The world changed about 50 years ago when monstrous-like animal's called Animonster's suddenly come into the human world and live in it, some are savage monster's whilst other became guardians and loyal companions of humanity but a small amount of humanity became Tamer's, a profession that reserved for taming one specific monster. No one really knows how or why this is all happening but from that day forth, humanity and Animonsters have coexist in a delicate but fragile balance of peace and harmony. Basically, this is like Pokemon with a pinch of Digimon.

Tamer's: Tamers are awakened people's with far more high density mana and magic than other normal humans, they're also have one specific Animonster that was assigned to them through the process of "Selections". After they've been paired with their own Animonster, they're bound for life, like a partner in different species. Tamer's shared their Animonster's Physical Powers, which enhance the body, like super strength, speed, durability (invulnerability), stamina, and accelerated healing. And Tamer's also shared their Innate Powers, each one have at least one ability such as: Locomotion/Movement: Capabilities like flight, teleportation, super-speed, wall-crawling, or phasing through solid objects. Mental/Psychic Powers: Abilities originating from the mind, including telepathy (mind-reading), telekinesis (moving objects), illusion casting, and mind control. Elemental/Environmental Control: The manipulation of natural elements, such as pyrokinesis (fire), hydrokinesis (water), electrokinesis (electricity), or air manipulation. Extraphysical/Supernatural Powers: Powers that break conventional physical laws, such as invisibility, shape-shifting, time manipulation, and reality warping. Energy Manipulation: Generating, absorbing, or redirecting energy, such as plasma blasts, force fields, or absorbing UV radiation. Absorption/Mimicry: Draining or copying the powers, energy, or traits of others. Biological Manipulation: Manipulating, growing, or altering bone structure, matter, or physical form. Tamer's and their Animonsters also shared one life, meaning that if either one dies, the other dies as well. They're able to communicate with their Animonster other as well as they can communicate with other humans and other Animonsters. Tamer's are like the anchor that bind the Animonsters mind and spirit to the real world, keeping them in check and constantly making sure that other Animonsters are well and good with the help of their partnered Animonster.

Animonster's: Animonster's are animals with monster-like traits, other than their appearance and size, each of them awakened supernatural abilities that they shared with their Tamer. They shared mutual relationship with their Tamer, respecting, caring and trusting them as much as they trust them, but once the Animonsters find themselves in an abusive relationship, they can freely end any connections and relationships with their Tamer whenever they please, it is the one thing they're under privileges to. There 5 types of Animonsters: Standard Animonsters, such as wolves, lions, elephants, etc with a few minor changes to either their appearances or sizes, like extra legs or bigger than a truck for example. Prehistoric Animonsters, such as dinosaurs or any other prehistoric animals like sabertooths tiger, wooly mammoth, giant sloth, etc. Hybrid Animonsters, an Animonster with traits of several other Animonsters, like Liger, a fusion of tiger and lion. Mythical Animonsters, ones that's based on myths, legends and folklores, such as pegasus, griffin, dragon, wyvern, slime, etc. Unknown, the most dangerous and unpredictable type, capable of things beyond imaginations, whilst not necessarily stronger, they are unpredictable, loyal only to their Tamer but only IF they find them suited to be their Tamer first. They're not ordered from weakest to strongest, depending on luck's, skills and abilities, any one of them could defeat the others. Oddly enough, there's no humanoid like animals such as primates. (so no Sun Wukong) Animonster's didn't need to eat but they can if they want to, they healed and sustained themselves by resting within their own realm, like how Tamer's healed themselves by resting in their own home.

Ranks: In this world, Ranks that are not based on status but by strength and powers, achieving more by accomplishing amazing feats like most lives saved, how many Animonster's are fought against and defeated, how many missions are completed and how well others accepted them.
