Why Does Deku Go Berserker Mode?

It was the tenth year of the Mechanical Civilization. My girlfriend, who always spoiled her brother to an unreasonable extent, orchestrated my death. Luckily, I was reborn seven days before the arrival of the machines. I bought a heavy-duty truck and evolved the strongest mecha. Close-combat mecha, long-range mecha, weapons, shields, funnels, modules… This time, I wanted the best of everything. My name is Victor Wild. Born to be a victor, born to be wild.

~ Ducan : Demon king ~ My kingdom is on the verge of distraction and my race is about to perish in a blink of an eye. What I need is a blessed maiden who can only be found once per hundred years. A virgin girl with the favour of the gods, who will open her legs for me In order to restore the power slipping away from me. To balance my kindom and the reels of hell, I need her to carry my seed so I could secure my position and forever rule my kind. Once my eyes are set on her, she will become mine with or without her approval, affections or consent.

I always thought my husband, Ryder, was forced to marry me. For six months, he wouldn't touch me. I tried everything. I wore my sexiest lingerie. I guided his hands over my burning skin. I could feel how hard he was, completely out of control. But at the last second, he'd always push me away, gasping. He'd finish me with his fingers instead. My hope died. I decided to leave him. I was ready to accept a top dog trainer position in Europe. The night before I planned to hand him the divorce papers, I heard voices from his study. Ryder, talking to his best friends. "Ryder, you're dying for her, man. So why won't you touch her? Another man's going to snatch her up!" "But she's so fragile..." Ryder's deep voice was filled with pain. "You know... I'm a monster. If she sees what I really am... it will terrify her." His voice dropped to a raw whisper. "If she really needs... comfort... from another man... I can take it. As long as she comes home to me in the end." His friend growled. "Stop! Then maybe stop posting on that encrypted dark web forum, asking for help!" Monster? What did that mean? Late that night, I used his computer. I found a hidden forum called "The Den." A pinned post at the top. Thousands of replies. User ID: Midnight_Howler. One sentence. Dripping with desperation and frantic obsession: "I finally married the girl I've loved for years, but I'm terrified to touch her. How can I survive my rut without hurting her, without her discovering my secret?"

He died killing the Demon King. He woke up sixty years too early. Now the monster is a young man. And he is running out of reasons to stay away. --- Lysan Dusk was the hero who saved humanity. He killed the Demon King, ended the war, and delivered the world from suffering, and his reward was betrayal. He wakes up in a young student's body in a dormitory room of a magical academy, and the calender shows that the date sixty years before he was born. The world outside hasn't broken yet. The war hasn't happened. Lysan's plan is to keep it that way by staying completely out of it. Fail his combat exams, spend whatever borrowed time he has left, living a quiet life, where nothing requires him to be a hero. The man who will become the Demon King, the most feared monster in history is still young and beautiful, with pale grey eyes that find Lysan across every crowded room like he is the only person worth seeing. Lysan knows what those eyes will become. He has looked into them across battlefields, spent a lifetime seeing them in nightmares. He never expected it to feel like this up close. Roman is everything Lysan was warned about — magnetic, dangerous, impossible to ignore. Everyone except Lysan, refuses to be charmed, refuses to feel anything at all. But now, he is failing spectacularly at them because Roman keeps finding him. Keeps watching him and making Lysan's carefully rebuilt walls feel like paper. Lysan knows the ending. But for the first time in two lifetimes, he is wondering if the ending can change. If the monster can be loved instead of killed. If staying is braver than running.

It was the climactic moment of my game, but the enemy's flash bang blinded me. After I reopened my eyes, I found myself in the world of the post-apocalyptic underdog comeback story I'd ranted about to my friend the day before. No, I wasn't the protagonist with a cheat for a system. Instead, I was the cannon fodder who suffered the worst fate. He also had my name. I found myself locked outside the armored vehicle while a swarm of high-level zombies had surrounded me. 'Blast,' I thought. 'All this just because I flamed them? And I just made a pentakill after my 8-win streak!' I told myself to calm down and let my mind do its work, but then the laughter of this body's wife echoed from the walkie-talkie. "Stop covering for him, gunners! We're livestreaming to the whole camp. My husband's going to rip these Tier Six zombies to shreds!" Then, the woman's useless male best friend buzzed with excitement. "I'll have a permanent spot in the inner city if he distracts the horde and they rip him apart in the process, babe!" If this went the way of the original story, I'd beg for help only to get no answer and be ripped apart by the zombies. Fortunately, I wasn't the same coward this guy used to be. The woman kept egging me on. I sneered. I didn't spend years playing competitive games for nothing. And so, I grabbed a high-frequency concussion grenade that could get the attention of every single zombie in a 3-mile radius, smashed the ventilation valve of the armored vehicle, and hurled the grenade inside.
