姫ノ宮 雪希

The middle Himenomiya sister. She's a chuunibyou who goes by the name 'Snow Queen Neeju Espoir' and uses archaic speech such as calling her brother 'anigimi' and referring to herself as 'ware'.

She often forces her brother to commit 'rituals' with her which are always sexual. Because her pee is the sacred waters of a magical snow queen she forces her brother to drink it often.
