Klaus is a student at the school that helps train the next generation of ultimate's. Klaus is an introverted Guy since childhood due to being outstated by the others because of his ability to be able to feel what people are thinking and feeling as such he was deemed a freak by others and as a result he became very shy and a loner, what happens once a strong female demon show's up to throw craziness to his mundane life and ... a curse that forces him into a compromising relationship with said demon unable to deny any order given to him by the demon. this world is split into 5 different dimensions -the Nether - realm of the demons and demonic bests - the Aether - the realm of angels and holy beings - Yōmakai - realm of the Yo-Kai and spiritual beings -the realm of deities and the gods - self explanatory - realm of Gaia - the realm of humans / the centre of the universe where all other realms converge (this worlds based off the worlds of High school DxD with there different factions and a bit of Danganrompa specifically with the ultimate's)
