Ayame Himuro (氷室 菖蒲, Himuro Ayame) is of the two main characters of all incarnations of Rikei ga Koi ni Ochita no de Shōmei Shite Mita. She is a 1st-year post-graduate science and technology researcher at Saitama University. Having fallen in love with her academic rival Yukimura Shinya, she embarks on a mathematical and logical journey with him to prove this love when he demands such proof. She can be snarky, but is usually serious and logical above all else, making her stick to her quest above all else.
Ayame has lavender long hair with light blue-green eyes. She wears a glasses and a lab coat with a official/business shirt and skirt with long stockings.
Similar to Shinya, Ayame has a serious look all the time and is extremely logical person. She loves doing mathematical and logical experiments and after confessing her feelings for Shinya, she started making experiments in order to scientifically prove her love. As she doesn't has a love experience, she can like Shinya, misunderstand situations and interpreted them in different scientifically way. Also due to her love inexperience, every time she is close to Shinya, thinks about him or even sees him, she can easily feel embarrassed and blush.
One day at the technology research department of Saitama University, Ayame confessed to her co-worker Yukimura Shinya. As Shinya had not experienced love, he wanted a definition of love and prove of how Ayame decided that she loved him. Since both loved they jobs, they agreed to make an experiment in which they will try to find proof if they love each other. They started collecting data and did a kabe-don experiment, to get data on the increased heart rate of Ayame. As the experiment wasn't enough to get full data and she started to get used to the situation, her heart rate started to get lower, so they tried increasing the heart rate of Shinya and Ayame tried to stimulate him with letting him touch her head. But then a co-worker Ibarada Ena brought to their attention that their experiment isn't correct and there are variety of reasons someone to get increased heart rate outside of the person being close to their loved one. They involved in the experiment Ena and Kanade Kotonoha, but concluded that his heart rate increased from all. Shinya then confessed, as he wasn't in much contact with other women, he gets nervous when is close to them, but Ayame was upset he got excited from all.
Later they did a cooking experiment, to see if you can implement love into cooking. As they were preparing the dish, Shinya was getting annoying the recipe wasn't numerically specific and had things like "a bit of salt". Ayame then explained him the two versions of implementing love into cooking, one that changes the taste and one that works visually for a psychological effect. Shinya didn't understand it and didn't believe that love will make the cooking taste better and wanted to even use a taste sensor to compare the data. But Ayame explained him that it will depend on the person and suggested she cook it and he experience both dishes. She calculated all the nutrition he would need and prepared a dish that would give him energy. She then served him two dishes, one presented with having his name written with a heart and he had to agree that one tasted better, even before tasting it. And she agreed as this was the way she infused "love" into the cooking.
