Quark (クオーク) was Ram and Rem's father.
Appearance[]
Quark was an adult with blue eyes and hair, and was seen wearing a blue kimono in the brief flashback showing the family together.
Personality[]
He was a loving parent to the girls and cares for both of them greatly. He was especially proud of Ram's gifts, but also takes care to support Rem, though both him and his wife don't really seem to understand their younger daughter's internal struggles. Even so, he reacted very positively when Rem challenged herself to be more like her sister and cooked dinner.
