15 years ago, an unknown hyperspace gate opened over the Pacific in Kariaena Island. Beyond this gate lies Reto Semania, a strange alternate world where fairies and demons live. San Teresa City is a city where over two million immigrants live from both worlds. As a result, there are the haves and the have-nots. Here is the world's newest "city of dreams."
But in the shadow of the chaos, crime is rampant: drugs, prostitution, and weapon trafficking. The detectives who stand up to these heinous crimes are in the San Teresa City Police. When the detective Kei Matoba and the alternate-world knight Tilarna two individuals who differ in gender, personality, and even world of origin meet, an incident erupts.
A Police Procedural with a fantasy twist written by Shoji Gatoh, the author of Full Metal Panic! and Amagi Brilliant Park, seven volumes have been written starting 2009. An animated adaptation directed by Shinji Itagaki premiered on July 8, 2019, with a dub made by Funimation released on July 22, 2019.
- Amicable Exes: Kei and his ex are still rather chummy.=
- Bland-Name Product: One case involves an stolen truckload of magazines like Ponthouse, Prayboy, and Heslar.
- Buddy Cop Show: A human police officer and a Semanian Knight need to put aside their differences to save a kidnapped fairy.
- Casting Gag: This isn't the first role for Felecia Angelle where someone from a fantasy world goes to Earth and eventually gets used to living there. Bonus points for also having a sword as a weapon.
- Concealment Equals Cover: A normal sofa is used to stop dozens of machine-gun rounds from an Micro Uzi.
- The Conspiracy: Roth and Zerada plans to use the smuggled fairy into a time bomb and detonate it in San Teresa's tallest skyscraper to turn the upper class visitors into living corpses and cause chaos.
- Culture Clash: The difference between Earth and Semania's way of doing things is very vast.
- Does This Remind You of Anything?: Roth's anti-Semanian rhetoric is similar to the views of some extreme right-wing groups and individuals who campaign on an anti-immigration platform.
- Downer Ending: Kei and Tilarnia aren't able to close the case on the corrupt politician in San Teresa and the potential witness was taken out by an assassin.
- Human Resources: A potent Semanian drug is called "Fairy dust" because it is literally made from fairies. Whole fairies.
- The Illegal: There are a lot of them, both from our world and from beyond the gate, and they are a source of most of the crime in the city.
- Mugging the Monster: Some Semanian thugs try to mug Kei, only for the policeman to beat the shit out of them.
- Neck Snap: This is how the sorcerer-possessed crook killed Kei's partner Rick.
- Off-Model: The show's low production values and questionable direction choices often result in both this and a great deal of Limited Animation both in dialogue and action scenes.
- Our Wormholes Are Different: The hyperspace gate that connects Earth & Semania cannot be seen by human eyes, and can only be detected by satellite scans of environmental fluctuations. On the other hand, Semanians can see it perfectly fine and a lot of criminals use this to their advantage to conduct cross-border smuggling. The coast guard has its hands full just trying to patrol the boundaries of the gate.
- Our Zombies Are Different: An advanced addiction to Fairy Dust makes a person effectively a living corpse and an easy target for control by Semanian sorcerers.
- Pointy Ears: An easy way to identify a Semanian is by their pointy, elf-like ears.
- Snark-to-Snark Combat: Any time Kei and Tillarna are in one scene, is a never ending passive-aggressiveness.
- Tall, Dark, and Snarky: Kei, full stop. What else would you expect from a jagged detective? On her side, Tillarna is small, light and snarky as well.
- They Fight Crime!: Hes a human Cop unafraid to get his hands dirty to solve the case. Shes a proud Elf-like Knight from another world. Together, they fight crime in the mean streets of San Teresa!
- We All Live in America: Kariaena Island appears to be a US territory, like many others Pacific Islands, but the street thugs still behave more like Japanese Delinquents.
