The Death Guardian: Satan's strike

A high school boy, Tetsuia Matagami, is killed in a school shooting and is selected by death to be a defender of the living world, a Death Guardian. A negative effect of this choice is he would never be seen unless when he's needed, he could never love physically, and he must stay in a certain area where a portal to hell is located. Tetsuia wanted to be a hero all his life but the afterlife happened to be his only chance to be one. He agreed to this and soon regrets it. A price he has paid, Tetsuia could never be with the one he loves. He serves death in protecting humanity from the forces of the devil for all eternity.

I borrow elements from Soul Eater and from Dragon Ball Xenoverse series. These elements are used only in respect of storytelling and are subject to criticism under fair use. I only wish to make a fun exciting novel that any one can read and understand. Please support the official release of the intellectual properties listed off earlier by watching the anime Soul Eater in its entirety from any streaming services available and please pick up a copy of Dragon Ball Xenoverse or Dragon Ball Xenoverse 2 wherever available.
