In I Don't Want This Kind of Hero, the universe is a lot like Earth, but with the main differences being the existence of magic. 

Mythical Beast 

Main article: Mythical Beast

Mythical Beast are normal living things which grow much larger than normal and gain a longer life span, eventually, they grow big enough and turn into humans, the theory for this in-universe is because humans are the top of the food chain.

Mythical beasts can be a variety of things ranging from plants to animals and in one case an action figure. Although this is treated as an anomaly.


Main article: Hybrid

Hybrids are the children of Mythical Beast and humans, they retain different parts of their Mythical Beast parent and in different percentages. Currently, they are more commonly found than Mythical creatures and heavily discriminated against by some humans.

It's shown that most people have come to accept more cute looking hybrids but hybrids of predators or animals that are generally considered scary or disgusting are more looked down upon (see: FORK arc).

This change in behavior is very recent and most likely due to the creation of FORK, as you can see in Raptor's flashbacks when going into town she covers her ears and didn't feel safe going into town.

The growth of hybrids differs to humans. In some cases it is faster in other cases it is slower.

They are somewhat aware of what animals in the same species are saying.


Superpowers are a rather common occurrence in-universe with most people harboring some sort of ability which makes them superhuman, this can be something naturally possible due to genetics or something caused by unknown/outside variables. There is also a case of superpowers being caused by a disease.

Superpowers which are genetic or cannot be controlled are not referred to as "superpowers". This is because superpowers cannot be inherited.

Right now in terms of power, Naga is the strongest, previously Youngjeong, however all variables considered Amore would be the strongest as they are naturally beloved by all living things and gods, can see all and can force people to repent.

Superpowers are heavily impacted by the user's emotions, some powers don't seem too affected by this but others can become more unstable or weaken with emotion. If a user reaches a certain constant of emotion their power can completely change.

Superpowers can also be blocked. There are some people with abilities to block the powers of others and there are some people who can control the "flow" of superpowers. The executive committee was creating a gas which could block superpowers for a limited time once inside the body.

Anyone with any sort of above average ability, this can even include singing or drawing are called specialists (not "psychics" which is how it is localized).


While it seems the general public still considers superheroes to be people in flashy costumes and capes. In this universe, superheroes work as government officers on a higher level than the police. It seems the requirement to become a superhero is to just be superhuman in some sense or shape, however there are workers who are not superhuman but still work there.

While superheroes do tend to wear a uniform of some kind, though everyone at SPOON excluding a few select people wears the same thing to work every day instead of casual wear) they don't wear anything that makes them stick out of a crowd. Superheroes aren't very popular or well known with the general public. For this reason, SPOON agents have to pretend to be police.

Despite this, they still get many mundane complaints and tasks which the police would be better suited for,

Despite how common superpowers are many are not strong enough to be used in battle, for this reason, SPOON is heavily underpowered with very little workers.

Invincible people

(Localised as immortal god)

Creatures who have been around for an unknown amount of time who never die. There are many different species of this race, in this story we see two: Winged people and horned people.

  • Winged clan

It seems they have been around since even the middle ages, in the past, they were deemed to be angels because of their wings in the modern day however most people assume they are hybrids.

They consider each other brother and sister and all of them remain in contact even if they live far away. Many of them have lovers or children but they never end nicely as their loved ones always outage them. Sometimes when people learn of their ability to regenerate they are disgusted and stay away from them. For this reason, some of them try to avoid letting others find out.

This species specifically gets praised and worshipped as something similar to gods, however, they are nowhere near powerful. Abilities specific to them are healing.

  • Horned clan

It is unknown the earliest they were around however for a period of time they were held captive for the pearls produced by their blood or tears. Unlike the winged species, they do not have the ability to regenerate or heal their wounds naturally. They also don't look human so in the past, they were considered to be demons.

A big difference between the two is there attitude towards mankind. Horned people despise humans and only use them or work with them for their own goals. During their arc they implied they wanted Naga and Youngjeong to kill each other so they could steal their powers, they also ran away in the first place so Youngjeong wouldn't find them and ask them for anything, and they also made Dana promise her body to them if she told people where they lived.

Additionally the gifts they gave both Youngjeong and Naga were revealed to only contain a few powers. Most of the gems didn't have any ability stored within them.

On the contrary the winged invincible people are shown to greatly adore humans and are willing to live among them. They follow human legislation and human social rules and in most cases have human family members.

However in some cases it seems they may not truly care about what happens to humans as a whole if they can look after a human that is important to them.


A gem created from the tears of horned invincible people. It is strengthened when mixed with other bodily fluids, such as blood.

The horned people primarily use it to capture the specialty of people who hunt them so they can use it for themselves. However, because of their nature, some of the abilities are useless, like looking young.

Even if the gems break they can use their tears to repair them. But they are the only ones who can fix them.

There are many types of perfection seen throughout the comic:

  • Ice ability perfection: This perfection gives the user the ability to turn into a presumably cold gas and blow cold air out of their mouth. It was originally owned by Salt Bora before it was stolen by KNIFE and then put into the possession of SPOON, indicating that Sewol most likely had it.
  • Telekensis perfection: A perfection that grants the user the ability to use powerful telekensis, since Water Bora(the owner) could not use it to lift up the Horned People's home it is most likely strong enough to put the sea apart but not strong enough to carry pieces of land.
  • Confusion perfection: A perfection which confuses the senses of everyone except the user when they use their superpowers. It has no effect on the person's powers like Lady's ability. It was originally owned by Salt Bora who gave it to Number 2 temporarily, before taking it back and having it stolen by KNIFE. While KNIFE had it, it was used by Orca.
  • Aging prevention perfection: A perfection which keeps the user's body young, it is unknown if it prevents dying of old age or diseases. It was gifted to Youngjeong as a present before it was smashed by Baekmorae.
  • Clairvoyance perfection: A perfection originally belonging to Salt Bora but was in the hands of KNIFE until the end of the comic. It is used by various members for various purposes. Baekmorae used it to watch Naga and Dune's conversation and watch Naga and Youngjeong's fight, Medusa used it to watch over SPOON on various occasions and Sewol used it to find out where Naga was going to be when she promised to help Lady with her love life. It is presumably taken by Raptor after she captures Medusa.
