Roselia Haguro

Roselia Haguro serves as the leader of Kayano Elementary's girls' survival game club. Despite possessing an irresistibly cute appearance that even captivates Momoka Sonokawa, her true personality is anything but sweet—she is notoriously mean-spirited and blunt, often addressing her seniors with the dismissive term 'old hag.' On the field, she wields an H&K G36 assault rifle fitted with a scope, establishing herself as a formidable force among elementary-level players. The stark contrast between her angelic looks and her ruthless demeanor makes her one of the most memorable characters in the series.
