This article is about a character in Umineko When They Cry.

Kasumi Sumadera (須磨寺 霞 Sumadera Kasumi) is the younger sister of Kyrie Ushiromiya. Since her sister married with Rudolf, she bore extreme resentment towards Kyrie, to the point of loathing everything about her sister, including her niece, Ange Ushiromiya. She first appears in Alliance of the Golden Witch.


Daughter of the declining noble family, Sumadera. Ushiromiya Kyrie's younger sister.

She despises her sister, and by extension, Ange as well.

She's the opposite of the freewheeling person Kyrie once was and holds appearance in high regard, possessing a strong ambition for philanthropy. However, this is all just a craving for the limelight caused by the complex she has towards her sister.

There are several opposing factions in the Sumadera Family, and they're constantly engaged in a secret feud over who will control the vast wealth Ange holds.



Kasumi has silver hair going off to the side and wears a purple kimono.


Kasumi is very vindictive, showing contempt for Kyrie for abandoning her family and towards Ange just for resembling her.


Kasumi and Kyrie were part of the Sumadera family, a sort of rival to the Ushiromiya family. After Kyrie left the family to marry Rudolf, Kasumi was forced to break up with her fiancé and marry the man her sister was supposed to marry. Saddled with the pressure of becoming the new Sumadera family head, Kasumi bore hatred for her sister and anybody related to her.


Role in the Games

Alliance of the Golden Witch

Kasumi is first seen as the woman pursuing Ange. Ange notes that she only appeared after Eva Ushiromiya died and Ange inherited the "cursed gold". Tetsuro Okonogi, when ordered to stall Ange so that Kasumi could "take her to tea", allowed Ange to escape. Kasumi, upon learning this, pities the fact that Ange avoided her once again, and sent her men after Ange. When one of her men caught Ange, however, Juuza Amakusa appears and rescues her. Kasumi is then disappointed by the turn of events.

Kasumi reappears at the end of Alliance, awaiting Ange on Rokkenjima. She has Ange beaten by her henchmen as she told Ange why she pursued Ange. Kasumi was envious of how Kyrie had abandoned the family, and, instead of being punished, had the position of Family Head pushed onto her. She continued to remark how Kyrie could be happy, while she was suffering. When Ange questioned Kasumi's motives for beating her up, Kasumi replied that it was because Ange looked exactly like Kyrie.

EVA-Beatrice's spirit appears next to Kasumi, goading the latter into taunting Ange about Maria's diary. Taunting Ange to show her magic, Kasumi proceeds to rip up Maria's diary, angering Sakutarou and Mammon, who were watching.

Ordering one of her guards to shoot Ange, Kasumi becomes shocked when the man is instead impaled in the heart. Just before, Ange had summoned The Seven Stakes of Purgatory, who not only protected Ange from the bullet but also killed the man. Although the Stakes appeared behind Ange, Kasumi and her henchmen could not see them because they had no love.

Ange warns Kasumi's men not to fire or else they would die, but they fire anyways, effectively getting killed by the Stakes. Kasumi herself is also killed soon after.

Dawn of the Golden Witch

Kasumi does not appear, however in the Tea Party, Okonogi makes a secret phonecall to Amakusa and asks him to assassinate Kasumi and her men.


  • Kasumi's name is written with the kanji 霞 while the "kiri" of Kyrie's name is written as 霧. Both characters mean "mist".
