Kasumi Shigure (時雨 霞 Shigure Kasumi) is the Commander of Wärter who is a powerful liberator and partnered with a girl named Hibiki Kenjo, who since suffering a trauma is bedridden. Thus she currently fights without an arm earning her the epithet "Zero Arm".

When Kasumi and Hibiki arrived at the island they were chased down and bullied, after that Kasumi swore to become stronger and cut her hair short after Akira Hiiragi gave her the role of Kommendeur. Her job requires her to ensure the security in the castle. Her partner is Hibiki.

Kasumi is a calm, collected and respectful person. She has also shown to have a kind heart as she opposes (disapprove of and attempt to prevent, especially by argument) Charlotte Scherzen's strictness and often violent resolutions.
