Maho Hiyajo is a member of the Brain Science Institute at Viktor Chondria University, one of the lead minds behind project Amadeus alongside Alexis Leskinen and Kurisu Makise's senior and friend. While Maho's field of study is neuroscience, she specializes in artificial intelligence. Maho is one of the main characters of Steins;Gate 0. A feisty young woman. Due to her extremely short stature, she is often mistaken for a child despite being in her twenties. She has long dark-green hair, and mostly wears casual clothes and mismatched shoes. Despite being a genius, and Dr. Leskinen's right hand, Maho started developing self-trust issues after Kurisu Makise appeared at the university, often considering herself the Salieri to Kurisu's Amadeus. After Kurisu's death in Japan, Maho started to talk to Kurisu Amadeus more often forming a relationship like a mother and child until she met Okabe and had to stop interacting with her. She is aware but is often annoyed every time other people mistake her as a child, unaware of her true age and occupation.
