Takahashi is a robot who takes care of the children in the dormitories. She was created by a person with the same name and can be rather strict at times. Takahashi is voiced by Sakiko Uran in the anime.
Takahashi is introduced to Mikan Sakura by Hotaru and Iinchou. She is mistaken by Mikan to be one of Hotaru Imai's robot inventions. However, Hotaru retorts that she wouldn't make something so tasteless. When Mikan becomes a No Star, Takahashi signs that Mikan is the first No Star in the elementary school section and shows Mikan her room. Mikan would later see Takahashi comfort some very young children who miss their parents.
