Atsuko is Lazar's wife. Her face has a striking resemblance to her husband's face. She seems to be a very kind woman who cares deeply for her husband and son. She witnessed Lazar's defeat to Crow, but still loves her husband as he lost the duel to protect her family from Yliaster.

She was later seen walking into the bus along with parentless children and Martha to escape from the city when the Ark Cradle made an appearance.
