Larue is a curse user who served as one of Suguru Geto's commanders, sharing Geto's ideology and viewing their group as family. He possesses a large, muscular build, light eyes, and mid-length blonde hair held down by a blue headband. His physical appearance prominently features two large hearts tattooed on his pectoral muscles. Larue typically wears only loose pants, preferring to remain shirtless and barefoot. He first appeared during Geto's meeting with his commanders and later infiltrated Jujutsu High alongside Geto and the Hasaba sisters. He remained present when Geto declared war on Jujutsu society. Following Geto's death, Larue distanced himself from other curse users, motivated solely by his desire to see Geto become king. He intervened in conflicts among Geto's followers, such as stopping a dispute between Nanako Hasaba and others, emphasizing that Geto would not want infighting within their "family." Larue declared no side was wrong and encouraged everyone to part ways, though he expressed hope for a future reunion. Later, Larue allied with Yuki Tsukumo. During the Shibuya Incident arc, he rescued Aoi Todo, Mai Zen'in, and Kasumi Miwa while Yuki confronted Kenjaku. In the lead-up to the Shinjuku Showdown, Larue met with Yuta Okkotsu and Miguel, proposing they fight Sukuna as a form of mourning for their fallen comrades. Miguel agreed under specific conditions. On December 24th, Larue joined the battle against Sukuna, rescuing Atsuya Kusakabe after Sukuna defeated him. Larue and Miguel engaged Sukuna directly. Larue employed his cursed technique "Heart Catch" to target Sukuna's heart. After Sukuna countered with a Black Flash, Miguel assisted Larue, who then activated "Cutie Honey" to force Sukuna's attention onto him. This distraction allowed Yuji Itadori to land a Black Flash on Sukuna. Larue and Miguel were later transported to safety during Sukuna's incomplete Malevolent Shrine. Following Sukuna's defeat, Larue and Miguel overheard Maki Zen'in criticizing Yuta for their delayed arrival. Larue's abilities include significant durability, demonstrated by surviving a Black Flash from Sukuna. His cursed technique, "Heart Catch," allows him to crush a target's heart remotely. He also uses "Cutie Honey" to compel a target's focus onto him. In popularity polls, Larue ranked 113th in the third poll with one vote and 66th in the fourth poll with 15 votes.
