Maria van Hossen

As the energetic and charming younger sibling of the van Hossen sisters, this spirited girl brings a lively warmth to her family. She shares an incredibly close bond with her father, Vincent, often seeking his constant affection and companionship. Already viewing Teppei as an older brother figure, she affectionately calls him "Onii-chan," anticipating his future place in the family should he marry her elder sister, Sylvia.
