Anime Review: Daemons of the Shadow Realm

Sibling strife and plenty of intrigue in the new anime from the creator of Fullmetal Alchemist

Sibling bonds and sibling conflicts are frequent themes in popular anime. Powerful examples include Sasuske and Itachi in Naruto, Asta and Yuno in Black Clover, and Demon Slayer’s inseparable sister-brother duo Tanjiro and Nezuko. Sibling relations are often a side story in many adventures, adding emotional depth to the characters. In some stories like Fullmetal Alchemist, the sibling relationship is the primary story. Daemons of the Shadow Realm is a new fantasy anime from the creator of Fullmetal Alchemist which brings sibling drama back to the center of the story, but with a twist. Kind, down-to-earth Yuru will do anything to protect his twin sister Asa until he finds out that Asa is not who she appears to be. Neither is his cozy medieval village what it appears to be. The new series is full of plot twists, family angst, lots of betrayal, and plenty of magical creatures who are invisible to the rest of society. In addition to the intriguing premise, the story keeps viewers engaged with its movement between adventure, humor, and very graphic violence. Holding the diverse cast and action-focused plot together is the primary protagonist Yuru, whose particular balance of pure-heartedness and clever, wise cynicism is a refreshing change of pace from the usual shonen heroes.

[SPOILERS for the first episode] Teenaged Yuru lives in a small medieval village with his twin sister Asa. Legend has it that twins born on opposite sides of midnight will have magical destructive power (the power to sunder day and night). This leads to a quiet power struggle by outside forces to control or destroy the children. After their parents disappear, the children are raised by the village. Yuru is mentored in hunting and fighting skills but, for unknown reasons, Asa is kept locked in a cell by the village elders, and Yuru won’t leave the village to search for his parents because he refuses to leave her behind. Despite the strange arrangement, Yuru has strong friendships and support in the village, and remains close to and protective of Asa. But things aren’t what they seem, and everything changes when outsider assassins attack the village and brutally massacre most of the adults. They are led by a dark-haired teen girl who looks somewhat familiar. Yuru and his mentor Ryu (also known as Dera) are able to skillfully defend themselves, but Ryu decides to take Yuru and flee the isolated village. Yuru refuses to leave his sister behind and vows vengeance against the lead killer. But the assassin shares some unexpected news: the little sister he’s been protecting is a fake designed to trap him in the village, and the brutal murderer in front of him is his real sister, who’s been searching for him for years. Then, as he and Ryu flee the magically protected village, Yuru is suddenly exposed to cars, cell phones, and skyscrapers. We learn that Higashi Village is trapped in time but surrounded by contemporary Japan. It’s a lot to take in, but Yuru is surprisingly level-headed as he navigates a completely new world. In the process, he forms a contract with a pair of powerful daemons who fight to protect him. As the world battles around him, he must navigate his powers and fight off those who seek the control him and his sister. All of this is mostly hidden from the rest of the world. Only certain people can see daemons; few people can reach Higashi village, which is hidden from the rest of the world by magic.

But are the people of Higashi Village trying to protect Yuru or use him? Asa has been raised by the powerful Kagemori clan, whose manipulative wealth and crime connections make their intentions suspect. The story is filled with lots of betrayals, plot twists, and power struggles that keep the story enjoyable. But there are also enough sentimental moments to keep the story emotionally anchored. Cynical Ryu becomes a reluctant father figure to Yuru in their modern urban apartment. There are some fun fish-out-of-water moments as Yuru and his giant shadow daemons discover the wonders of modern living. But, despite being mystified by seemingly magical gadgets, Yuru has been raised with strangeness as part of his life, so his humorous fascination is always moderated. The idea of something he can’t understand is already a part of his being. This element is a fun exploration of the wonder of magic versus the wonder of science. And his curiosity is balanced with his solid instincts and a healthy dose of cynicism. After being abandoned by his parents and lied to by those he trusts, and witnessing the massacre of his community, he is not easily fooled by the smooth-talking manipulators who are trying to access his power. Asa, on the other hand, is fierce, cutthroat, and brutal, but she unexpectedly loves intensely, and is completely devoted to the brother she lost. Yuru treats her with bitterness for killing his village, but also with suspicious curiosity, as she genuinely dotes on him and tries to connect with him. Although he won’t forgive her for what she’s done to try to find him, he understands that there are larger issues at play, since control over the combined power of the twins will affect the safety of the entire world.

The pairing of opposites working together is a consistent theme throughout the story. Yuru and other magic wielders have pacts with supernatural beings called daemons. The daemons exist in pairs with opposite identities. Yuru’s daemons are the strong, giant, ancient, male and female warriors named Left and Right, who are fun characters with gorgeous animation and character design. The central story focuses on the twin protagonists who symbolize Day and Night. Yuru represents night and the power of “seal,” locking things down or bringing closure. Asa represents day and the power of “break,” destruction or opening to freedom. The duality symbolism is fun, and many of the various magical characters have their own quirky personalities. Beyond the core characters, the story builds outward with a growing cast that includes the various factions fighting to control the twins. Fortunately, the characters are introduced gradually, which makes it easier to keep track of who everyone is. Other than Yuru, almost all of the characters are morally gray, including Asa, who has no remorse for slaughtering people to get to her brother. This dynamic keeps the tension strong because you never quite know when someone is going to suddenly betray a character. Fortunately, Yuru understands the realities and is clever enough when dealing with the various factions trying to get to him. His balance of youth, curiosity, cleverness, and cynicism makes the show highly watchable without falling into the more common protagonist tropes of either excessive optimism or grumpy bitterness. And the quirky relationship between the lethal siblings is a nice change of pace from the more common protective big brother themes.

So far in season one, Asa feels much less developed than Yuru, but neither of them have extended deep moments of introspection. Fortunately, the brief moments pack a lot of meaning and keep the story grounded. In one passing moment, Yuru realizes and comments out loud that his parents left him behind. There’s not a lot of drama, but viewers can feel the gravity of the hurt in that single sentence. Elements like this keep the show entertaining and engaging despite the growing cast of characters. The show’s premise feels typical, but the delivery is clever and unexpected, with plenty of early plot twists. Additionally, the story gives us a unique and intriguing sibling dynamic that differs from the usual setup of protection or rivalry. Both Asa’s and Yuru’s love for each other has been twisted, leaving the twins to navigate not only the forces battling to control them but also their own personal connection that was brutally damaged through the actions of others. That internal tension is a great way to balance an action-oriented plot in this unique fantasy setting.

Nerd Coefficient: 8/10.

Highlights:

  • Refreshing change of pace in the protagonist and relationship set up
  • Complicated cast of morally gray characters
  • Solid action with plenty of violence
