Felt-chan's Royal Election Life From Zero (フェルトちゃん、ゼロから始める王選生活) is a side story featured in Gekkan Comic Alive. It was later adapted in Re:Zero Tanpenshuu Volume 4.
A person, who is assumed to be Ford Lugnica, was carrying his baby with him and was talking with Rom and revealed that he had the same qualities as Fourier Lugnica unlike his older brother Randohal who didn't had the necessary qualities to become the Lion King. The conversation becomes briefly more intense until Ford entrusts Rom and handed over his baby to him. He mentioned that he felt anxiety about the future and wanted to keep his baby safe.
