Time Travel: the Infinite Journey of Ghoul

After a mentally ill patient committed suicide, he was reborn into the world of Tokyo ghouls. Then, the infinite space actually called him? "Conquering the world and becoming the king of the world is just my part-time job. My life only exists to seek interesting things and things." "Well... At the moment when life dies, the desire for death and survival is intertwined, it is really... It makes me want to stop!" "Let me... Let me... Feel something more interesting!" By the protagonist who is suffering from illness. PS1: Do you think this is a brainless harem-covered anime fanfic? Do you think this is a novel that is full of fun, no morals, no limits, and only pretends to be cute and silly? Do you think this is a dark and curious, infinitely bloody, brutal and inhumane killing movement? Oh ho ho smile sinisterly, don't be so naive. PS2: "I don't want to take medicine!" By the protagonist. PS3: Newbies and new books, please ask for everything, recommendation votes, collections, rewards, etc... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
