Hannah

Hannah is a young German girl who became separated from her mother during a visit to the Ramen Museum. It was there that she crossed paths with Koizumi, and she quickly took a liking to her. The two ended up sharing a bowl of ramen together, with Koizumi treating her to the meal. The restaurant staff, apparently noting Koizumi's distinctive alkaline-water yellow hair alongside her outfit at the time, seemed to mistake the two for members of the same family. Hannah's mother was also present somewhere in the museum, and the two were eventually reunited.
