The people of the alpha plane have made it their hobby to enter the dungeons of other worlds and conquer them. Naturally not everyone is happy with this as dark undercurrents begin to work against the conquerors.

As some people die in the dungeons they are made an offer. To give up their humanity in order to live on. 
Guy, a veteran carrier, is one of them, he can't bear to leave his family alone and accepts. From then on he must fight in the dungeons but as a monster while simultaneously continuing his life in the alpha plane in the shape of a human.
Jade, an elite adventurer, also accepts the offer but her intent is solely to get revenge on those who killed her and make humanity suffer for her life.
Monica, a little girl not native to the alpha plane is pulled into the happenings due to her childish innocence.

Counter Dungeon-Delving

But I am the one doing everything! She's just hiding!


<Technically, she is letting you do everything. She's still in control and simply chooses not to exercise it.>


What now? Can I go back to killing things?


<No, previously you killed a lot of monsters inside the dungeon called dragon nest. Killing monsters affiliated to a dungeon is forbidden unless you are specifically authorized to do so. The only reason you got away with it, is that Jade did the dungeon a large service before she had her… accident. In consideration of that contribution, the dungeon allowed you to wreak havoc. It also helped that you brutalized any adventurers you met.>


<Sentient, humanoid creatures not affiliated with the dungeon. They come in groups and use equipment.>


Ah, the pests. Yeah, I got rid of those whenever I saw them. Was that good?


Can I just go back to the dungeon then?


<Unfortunately, no. Jade had a… client, Kent Bloodborne, whom she was helping to level up his sanguine boost skill. She's been gone for a while and he insists on seeing her.>


Bloodborne… that name makes every fiber of my being want to go on a killing spree. The other one stirs and I feel that darned boost activate without my consent. Stop that!


I'm trying, but the other one is interfering! I force down the urge to kill something, anything, and suppress that horrid skill with everything I have. Finally I succeed and the other one calms down enough for me to stop the skill.


The dreams! Those horrible dreams where something controls my body and kills everything…


I do, but that's not me! It's also not the other one. It feels uncomfortable!


<Well, it's necessary for your skill to level up. Wait, when is the last time you slept?>


I don't care! That dream is way worse! And I repeats every night!


<That's because you keep losing! If you win the last fight, the skill will level up and you'll be free from that dream until your skill can level up again!>


Really? If I let the dream finish I get to sleep in peace?


Hmm, I never let it get that far before breaking out of the dream. I guess I'll try. Do you know what I'll be fighting at the end?


<That's all we have to go on. But it fits most things Jade witnessed. It's color should be crimson, there was lava flowing from its mouth, Jade mentioned that the sun's heat was especially noticeable and it went berserk after getting hurt. Also, bears hibernate so that would fit the mention of slumber.>


So you think the opponent I'll face will be different?


I guess. Then, what are my possible opponents?


<We've found two other mentions of creatures associated with red beside the one I told you about and the one we believe to be your ancestor. One is a sailor's account of a creature flashing red lights at them in the sea. He was the only survivor and the tale is generally believed to be an old kraken sighting. However, the description doesn't match a kraken. It allegedly used flashing red lights to lure the sailors of course, even prompting some to jump into the water. Then, it climbed onto the ship and attacked the remaining sailors. The account is very insistent that its attacks always hit their targets despite appearing quite slow.>


Some kind of sea horror? An attack that always hits, sounds like a pain to deal with.


<That's one, the other is a tree. Legends describe it as a demonic tree that has one red leaf. Any who approached the tree died mysteriously. The symptoms that were described match those of a serious allergic reaction. Allegedly, a living god descended in those times and the entire tree was felled. All the leaves slowly withered but the red one was never found.>


What is this, a creepy horror story collection? Living god, pah, who'd believe that?
