MTL - Hunter × Hunter: The Seven Deadly Sins - Chapter 606 offended all the pillars

There was a time where I was summoned to a different world. I spent more than a year as a Priestess from a different world. I fulfilled my role and decided to return to my original world. Before leaving, I confessed my feelings to my escort knight. And from there I was heartbroken. After returning to the original world for a year and half, I was summoned again. What? Apparently this time, nobody summoned me. I was sent out to a great extent and have a lost love. I cannot face anyone now! No one knows that I was a former Priestess and I can only quickly return to my original world. Even so, it does not seem to work out very well…

Noah Weaverheart was nothing but a poor boy with zero talent in Magic.Stuck at the Apprentice Magus rank for years, he was bullied and looked down upon by everyone in the academy.His pathetic life met an end at the hands of an arrogant noble, who decided to bury him and go about his day like nothing happened.However, as he drifted in between the space between life and afterlife, a set of notifications appeared before Noah.[Suitable Host Found!][Initializing The Supreme Magus System!][…][ERROR! ERROR! ERROR!]Before he could understand what was going on, he found himself jolted back to life, but the notifications wouldn’t stop flooding his vision.[A bug has been discovered in the system!][Trying to fix bug…][Fixing Bug…][…][ERROR! FIXING FAILED!][ERROR! SYSTEM FALLING APART!][…][ERROR! BUG UNABLE TO BE FIXED!][The system has been corroded by the bug. All parameters broken down. Required EXP for leveling up now fixed, limits on quests completely removed, Penalty on quests disabled.]At first, he thought it was a disaster.Then he realized—this bug wasn’t a curse, but a huge blessing in disguise!With no restrictions holding him back, Noah could now level up endlessly—faster and stronger than anyone alive.From worthless trash to an unstoppable force, he would rise above all… becoming the most powerful magus in existence!But the more he learns about his broken system… he realized the bug might be something far greater, and far more dangerous than he ever imagined.

So here's the pitch: I got reincarnated with Mangekyo Sharingan.Sounds overpowered, right? Instant win button?Except I can barely keep it active for thirty seconds without feeling like my brain's being microwaved. My chakra reserves are pathetic. My combat experience is zero. And the system that gave me these powers took one look at my situation and said “good luck” before fucking off into hibernation.Oh, and the Hero Killer—the guy who murders heroes for not being “worthy”—just decided my mom wasn't good enough. She'll never walk again.I know when he'll strike next. I know where. I've got exactly four weeks to train.Four weeks to go from “can't throw a punch without tripping” to “can survive a fight with a serial killer.”The smart move? Stay out of it. Let the pro heroes handle it.But I'm fifteen, angry, and apparently making life decisions with the wisdom of a shounen protagonist.At least I'm in General Studies. Low expectations.What does being a hero have to do with revenge anyway?

She was an illegitimate daughter in a wealthy family, with a lowly status. By chance, she discovered that her ex-boyfriend had sold her out. In order to hide, she accidentally injured him and fled in a panic. From then on, they were bound by an inextricable bond...
