MujiEmma is the friendship between Emma and Mujika from The Promised Neverland fandom.

Canon
Emma and Mujika's have a very close friendship. They can confide anything to the opposite party, care about each other's wellbeing, and trust one another deeply. However, things weren't always like this between the two, since their relationship had a rocky start. After escaping Grace Field, Emma collapsed due to her ear mutilation. That's when her and Mujika meet when her and Sonju save the Grace Field children, as well as Emma and Ray. Since they took care of them and took them to their hideout, and since Mujika looked like a human to Emma, she never even suspected she was a demon. So she gets shocked when Ray confronts her and Sonju asking them if they just brought them there to eat them. Emma, terrified of what could've happened to her siblings, runs to them and realizes they're not only alive, but also well-fed and happy. That's when Mujika and Sonju reveal the reason why they don't eat humans is because of their shared philosophy to not eat humans from farms.

For the next days in their journey to escape the forest by traversing an unknown path underneath the forest, Emma learns all of he essential knowledge she and her siblings need to survive, as well as the horrific conditions in which the children in mass production "cheap meat" farms are. After that revelation, Emma has a heart-to-heart conversation alone with Mujika, who asks if she is fine after Sonju's disappointing revelations. Emma says that it is fine, and that even though what was revealed was a shock, they will be able to find a way to secure a new place and recruit more people to help them; that she can't afford to sit around and do nothing. Mujika is surprised by her sudden change in mood, and Emma then asks if she wants to see her family pictures, and shows happy pictures of the children that they left behind, before getting to Norman. Then flashbacks of him and the promised she made to him come back to Emma, as she says she will never forget to never give up and to never lose another child and free them all, like she promised to Norman.

Mujika gets impressed by her words and thinks to herself that Emma had no choice but to embrace the audacity within her. Emma then interrupts her thoughts by saying that she can't think of Mujika as a demon at all, because of their kindness, compared to the bloodthirsty demons that sought to eat them. She does not reply, and in a demon language, says "True enough, in these thousand years we have decayed into disarray...", before changing the subject, saying that this is the first time she got to see and talk to humans, and become their friends, instead of enemies or food. Mujika then tells Emma about how happy she is of having met her and her friends. And Emma does the same, thanking her for the six days they spent together.

The next day, before the kids' departure, Sonju and Mujika say their farewells to them, reminding them to stay safe. But Mujika pulls Emma into a hug and gives her a necklace as a "good luck charm", and gives her an immensely important message that Emma will never forget. From that day onward, the whole story will showcase just how much importance and impact, as well as how dear Mujika is to Emma. She has never stopped wearing the necklace Mujika gave her; she is seen completely distraught by the mere suggestion Norman makes of killing Mujika, "the girl with cursed blood"; she refuses to let Mujika be killed, claiming that she would never be able to smile in a world that let her dear friend get killed. The reason Emma went to search for the Seven Walls, a very dangerous task, was to avoid Norman's plan of extermination of the demon race, and by extent, keeping Mujika and Sonju safe. Emma later admits that her compassion of demons and not wanting to get them all killed was because of her meeting with Mujika and Sonju. Because of this, Emma developed the thought that if she was dying, she would be fine with Mujika or Sonju eating her. All of this showcasing just how much of an impact Mujika made on her.
