Every time it dies, it respawns as the weakest monster on the lowest floor of the dungeon. Hundreds, maybe thousands, of lives — every one remembered, every death felt. But unlike the other monsters trapped in the endless slaughter beneath an unbeatable hero party, this nameless soul keeps its memories.
And with memory comes something dangerous: the will to escape.
After countless reincarnations, it finds something no monster was ever meant to see — a hidden passage leading upward. To reach it, the soul must climb from the bottom up, mastering new bodies, exploiting glitches in the dungeon's rules, and outsmarting heroes who have never lost. Something in the dungeon wants it to stay. Something in the darkness is watching.
The longer it climbs, the more it begins to question what the dungeon truly is — and what it is becoming.
Drowning in a bathtub should have been the end of the problems, not the beginning of weirder ones. Now the protagonist is stuck in a reality where things refuse to die properly, buildings sprout tentacles, and their new best friend is a talking humanoid husky-girl who swears they grew up together.
Between dodging electric bee swarms and taking advice from a tinfoil-hat guru, the two head back home — wherever that is in this System-shattered world. With Reconstitution at zero and her unwavering loyalty at max, love, memory loss, and the end of reality itself stand between them and finding their way back.
She is a dungeon creature with one job: do bunny things. Eat, hop, and eventually fall prey to larger animals. But every day, adventurers pass through the cave she calls home — and she cannot stop listening to their words. Their magic fascinates her. Their language captivates her.
She is just a bunny, and there is no way a bunny could ever become an adventurer. No matter how many words she knows.
An ancient, dreadfully powerful entity once sealed away to slowly fade into oblivion is revived by a chance encounter — though in a much reduced state. A temple monk on her way home for vacation is distracted into exploring a newly formed Spiritual Nexus by the cuteness of its rabbit monsters, setting off an entirely unexpected chain of events. A kitsune whose death moved a goddess to pity is revived as a reincarnated Nexus Core, a land spirit of endless potential whose life is tied to a crystal sphere that must be carefully guarded.
Thrown together by a twist of luck, these three navigate a complex relationship and build their own rules to live by. But there are those who are not pleased to see the return of this ancient being.

Sentience came quite suddenly to Suri the slime, leaving him with an insatiable hunger and a vague memory of pretty lights and lots of magic.

Being isekai'd into the body of a dragon whose only task is to guard and grow a pile of shiny treasure seemed like a win to Bob. Flight, Might, Bite — and all it cost him was dying? Fair trade. There's even a dungeon core as a bonus to his starting pile of treasure.
Unfortunately, his dungeon sprite is a borderline-psychotic 1,200-year-old pixie from a cultivation world who just missed out on becoming a god. She isn't happy about interning for a lizard. The challenges are endless for a newly hatched dragon: idiots with magic swords looking to take his head, a dungeon to grow, a burning desire to expand his hoard — and the uncomfortable need to become a better person before the next downgrade arrives.

While others train in dungeons, Ciel builds worlds. His strength comes not from battle alone, but from patience, growth, and mastery over something far greater than swords or spells.

A dungeon wakes up with no name, no language, and no idea why the first thing it meets is trying to kill it. Fear from terrified intruders feeds the core — but fear is thin and never lasts.
Then a wounded man is left behind inside its walls, and the dungeon discovers something better: his relief when the pain stops, his slow and grudging gratitude when the room grows warmer and nothing tries to eat him. The guild sends kill teams. The dungeon sends them soup.
Nobody asked for a hospital dungeon. That hasn't stopped it.
Asterion's first life lasted far too long. He learned alien languages, mastered unknown magic, and watched his comrades fall one by one before facing the Dark Lady at the bitter end — only to cast a self-destruction spell intended to finish them both. Yet somehow, he survived.
All he wants is to rest permanently. So why does everything keep happening to him? A new magic academy has built itself atop the first floor of his labyrinth and stolen his legendary relics to power their campus. Students keep tumbling through random wormholes into his lap. And deep in the Abyss, an ancient entity stirs.
Perhaps there is a reason he was revived. For now, Asterion is focused on one goal: building the coziest labyrinth possible.
