Alisa Haiba, elder sister to Lev Haiba, inherits a striking blend of Japanese and Russian heritage, marked by long sandy blonde waves, vivid green eyes, and a statuesque 178.5 cm frame. Known for her modeling career after high school, her beauty parallels a personality brimming with warmth and exuberance. She frequently supports Lev in volleyball, though his on-court blunders prompt her to apologize to spectators with a mix of sisterly loyalty and mild embarrassment. Their bond shines through her affectionate use of “Lyovochka,” a Russian diminutive for Lev, and her efforts to grasp volleyball basics—a task aided by Akane Yamamoto’s patient explanations. During pivotal matches, like Nekoma’s clashes with Fukurōdani and Nohebi, her cheers pivot to flustered face-hiding or polite bows when Lev falters. Her presence spans the Spring High Preliminaries and Tokyo Nationals, where she humorously misinterprets Akane’s admiration for Lev as romantic, envisioning future kinship. Post-timeskip, she and Lev grace a Shibuya perfume billboard, modeling side by side. Documented trivia notes her April 5 birthday, fondness for sea urchin sushi, and playful anxiety over Lev’s popularity. Polished mannerisms, like covering her mouth when startled, mirror her upbringing, while Russian terms and her mixed roots subtly color her speech and appearance. Official media, including *LAND VS. AIR*, maintains her role as Lev’s steadfast, unchanging supporter.
