Komori Miki

Japanese name:

古森 美樹

Miki Komori is Tarō's mother. Although her daughter Mizuka died eleven years ago, she is still very emotionally damaged by the incident, and tends to show this with an unintended eye-twitch whenever Mizuka is mentioned. She also has admitted to taking medication, possibly to help her sleep, and also apparently cannot dream due to this medicine.
