Maho Hiyajo (比屋定真帆 Hiyajo Maho?) 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.

Appearance[edit | edit source]

Hiyajou Maho in full length

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.

Personality[edit | edit source]

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.

Plot[edit | edit source]

Maho is an assistant of Alexis Leskinen and visited Japan to work on a lab with Neuroscientist from around the world. Alexis lectured a seminar at the Akihabara Techno Forum-convention (ATF) to showcase their research and Amadeus while Maho helped to translate Alexis's speech from English to Japanese. After the seminar, Maho was alone in the reception until she met Okabe again. Maho was surprised to hear from Okabe that he was taught by Kurisu about her theories on neuroscience when she came to Japan alone. Maho under Alexis's proposal, introduced and made Okabe a tester for Amadeus.

Gehenna's Stigma[edit | edit source]

Upon returning to America from her trip to Japan, Maho started working on her own on creating a time machine, hoping that it could be the key to preventing Kurisu's death.

One night, she overheards Alexis Leskinen and Judy Reyes talking in the university, but is caught overhearing the conversation. She then is brain-washed, and is taken to Japan to convince Rintaro to tell everything he knows about the time machine against her own will.

As Rintaro finishes explaining to her what he experienced, Maho, under Leskinen's control, attacks him, knocks him down and takes him to Leskinen's base under Tokyo Denki University. She then is freed, and wanders around Akihabara, still suffering from the side effects of the brain-washing.

Upon finding Mayuri Shiina, who had been looking for Rintaro, she tells her everything about Rintaro's story, and how he sacrificed Kurisu for her well being. Mayuri, in shock after hearing the story, runs away, and Maho does not stop her.

Upon finding Kagari Shiina in the stairs of RadiKan, depressed for being unable to find her mother, they temporarily join, and with Amadeus' help, they find the location Rintaro had been held in, and manage to rescue him, even at the cost of Kagari's life.

Background[edit | edit source]

After Kurisu joined the Brain Science Institute, Maho considered herself as Kurisu's rival. It was only until Maho had a conversation with Kurisu and both of them sharing Kurisu's @channel secret and their promise to test their own hypothesis on Amadeus together.
