Synopsis

Do you believe in hell?
Throughout my life, I always did, yet despite that, I've consistently acted as if I didn't. Going from one wrongdoing to another, I always believed that at some point in the future—maybe in my fifties or so—I would turn things around.
I aspired to become a good father, crafting enduring memories for my future offspring to cling to long after I was gone. A good husband for my blonde of a wife to mourn forever. A commendable individual who would be a source of inspiration—in other words, I wanted to become what would be considered by the world and perhaps even gods if they do exist—a good person. However, before I could reach that age, before I could become a good person, before I could earn myself a nice spot in heaven, I died, and the hell that I had long pretended to ignore came into existence, awaiting me.
The pain is excruciating, the burning is intense, yet I can't even let out a scream. I yearn for it to cease, but having been here long enough, boiling in this ocean of flame, I understand very well that it won't.
I know it's futile, yet if there is someone out there—anything, anyone—please save me. If you choose to do so, I will dedicate my existence to what truly matters.


Evil MC (One of their main powers requires the sacrifice of an infant soul to be activated.)
Dungeon Core MC: (Basically, the MC is reincarnated as the entity behind a Dungeon.)
Isekai: The usual stuff: a guy dies, gets sent to hell, then gets reincarnated as something not human.


Heroïc MC (I don't think I even need to explain this one.)
Dungeon Core Story (If you're expecting a story that focuses on randoms fawning over how "unique" and "powerful" the Dungeon administered by the MC is, then this story might / will not be for you.)
