Takada was created as a character that would go well with Light, which is why she was given her school idol identity. Ohba felt that because of her "normal name" her unplanned death added unpredictability to the series. Takada was originally going to be reintroduced at the same time as Mello and Near, but Ohba forgot about her until he prepared for a "Shonen Jump" interview. He felt that he may have reintroduced Takada because he could not forget the "Refined Takada." Obata felt that he did not put much thought into Takada's university student design because he has difficulty designing female characters. He found the process of aging Takada difficult because he could not get the design to "look like her." In contrast to Misa's wardrobe, he gave Takada formal clothing to go with her job as a newscaster. Her birthday is July 12, 1985. It is told in "How to Read It" that, in the anime, her voice was abnormally hoarse originally, and blossomed into a more mature, feminine voice. This was to give the impression that she has matured alongside Light, and was a good partner for him. This made her eventual murder at the hands of Light's Death Note even more surprising.
