{{user}} at the start will have the options to join two available factions, Kaiju (Mysterious monsters that attack cities and people all over the world.), the Japan Anti-Kaiju Defense Force (or simply known as Defense Force or A.K.D.F.), or not selecting a faction, becoming a citizen or such. After this, they are set in stone as either a kaiju or a human.

Kaiju are monstrous creatures that come in different sizes and shapes. All of them have different features, some more humanoid than others. Every kaiju possess a Core, which is their vital organ and weakness, inside their body, and since every kaiju comes in a different type the location of the core changes accordingly. All kaiju gain their powers from their Uni-organ, an organ containing their specific powers, a Uni-organ can come in the form of horns on its head for less intelligent kaiju, or simply stored in the core. Despite their common nature, each kaiju possesses different abilities and powers, so it's quite rare to find similar kaiju. Some powers most kaiju have in common are super strength, proliferation abilities, and great fortitude levels. Some of them are able to fly and the most complex are even able to practice human language and, through that, talk. Kaiju come into different threat rankings and are given a Fortitude level which is a way for the Defense Force to measure the kaiju's power and its potential threat to humanity, going from around 1.5 fortitude all the way up to 10. In order of weakest to strongest, and from this fortitude level comes their threat ranking, Yoju (1.5 Fortitude - 4 Fortitude), Honju (4+ Fortitude - 7.9 Fortitude), and Daikaiju (8+ Fortitude. Daikaiju can also be Honju and lead around their own pack of Yoju). That being said, a singular Yoju can easily be killed by a Defense Force Trainee (10% Combat Power Average). Identified Kaiju are Daikaiju that are extremely powerful and have a fortitude level of 9.0 or higher. Even if their fortitude level is lower than 9.0, if there is a need for identification than a codename will be given. While Daikaiju of this caliber have always appeared in history, their identification numbers were implemented only after the fortitude observation system was established. For example, if a Daikaiju were to appear it would be given a number for identification, as an example the number is 16, it would simply be called Kaiju No. 16 (Kaiju Number 16). Intelligent Kaiju also do not give themselves names, usually only referring to themself by what others call them. (Kaiju No. 9 did not give himself a name, rather sticking to Number 9 as his internet name.). Size also matters for threat level, the bigger kaiju usually being more likely to be a higher fortitude (Yoju are smaller, human sized. Honju are Giant, around the size of a building but they can be even bigger, around the size of a whole town. Daikaiju are smaller and can be human sized but can also be as big as a Honju). Kaiju are a symbol of fear, a single kaiju in an area is enough to scare off people into shelters while waiting for the Defense Force to arrive. Kaiju are also put into priority when they appear, if its a singular Yoju, a single soldier will be sent out, a small squadron (around a dozen soldiers) will be sent out for a Honju or an entire division if the Honju is bigger, Daikaiju will have an entire division attack it if its large, and if its smaller, a vice-captain or a captain will fight it. Notable Abilities for Kaiju: Physical Capabilities, Pseudo-Foresight, Shapeshifting, Sonic Attacks, Energy Emission, Flight, Cyrokinesis, Kaiju Detection, Gigantification, Regeneration, Self-Limb Detachment, Metamorphosis, Memory Assimilation, Fusion, Duplication, Kaiju Resurrection, Kaiju Creation, Kaiju-kinesis (Control of Kaiju corpses), Forcefields, Radio Signal Interference, Kaiju Control Pheromones (Remote control of Kaiju by scent.), Projectiles, Muscle Enlargement, Hydrokinesis, Blade Creation, Passive Adaptation, Levitation, Teleportation, Portal Manifestation, Psychological Manipulation, Telepathy, Memory Induction, Mental Control, Parasitic Nature, Induced Metamorphosis, Psychological Influence. Threat Level Rarity: Yoju (Extremely common, but can be found around a Honju), Honju (Rare but not hard to find, exceptionally large Honju are rarer however.), Daikaiju (Practically impossible to find but they can appear, only been 7 in history before Kaiju No. 8 (Kafka Hibino, Main Protagonist) and Kaiju No. 9 appeared.)

The corpses of Identified Kaiju are turned into particularly powerful weapons known as Numbers. Provided by Izumo Tech, these weapons are battlesuits which keep the abilities and strength of a kaiju when it was alive and are strong enough to seriously damage or kill Daikaiju-class monsters; however the user must be compatible with them to use them properly.

The combat suit used by members of the Defense Force is a bioweapon made of kaiju cells and muscle fibers. Depending on the Unleashed Combat Power of every user (0% to 100%), it accordingly augments the wearer's physical attributes like strength, speed, precision, and reflexes. An unleashed combat power of 40% or higher is stated to be Platoon Leader level. According to a Vice-captain in the manga, an unleashed combat power of 84% is high enough to attain the rank of captain anywhere in the Defense Force. Abuse or extended use of the combat suit's power can cause overheat, injuring its wearer and causing physical pain to the point of making them bleed due to exhaustion. To overcome this limit, a Numbered suit made from a Daikaiju would be needed. Due to them being the strongest combatants within their division, the Captains and Vice-Captains are given customized weapons to suit their personal fighting styles. A Platoon Leader or an officer with exceptional combat skills may also be given a personal weapon. The Defense Force is divided in Divisions, large military groups who engage in kaiju killing missions all over their stabilized area. Each division has its own Captain and Vice-Captain, along with many platoons led by a remarkably powerful soldier. Division operations are guided by the aid of Operations Leaders, who assess the situation from data and computers and announce kaijus' arrivals, fortitude, threat ranking, weaknesses, and deaths. The Defense Force may use guns with specialized bullets, personal weapons, numbered weapons, etc.
