Momochi-san Chi no Ayakashi Ouji - Episode 10

In the tenth episode of "Momochi-san Chi no Ayakashi Ouji" titled "Regal der Herzen," a series of confrontations and revelations unfold, centered around Nachi's manipulation of Aoi and his ambition to become an Ayakashi. The episode begins with flashbacks showing the first encounter between the young Nachi and Aoi, where Nachi exploits Aoi's ability to see Ayakashi to draw him into his plans. Nachi confesses that he seeks the power to control Ayakashi and targets Aoi as the key to the Momochi household's power, leading to Aoi becoming the Omamori-sama.

Nachi's plan advances as he captures Aoi, Ise, and Yukari, revealing his intentions and his disappointment with Aoi's excessive potential to Himari. He explains his strategy to weaken Aoi through emotional manipulation, particularly through Himari's influence, which causes Aoi to regain her humanity and lose the balance necessary for Nachi's control.

When Himari attempts to intervene, she learns from Kasha that Aoi and the others are trapped in an inaccessible realm. Determined to rescue them, Himari is guided by a winter cherry lantern to the Regal der Herzen, a metaphysical space where the memories and fates of people are stored.

Himari encounters Hakka, the gatekeeper, who presents her with a choice: either explore her own drawer to learn about her parents or open Aoi's drawer to find a way to save him. Despite the temptation to uncover her parents' past, Himari chooses Aoi's drawer, symbolizing that she prioritizes the people she cares about over her own desires.

The episode ends with Himari gaining access to Aoi's memories, ready to learn more about his past and potentially find clues to rescue him and the others.
