Katyusha Akae (赤江 カチューシャ Akae Kachūsha?) was Kureha's classmate, a member and one of the leaders of the Invisible Storm. Katyusha is seen putting down with bear warning signs during an alarm in the first episode. She is later killed and eaten by Ginko and Lulu, with her iconic headband preserved, and is used to lure Eriko to the flowerbed for eating. Katyusha was the Invisible Storm leader who outed Sumika for refusing to exclude Kureha. In the manga, she works under Yurika as a maid.
