[Crossover] On the Compatibility of Cosmic Horror with Various Worlds

Official title: The Green Abyss

Written purely for love, free and not contracted

What should you do when you discover you have a witch's bloodline that lets you transmigrate between worlds?

Liscaya: What can I do? Just go with it.

But whenever he transmigrates to another world, the gaze of the evil gods inevitably speeds up the nameless one's corruption of that world, and the evil gods are on the verge of arriving.

Liscaya can only restore the glory of investigators, explore the truth, solve all kinds of bizarre incidents, and stop the coming destruction.

He inevitably meets fellow investigators while transmigrating? There's nothing for it. Liscaya can only put on a textbook investigator performance for the bewildered residents of these other worlds, along with some heartwarming displays of teamwork.

Liscaya: (Hangs an Elder Sign around the other person's neck) You've been powered up. Go get them!

Companion: (Grinning) As you command, Captain!

Give the clueless mortals a taste of a little cosmic horror! Lose 1d3 sanity points!

He is kinder to the good and repays the wicked with evil.

And in the end, when the journey of fate reaches its conclusion, he finds the beginning of his adventure and learns the hidden truth. He discovers knowledge no one else can know, learns to feel, and gains true freedom. At last, he walks into the distance, becoming once more that nothingness where sky and sea meet, returning among the stars and opening his eyes anew. He becomes It.

Worlds visited:

[DC]: A case in the nighttime streets of Gotham! The culprit is actually a cult trying to summon an evil god? See how Liscaya beheads the Joker, tramples the Mi-Go, investigates the secret cult behind it all, and brings Gotham's crisis and tragedy to an end! Let Arkham meet a real Arkhamite!

[Katekyo Hitman Reborn!]: Dino's uncle from out of nowhere! A curse flowing through the family! A Cthulhu-flavored adventure! The drawbacks of traveling through time? The Hounds of Tindalos are watching hungrily! See Liscaya teach a chuunibyou world-ending brat a lesson, change a tragic future, and glimpse the world beyond the Silver Gate!

[Jujutsu Kaisen]: The origin of the cursed spirits turns out to be the evil gods! Curses? Nothing compared to the gaze of the evil gods! A fourth calamity who has mysteriously arrived in this world? No problem! Watch Liscaya bring a confused young man around, restructure the rotten jujutsu world, and smash this damn playground!

And many more worlds! The blurb can't do them justice. Come read the story!

(The blurb and the story are very different. The story is serious in tone, and the plot changes a lot, so it may not match the blurb. The author has no outline and writes whatever comes to mind.)

Please read the warnings before you start. I don't want you to get blindsided.

Warnings:

* The protagonist is a psychotherapist from the Cthulhu Mythos world.

* This is a story about a Call of Cthulhu tabletop RPG protagonist traveling between worlds. The first two chapters contain a lot based on the character sheet background.

* The original male protagonist has one-quarter Chinese ancestry. The story mainly follows his own plot, and he doesn't get much involved in the main plots of the other worlds. Original characters from those worlds also don't get much focus. If you're mainly interested in fanfic plots, please think carefully before clicking in.

* The protagonist is a native of the Cthulhu Mythos world. He doesn't know the plots or the timelines. Everything is arranged by the Dice Goddess.

* No CP (there are some all-protagonist elements, and the protagonist is doted on by other original characters).

* The protagonist is naturally detached, but can put on an act. His opinions are influenced by the people around him and the general mood, so he tends to "go with the flow." If everyone hates "evil," then he hates it too; if everyone loves "justice," then he does too. He is therefore unfriendly toward villains. Please skip if this bothers you.

* The protagonist has many cheat abilities and is basically max-level from the start. Please read with caution if you dislike this.

* The author isn't very clever, so the cases are all quite simple. My apologies.

* Contains dice-based narrative elements.

* Dice-based narrative means the story's development is decided by rolling dice. It's similar to a very simple, house-rule-heavy TRPG, and originated from the "name a price" format on Japanese forums. (TRPGs: Call of Cthulhu, Dungeons & Dragons, Gloomhaven, Sword and Sorcery.)

* This story contains original cosmic-horror gods and creatures! Original cosmic-horror gods and creatures!

* Very slow-paced, eclectic, and rough... The author's writing is long-winded and awful (you can tell just from the blurb).

* Many original interpretations! OOC! OOC! OOC!

* A power fantasy! No logic! A chaotic timeline! Don't scrutinize it! Best not to think too hard while reading.

Theme: Set out on a journey, grow through what you encounter, and search for the truth.
