Death Note

Light Yagami is a high school prodigy and genius. However, he has an ever-increasing boredom and disdain for the rotten violent world. One day, he happens upon a notebook, called a Death Note, which states that if you write a name in it, the person will die. To his surprise, the notebook’s claims turn out to be true. This Death Note, the property of the Shinigami gods of death, gives Light the power to change this world and he decides to become its new God by executing all criminals.

Death Note is often the series most equated to Monsters because they both detail the descent into madness. In each series, you watch people carry out what they believe is right while exploring the frontiers of good and evil. However, while Death Note has a supernatural element to it, Monster maintains a more realistic approach.

Terror in Resonance

After six months of searching for the perpetrators, the public is shown a video tape of two boys known as Sphinx that take credit for the attack.

The biggest similarity between these two series is that they both have their plot centered around a child that was the result of government experiment. However, the hunt of the series is the same too. Tenma feels responsible for Johan and Shibazaki feels responsible for bringing justice to those behind the plot.


psycho pass anime

In near future Japan, in order to fight crime and bring justice, they have implemented the Sibyl System, a means of determining the threat level of each citizen. Some citizens, despite being threats, are made into Enforcers that work alongside Inspectors to bring criminals to justice.

Despite its future setting, Psycho-Pass sticks to the classic trappings of a crime thriller like Monster. Both series keep a dark atmosphere and actually have the same overall plot of people searching for a ghost killer. However, why so many people like both of these shows is because the antagonists in both Monster and Psycho-Pass are perhaps the best characters of each series.

Ajin is about literal monsters while Monster relies more on the metaphor. However, what both of these series excel in is crafting the suspense. You never quite know what is going to happen next, but you want to find out. Both shows also have characters that work in shades of gray where there are very few truly good characters.
