There were two Aiko's working at ggs at the same time, both using the name. Aiko #1 is 100% Japanese, has a sakura tattoo on her stomach, she went back to Japan. Aiko #2 who later changed her name to Yumi to avoid confusion has a sakura tattoo on her back, is also half Korean, she's in NYC, not working at the moment and may or may not return to ggs. Hope that helps.
