“You don’t need divine blood to burn the world down. A mortal’s flame does the job just fine.” Meet Minato. He was the last surviving master of an ancient clan known for its deadly martial arts and weapon-making skills. Now? He’s just a guy who woke up in the blood-soaked, cannibalistic streets of the Tokyo Ghoul universe. No magic. No overpowered cheat system. No bullshit bloodlines. Just his bare hands, lethal tech, and pure human grit. But when he crosses paths with a certain one-eyed girl named Sen Takatsuki (Eto), the rules of the game change. In a city crawling with flesh-eating monsters, Minato is going to show them exactly why humans are the real apex predators. He’s going to bathe in the sins of this broken world and violently carve out his own throne. But Tokyo is just the warmup... Minato is on a one-way warpath across the multiverse to prove a point: Gods can bleed, and he's the guy holding the knife.

Hello everyone, I was reading a few cross over comics that included Batman and Spiderman crossover to Captain America and Transformers crossover to fanfics that included Pokemon and Transformers crossovers. It looked like fun so I decided to write this while I am having a bit of writers block. BTW this will be like a short novel, less than 30 chapters. It will not be a full fledged book. If anyone wants to make these ideas full on books go ahead. Just give me a heads up because I would love to read them too. :D

Through the wall, I saw that gentle, timid white-haired widow actually…!

Sophie Wexler transmigrated into a novel about The Galaxy, becoming the vicious, F-rank Healer-class cannon fodder. The original owner constantly caused trouble and made things difficult for the female lead, earning her the hatred of the entire internet. Upon transmigrating and seeing that everything had been ruined by the original owner, Sophie's only thought was: "What kind of nightmare start is this?!" To escape the original owner's fate, Sophie Wexler worked diligently, conducted herself conscientiously, stayed away from the male and female leads, compensated the soldiers harmed by the original owner, and strove to be a model citizen of The Galaxy, absolutely refusing to be the cannon fodder 'offed' by the Imperial Marshal! Broke and powerless, Sophie also had to support a man who'd been innocently dragged into the original owner's mess. She had no choice but to hustle. She started live streaming, became a masked singer, and held concerts. At first, netizens were scornful: 【Tsk, how good can she possibly sound?】 Later, the netizens were forced to eat their words. 【Damn, that's so good I'm on my knees!】 【What the hell, the violent episode of my Disorder Period has actually been soothed?!】 【The toxins in my Spiritual Sea have actually been eliminated!】 Her live streams went viral, the masked singer became a huge sensation, and tickets for her concerts were snapped up across The Galaxy. Sophie was content, thinking, "This time, I must have finally escaped the original owner's fate, right?" But what do you know, the man I've been doting on and supporting is actually the Imperial Marshal?! --- One day, Yancey Forrest came home to find that the boisterous person who was always claiming to be good to him was gone. His eyes darkened. Provoke me and then think you can leave? After catching her, Yancey traced his fingertips along Sophie's neck, smiling gently. "Why run?" Sophie trembled. "You... you're the Imperial Marshal?" His identity exposed, Yancey Forrest took her hand and slowly placed it on his own neck ring. "You know I won't kill you, don't you?"
