A Class that's fueled by the blood of his enemies and human sacrifice. One that's illegal to use, punishable by gruesome death.

I somehow managed to be reincarnated as a maid who monopolized the Emperor’s affection. In the end, she was killed by the Evil Empress through vicious means.‘Fortunately, I’m only five years old.’‘I still have a long way to go before the original work begins, so shouldn’t I just avoid the Emperor and Empress until then?’I thought so, but…“Lize, what did you say to the Emperor?”“I said that I support you.”The evil Empress who was supposed to kill me in the original story won’t leave me alone.“Truthfully, you like me much more than the Emperor, don’t you?

WRONG!Before he could even process his isekai moment, he found himself being chased by a horde of horny male orcs.From dodging unwanted “affections”, to getting thrown in jail, to accidentally sleeping in horse crap and earning just enough to not starve. Between dealing with an ex-adventurer boss, getting tricked by his so-called “friends,” and realizing even slimes are harder to kill than he thought, his life in this new world is anything but the overpowered adventure he dreamed of. Instead of becoming a hero, he’s stuck as a low-wage wall repairman, constantly broke, and now the locals call him “Shitman.”With zero cheat skills, no legendary weapons, and a severe lack of dignity, Hazekaya is left wondering—“Why is my isekai life like this!?”
