Needless to say, the 4 hoodlums basically split up and start conquering and raping everywhere.
For the first part of the story, it was smooth and steady generic sailing. Like Arifureta, the MC is in a monster infested canyon and is steadily growing stronger by absorbing monster corpses, rescue cat eared waifu from monsters, and met up with elf waifu. Just before leaving the canyon, our MC runs into a spirit that was watching over him called the "King of the Abyss". Just think of this guy as Hollow Ichigo. Hollow Ichigo gives our MC a crest that allows him to borrow some of his powers. The reason will be made clear later. Our MC and his two waifus leave the monster canyon and our MC feels like he is strong as fuck due to absorbing all of those monsters.
Some time after leaving the canyon one of the four hoodlums decide that he is tired of fucking with human prostitutes and some other unspecified demi-humans and now has his dick hungry for some elves. He sets off to conquer the elven kingdom. When the MC's elf waifu heard about this, the MC and his team sets off to defeat that hoodlum fast. The MC's team ran into destroyed elven villages with a bunch of dead ass elves and our MC finally hits puberty and resolves to not be a beta Japanese male and actually want to go kill the hoodlums. Luckily for our MC, the hoodlum has yet to arrive at the Elven royal capital and they got there fast enough to defend the place. In the fight against the first hoodlum, our MC thought he was hot shit and he was doing ok against the guy. Well, turns out the hoodlum has been fighting without using his cheats. Once the hoodlum turns on his hero mode cheats, our MC gets his ass beat down bad. Cue in Hollow Ichigo, telling the MC that if he allows him to take over the MC's body, then he will kill and save his waifu from the hero. The MC says yes and Hollow Ichigo goes full hollowfication and kills the shit out of the hero and then promptly absorbs the dead ass hero and stealing his hero mode cheat. At this point, Hollow Ichigo is happy as hell because he now has a body to inhabit and escape from the boring abyss with. Furthermore, this body has an awesome cheat that allows him to absorb abilities from corpses. Our elven waifu sees that hollow ichigo is evil and uses a royal elven item to disable the crest on our MC and bring him back to his senses. This is the beginning point where our MC begins to be stupider. He cries about how he will never give into the power of the abyss ever again, while hollow ichigo basically just talks in his head saying "Nah mate, you will end up using my powers again eventually unless you want your waifu NTR'ed by the hoodlums". So the MC sets off to find out how he can remove the crest from his body.
