Retzel

Retzel is an infiltration-type autonomous doll produced in Robelia, who was intercepted during smuggling and subsequently placed at the Black Cat Inn. Initially concealing the covert mission assigned by her home country, she carried herself with elegance while delivering blunt and cutting remarks. Through Hizakura's sincere influence, her hostility gradually dissolved. When Robelia issued a self-destruction order, the Black Cat Inn chose to officially take her in, preserving her memories intact. From that point on, she came to regard Hizakura with a reverence akin to that of an elder sister.
