Story
After an unexpected event the protagonist lost his memories and is now fighting to become the Strongest Tamer in this stange world.
What is a Tamer, you may ask? A Tamer was formerly a human that has evolved into a Kaiju after being infected by primordial spores, gaining the ability to control other Kaiju's by providing Power of Root.
To tame other Kaiju's, the Tamers provide a certain amount of their power to the target of their choice.
To tame an unfamiliar Kaiju you first need to capture it by fighting or persuading it in other ways. Then, to form a bond, the Power of Root needs to be exchanged, this is where the fun part happens. Often accompanied by a lot of bodily fluid exchange or even more extreme measures. Keep in mind that a bond, similar to a relationship, needs to be maintained, so a portion of your Power must be supplied on a regular basis.
