|First Appearance||Legend of the Golden Witch (mentioned)|
Asumu Ushiromiya (右代宮 明日夢?) was Rudolf Ushiromiya's first wife. She died six years prior to the start of Umineko no Naku Koro ni and is initially believed to be Battler Ushiromiya's mother. Asumu never directly appears in the story but is mentioned frequently in the game's dialogue and TIPS. Asumu and Kyrie Ushiromiya both became pregnant by Rudolf at roughly the same time. However, Kyrie's child was stillborn and Asumu's lived.
Upon Asumu's death, Rudolf immediately remarried with Kyrie, leading Battler to believe that Rudolf had betrayed Asumu. Battler then cut ties to the Ushiromiya family for the next six years. While she is vilified by Kyrie, it is hinted that Asumu was vastly different than how Kyrie described her. It is implied that Asumu was actually a gentle woman that Rudolf married out of love rather than obligation.
