One of the most recent videos for The Great Ace Attorney had series creator Shu Takumi talking about the heroine, Susato Mikotoba. Details translated from the video are posted below (thanks Siliconera).
– Susato travels alongside Ryunosuke in his voyage to the United Kingdom
– Susato’s name was made from letters that Takumi felt were pretty, as he aligned them together
– She meets the requirements of being what’s called a “legal affairs girl”
– This is essentially a position that helps out attorneys
– Susato likes mystery novels, including stories with Sherlock Holmes
– She’s an informative lady since she’s big on reading
– Susato will often help out with useful information, and will occasionally say some strange but interesting quotes
– She also has a bit of a sweet tooth
– Susato’s design was made with a graceful Japanese woman as the main focus
– Seemed fitting to have her in a kimono given the time period
– Takumi had different kinds of ideas such as make her look like this, and have her holding this or that
– In the end, he decided that her looks would be best kept simple
– At times, she may seem more like an adult compared to Ryunosuke, but that is precisely what makes the two work well together as characters
