In Episode 8, Teru Momijiyama prepares for a trip to Russia as she has a lead on Amarariruku, the mysterious group connected to Stigma. She meets with Pepesha-san, a Russian hero, to investigate a person who resembles someone from Pepesha-san's past.

In Russia, Teru and Pepesha-san visit the Yuri Orphanage, where Pepesha-san grew up. They are greeted by the director, Isaak, and the children. Pepesha-san shares childhood memories and her connection to the orphanage, revealing that her mother, Letana Andreanova, also grew up there.

As Teru and Pepesha-san search for clues in old photo albums, they discover a photo of Pepesha-san's mother Letana, who bears a striking resemblance to Tzveta, a member of Amarariruku. This discovery raises questions about Tzveta's identity and her connection to Pepesha-san's past.

The episode takes a dramatic turn when Mr. Kufufu, another member of Amarariruku, appears at the orphanage and causes chaos by freezing some of the children. Teru and Pepesha-san act quickly, with Teru using her heart-shifting bracelet to communicate and help the children.

Then, Tzveta arrives and confronts Pepesha-san and Teru. She expresses a vague memory of Pepesha-san and the orphanage, hinting at a deeper, possibly personal connection. Tzveta's words suggest that she shares Stigma's disdain for suffering in the world and identifies with his vision of a peaceful, pain-free existence.

The episode ends with Tzveta declaring the orphanage her "place" within Amarariruku, a concept described as an inner refuge free from pain and suffering.
