Yandere Dark Elf episode 4: Cecile and Mei's arrival infuriates Mariabelle

Picking up the events from the previous episode, Yandere Dark Elf episode 4 begins with Cecile telling Mariabelle that she and Mei have come to take her back home. Hinata looks confused and asks them how they arrived. Just as Cecile is about to reply to Hinata's question, Mariabelle interrupts, unleashing her inner fury.
She becomes furious at Cecile and Mei for meddling in her affairs, calling it "unacceptable." However, Cecile clarifies that she intervened to save Hinata from Bell. Meanwhile, the commotion draws in onlookers, who wonder what's happening. Mei quickly steps in to prevent Bell and Cecile from arguing with one another.

Hinata also realizes that they should get out of there. As such, he invites Cecile and Mei to his home. Yandere Dark Elf episode 4 then shows Hinata welcoming his former party members. He mentions how glad he is to see them doing well. The episode reveals that Cecile is a priestess who serves the Gods, while Mei is a demihuman.
Meanwhile, Mariabelle snaps at Cecile for showing up uninvited and crashing her and Hinata's "Love Nest." In response, Cecile reminds Bell that it was Hinata's suggestion to discuss the matters at his home. Additionally, she questions whose fault it is that they find themselves in this situation in the first place.

Cecile wonders if Bell understands the chaos she has caused by arriving on Earth. According to Cecile in Yandere Dark Elf episode 4, the existence of the other world was meant to be kept a secret. If this information becomes widely known, there's no telling how the two worlds might influence each other.
That's why Cecile and Mei are dispatched on the government's orders to retrieve Bell before something goes wrong. She adds that Mariabelle will be pardoned for her commendable victory against the Demon Lord if she complies with the government's wishes and returns now. However, every word goes over Bell's head, as she believes it's a ploy to separate her from Hinata.
Yandere Dark Elf episode 4: Hinata's assurance and Mariabelle's bold play

At this moment in Yandere Dark Elf episode 4, Mariabelle emits her Yandere aura as she refuses to part ways with Hinata. Meanwhile, Cecile is resolute in following the authority's orders. As a confrontation is about to erupt between the two, Hinata intervenes.
Hinata understands why Cecile and Mei have traveled to his realm. However, he recognizes that there are those in his world who will accept Bell for who she is. Most importantly, he feels happy when Bell visits him. That's why he is ready to take responsibility and urges Cecile and Mei to allow Bell to stay with him.

The priestess doesn't say anything to Hinata since he has given his word. Therefore, she leaves the dark elf in his care. After that, Hinata asks Cecile and Mei why they are leaving so soon. The priestess mentions there's no point in their hanging around any longer. Cecile then smiles at Hinata and prays that the gods will protect him.
Once they leave, Mariabelle's yandere aura takes on a new form. She remembers Hinata saying that he would take on her responsibilities. Yandere Dark Elf episode 4 then shows Mariabelle tempting Hinata with her bold gestures. Bell's temptations are intoxicating for Hinata, leaving him unsure of how to stop her. Yet, as she makes a bold move on the boy, a magical spell gets activated.

Mariabelle realizes that Cecile is behind the act and curses the priestess for ruining her mood. The next day, Cecile and Mei stop by Hinata's house to inform him that they are now his next-door neighbors.
Cecile explains that she and Mei have been instructed to keep an eye on Bell in case something goes wrong. Yandere Dark Elf episode 4 ends with Mariabelle angrily shouting at Cecile and Mei to leave.
Conclusion
Yandere Dark Elf episode 4 was another installment, primarily focused on Mariabelle's obsession with Hinata. She refused to return to her original world, as that would sever her connections with the boy.
However, Hinata's assurance meant that Bell could stay with him. At the same time, Cecile and Mei's vigilant eyes ensured that Bell couldn't run amok with her feelings for Hinata.
