Nanao, Ren

七々尾蓮

Ren and Ai are twin first-year students at Kouta's school, making their debut in the fifth volume of the novels. As spirit hunters residing in a destitute temple, they are often observed engaging in behaviors typical of homeless individuals, such as preparing stew from garbage and roadside weeds or consuming discarded bread crusts. Although initially tasked with assassinating Chizuru, they refrained from carrying out the mission because she was "only a kid." The twins are nearly indistinguishable, differing only in their slightly varied hairstyles, and they employ chains during combat.
