Tokyo Ghoul looks at the city from a corrupt and merciless perspective, as vicious evil creatures called ghouls now exist alongside humans. The worst part of it all is their ability to take the form of humans and blend in with the rest of society. Ken unfortunately meets his demise when he is confronted by a ghoul he knew, leading him down a dark path of uncertainty. After he awakens and sees the outcome of the previous event, he now realizes he has transformed into a half ghoul, half-human and must now find a way to blend in with the evil corrupt community.

Izumi and Kei are driven into a world of the unknown and must now come to learn of their dark future that lies ahead. They both were taken out of their comfort zone without permission, which led them into a chaotic and bloodthirsty atmosphere where they need to come up with the right solutions to survive. Every direction they head in is full of mystery, as the enemy is always tracking down their every move with the intent to erase them from existence. Strategy, planning, and outmaneuvering their opponents is how the two must survive, otherwise they run a huge risk of being outplayed by the opposition. Both shows are a game of chess, where each step you make can only lead you closer to the check mate so everything matters.

After succumbing to the full effects of Pupa, Yume undergoes a eerie transformation into a monstrous creature with an rapacious desire for flesh; Utsutsu, on the other hand, is only partially affected, gaining the incredible power to regenerate at will. Ensuring to keep the promise he made to himself years ago, Utsutsu is willing to sacrifice everything in order to always be there for his little sister. Pupa tells the story of a loving brother's desperate attempts to save his sister, while protecting the world from her uncontrollable hunger.

The great similarity between the two is how both enemies have the unquenchable thirst for blood, and must devour other humans in order to survive. Yume and Utsutsu have to use their abilities to survive, even if it means to eating other people. Izumi's enemy have that very same ability as the aliens that burrow into a body must eat other humans to maintain their energy, and grow in strength. Both shows leave you questioning what could possibly happen, as each scene leads you down an uncertain road, and the enemy always planting different traps to throw you off. It shows us cannibalism in the extreme extent, which is just a reflection of how our own reality must cope with these sorts of problems on a daily basis.

Shinsekai yori tells a fascinating story of Saki and her friends as they journey to grow into their roles in a Utopian based world. Accepting these roles, however, might not come easy when faced with the dark and twisted truths of society, and the impending havoc born from the new corrupt world.

Two opposing factions are neck and neck with eachother, as one tries to outsmart the other in a battle for supremacy. Izumi and Saki are thrown into uncharted territory where they must now face the shocking reality that lies in front of them. The premise of both stories are that each main character must confront a challenge, and each new one presents a much higher difficulty than the last. Certain scenes throughout both shows blur the line between what's good or bad, and so the viewer is drawn into these events along with the protagonist. Both anime question the judgment of the two characters, but also leave you scratching your head as to what you would do in that very moment.

A race of cannibal monsters called the Shokujinki exists and it is the job of the Kifuuken, an elite group of beast-hunters, to stop them. Toshihiko, an expert swordsman and son of the Kifuuken organization's leader, puts himself in an awkward position and falls in love at first sight with a beautiful girl named Yuka; however, to Toshihiko's surprise he comes to realize that Yuka is in fact a Shokujinki.

Kemonozume explores a territory that most find very gruesome and inhumane. The truth is that this type of ruthless behavior exists in our reality, and has existed throughout our life span. Cannibalism is the act in which one human thrives off the flesh of another human, in order to survive. In both shows, there exists a race of monsters that have come to Earth to feed on unsuspecting prey, and to take control over the human race. Toshihiko much like Izumi, come across these monsters on a daily basis, and at some point must build relationships with a few in order to survive. Their lives become a race in order to stop the major threat that inflicts suffering upon society before all of humanity is wiped out.

Humanity has been pushed to the brink of extinction following the evolution of man-eating monsters called “Aragami”. They conquered their territory, devouring almost everything in their path and leaving nothing behind. To defeat them, an organization named Fenrir was established as Earth's answer to save humanity through the use of “God Eaters. One such God Eater is Lenka Utsugi, a New-Type whose God Arc takes the form of both blade and gun.  Lenka must master his God Arc if he is to fulfill his desire of wiping out the Aragami once and for all. The monsters continue to multiply while the fragments of humanity struggle to survive.

God Eater. much like Parasyte, features characters who have acquired their ability from the enemy, and now must use that very same power against them to protect Earth. Both Lenka and Izumi must form a bond with their weapons and master them before the threat becomes too big to handle. Each must form an alliance with various individuals in order to seek out more answers behind the invasion, and use the data to outwit their opponents without harming too many casualties. It's an action packed adventure that leaves you guessing at every moment, as to what could possibly happen to the main character if they make one fatal mistake.

The story starts off Jin Kanzaki, a young man with the ability to transform into a superhuman being known as Zet, and Kouga Amagi, a young man with a strong sense of justice who uses technology to fight as Alphas. The fates of these two men and those around them come together as they fight to protect mankind and destroy monstrous man eating abominations known as Players.

The Players in Zetman have a similar mission and that's to burrow themselves into the skin of innocent humans, and using them as tools for their destructive purposes. Both main protagonists must join an organization that have all the answers to their existence, and must use this information to destroy the enemy before it's too late. Kouga and Jin work as a team using their superhuman powers to fight off evil, much like Izumi and Migi in their world. Their fate relies on their ability to work together under severe pressure, while unveiling the weak spots of the enemy and eliminating them as swiftly as possible.
