Renate

Renate (レナーテ, Renaate) is the daughter of Otto and Corinna, who was born the same year as Kamil. She will inherit the Gilberta Company.

When Tuuli takes Kamil along for a visit at Corinna, Renate is impressed with how Kamil is able to be roundabout equal to her in Karuta and proclaims that she wishes for him to join the Gilberta Company, so that she can play him all the time until the win-rate is 100%. Ever the doting father, Otto immediately latches on to this and starts pressuring Kamil to join his store. Benno intercedes and states that with Kamil being far more interested in books and toys than in hairpins and clothes, he would be much better off in the Plantin Company, sparking a fierce argument between the two brothers-in-law, until Tuuli eventually breaks them up and tells them to let Kamil decide for himself.
