by him and stutters when she speaks to him. He teases her playfully about her stuttering but immediately regrets it when she frowns, embarrassed. She then begins to warm up to him as she listens to him play the guitar. He believes that music is often simpler than words. As a memento, he gives her a guitar pick of Jagged Stone, which she accepts, calling her a "funny girl." Alya Césaire notices Marinette's interest in Luka and teases her about it. Luka later compliments Marinette when he calls her "unbelievably brave" and Marinette, as Ladybug, blushes at his comment.
