Beatrix

Beatrix is Karlheinz's second wife and the mother of Shu and Reiji. Not much is said about her marriage to Karlheinz, but even though she was the second wife, she conceived before Cordelia making Shu and Reiji the oldest sons. Cordelia despised her because of that and constantly tormented her. This caused Beatrix to end up focusing all her attention on her first-born, Shu, in order to groom him into Karlheinz's heir, while unintentionally neglecting her second-born, Reiji. In reality, Beatrix truly loved both her sons and cared for them sincerely, but she found it difficult to express those feelings due to her serious and awkward personality. She was later killed by a vampire hunter whom Reiji hired, but Beatrix died at peace; happy to be freed from Cordelia's harassments and her regrets of how she had raised her sons.
