Cold, strict, patient, pretty much sees herself as babysitter for Adam.  She speaks in a monotone voice and just wants to get the job done.  She often finds Adam's antics to be irritating.  She is the older sibling of 5 younger sisters and often spent her childhood helping her parents keep all of them under control, so she has always taken any responsibilities given to her seriously. Her grandparents were Japanese immigrants who came over to America, and her parents also both come from families of immigrants.  But she is very well adjusted to American culture.
