17 years ago, immortal beings known as Ajin were discovered in Africa and immediately designated as dangerous entities that must be captured immediately. It is impossible to know whether you are an Ajin or not until you are in a situation where you should have been killed but you managed to survive. That is exactly what happened, when the studious Kei Nagai is hit by a truck walking home from school and is not only able to get up after the accident, but all his wounds heal in front of the onlookers. Soon after, Kei goes on the run in fear of being captured by the government. After seeing Kei on the news, his good friend Kaito decides he will help Kei escape no matter the cost. Kei and Kaito soon learn that not only are they being chased by the Ministry of Health, Labor, and Welfare, but also a group of Ajin whose intentions are unknown.

Similar to Kokkoku, Ajin features heavy supernatural elements, with supernatural powers and different types of monsters that are much more powerful than humans.The main characters also share how they came about gaining their knowledge of their powers, as Kei and Juri are both unaware of their powers and only awaken them when they are faced with death early on in both series. The Ajin and the Handlers not only look kind of similar, they also both operate in similar fashions as well, with the Ajin protecting the person they are bound to, whenever they are in danger and the Handlers protecting anyone who can't move in Stasis. Both shows also have a decent amount of death and gore that occurs regularly.

The main similarity that Boku dake ga Inai Machi and Kokkoku share is that both shows rely heavily on the main characters ability to alter time. Satoru uses his Revival ability to go back in time multiple times in the series to help uncover the truths behind the murders in both the past and present and Juri use her Grandpas stasis ability to pause time. Both Satoru and Juri use the altering of time to investigate the mysteries they are faced with.

Much like Kokkoku, Inuyashiki features many scenes filled with action, violence, and gore. With all of these aspects combined with the dark city setting, Kokkoku and Inuyashiki give off very similar vibes. Ichiro Inuyashiki and Jiisan are similar characters with both of them being older men that are main characters in the story that have supernatural powers that they must use to battle against others who have the same powers. Ichiro also shares similarities with Juri as both characters are getting used to their new powers and they are learning all about these new powers at the time as the viewer.

Steins;Gate and Kokkoku both have major story elements that revolve around the altering of time and a small group taking on a larger group of bad guys trying to use those same powers for evil.

After seeing their classmate Miyuu Aikawa talking about fortune telling on television, Yuuta and Ryoka decide to interview her to help drive traffic to their blog. Miyu not only agrees to the interview, but she asks to join Yuuta's team. Ryoka and Miyuu then suggest that Yuuta interview Professor Hashigami who was known for his research on the occult. When Yuuta arrives at the professor's classroom, he finds a bloody knife on the professor's desk and then finds the professors dead body on the ground. Yuuta is then thrown into a world full of mysterious people with supernatural powers brought together by his blog. Together with all of these people, Yuuta starts to learn more about not only the murder of Professor Hasigami, but many other murders and mysteries that are happening around him.

Occultic;Nine and Kokkoku both feature large casts of unique characters and deep plots with many moving parts, but Occultic;Nine does this in a slightly different way than Kokkoku. Occultic;Nine uses its many main characters to give different perspectives on the story giving the viewer all the info to piece together the mysteries that are happening. Kokkoku gives the viewer the same feeling of learning about the bigger picture of the world, but it is done with the background of the supernatural powers and the people who use them. Both shows also work at a fast pace giving the viewer a lot of information to take in and keeps throwing that info episode after episode, allowing the viewer to take in a lot of pertinent information, but keep it at a reasonable level so that it doesn't get confusing.

Zankyou no Terror starts out with a terror attack on a nuclear facility in Japan, where two men manage to steal plutonium.

Despite the pair directly challenging the police, their threat is taken as nothing more than a prank. After Sphinx's first attack the city is thrown into the panic with the police unable to come up with any leads as to the identities of Sphinx, they decide to bring in Detective Kenjirou Shibazaki to lead the investigation into Sphinx. Zankyou no Terror tells the story of Nine and Twelve, the boys behind Sphinx, and the reason behind their attacks on the government.

On the surface, Kokkoku and Zankyou no Terror may not seem like they have very much in common, but when you look a little deeper into both shows have very similar aspects. Both anime show the darker side of the world with Zankyou no Terror featuring criminal organizations, a corrupt government, and protagonists who could be viewed as antagonistic to the average person in their world. While Kokkoku doesn't share all of these themes, it features a criminal organization working in a world filled with monsters that the average person has no knowledge of. Juri also shares some similarities to Lisa, not in the characters themselves bu more in the journeys the characters take in the story. Both Juri and Lisa are dragged into the story by pure happenstance, with Lisa being near the place of Nine and Twelves first attack, and Juri being related to Jiisan who has the ability to enter the Stasis world.
