Asumu Ushiromiya

Asumu Ushiromiya is Rudolf's first wife and Battler's mother, who had died six years prior to the start of the series. She does not appear directly in the story, however, she is mentioned several times, most noticeably in the 'Dawn of the Golden Witch' by Kyrie and in the 'Twilight of the Golden Witch' by Rudolf. Upon her death, Rudolf immediately remarried with Kyrie, leading Battler to believe that Rudolf had betrayed Asumu and he cut his ties to the Ushiromiya family for the next six years. While she is frequently vilified by Kyrie, it is hinted that Asumu was vastly different from how she is described, being a far more gentle woman who was capable of soothing Rudolf's pain, and that he married her not just out of obligation but out of love. According to Battler, Asumu was a very caring mother who loved him very much. According to Rudolf, she was a very kind individual who accepted him for who he was despite his flaws and would forgive his mistakes. Because of this Rudolf wants to protect her. To Battler and Rudolf, Asumu was overall a kind individual. However, Kyrie's perception towards Asumu is almost the complete opposite. According to Kyrie, Asumu was just one of the girls who went after Rudolf during his days as a playboy. However, unlike most girls, she was a very sly individual that was able to stir up an instinct within Rudolf to protect her. She was also noted to be quite smart by both Rudolf and Kyrie as well. Therefore, due to these contradictions, it is unknown what kind of person Asumu was really like. She is initially believed to be Battler Ushiromiya's mother until Alliance of the Golden Witch, when Battler learns he is not her true son when Beatrice challenges him to say the statement in the Red Truth and he finds that he is unable to. Later Rudolf reveals that he got Asumu's and his mistress Kyrie's children switched at birth because Asumu had the stillbirth and Kyrie gave birth to a healthy boy and that was Battler.
