Keiko is a pale skinned woman with brown hair tied into a messy bun and tired blue eyes with rectangular framed glasses. She's somewhat tall and tends to wear simple clothes, usually being seen in an open white lab coat over a blue turtleneck and black pants.
Keiko is a serious woman who doesn't accept anyone pushing her around, no matter their position or importance. She tends to throw herself into her work, sometimes even forgetting to eat or sleep.
