Katyusha Akae (赤江 カチューシャ Akae Kachūsha?) was Kureha Tsubaki'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 Yurishiro and Lulu Yurigasaki, 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.
- Katyusha's surname Akae means "red" (赤) (aka) and "bay, inlet" (江) (e).
- In the manga, Katyusha works under Yurika Hakonaka as a maid.
