Ichika describes her friend Keiko as "a gentle, kind, and proper young lady from a good family." She is the type who is easily amused by simple things, such as shaking a duster in a sunbeam. Her parents appear to be rather controlling, however, which causes Keiko some distress with regards to a boy she liked.
