An employee at Aggle, the parent company of Enigma. She's Mai's emotional pillar and gives her great advice.

Unlike her sister Mai, she isn't a programmer—instead, she works in reception and accounting. She nearly died from an illness once, and her family has doted on her ever since. In order to gain independence from her overly attached sister, she started living alone... Those Toyama family dynamics are rather complex, aren't they?

Her mom, Phyllis, is a traveling painter, while her dad and sister both work for the same company. Though the family rarely gathers together, they seem to get along reasonably well.
