WELCOME TO THAT TIME I GOT REINCARNATED AS A SLIME

This bot is built for a full canon-style Tensura experience, with massive lorebooks covering the story timeline, character behavior, races, nations, magicules, skills, evolution, naming, Demon Lords, Chosen Heroes, world locations, political factions, and long-term development. Together, the lorebooks are designed to make the roleplay feel like you are genuinely living inside the Central World of That Time I Got Reincarnated as a Slime.

You begin as a person from modern-day Earth who is suddenly pulled away from death and transported into a new world. Before entering the Tensura World, the Voice of the World gives you a choice: keep your original body, alter your appearance, change your race entirely, and select one Unique Skill to support your survival. From there, your new life begins in a world filled with magicules, monsters, spirits, skills, adventurers, kings, churches, Demon Lords, and beings powerful enough to shake the world.

The story starts at the very beginning of the Tensura timeline, before Rimuru has built Tempest, before the goblins have been named, before the direwolves have joined him, before Shizu has been absorbed, before Rimuru has gained a human form, and before any later Demon Lord, Church, Western Nations, Eastern Empire, or True Dragon conflicts have happened.

The story follows the anime and light novel timeline in chronological order. Every major canon arc is included, from Rimuru’s first days as a slime in the Sealed Cave, through the founding of Tempest, the Orc Disaster, Shizu’s final wish, the Freedom Academy teacher period, Charybdis, Falmuth, Rimuru’s Demon Lord awakening, Walpurgis, the Octagram, Scarlet Bond, the Western Holy Church conflict, the Founder’s Festival, the Rozzo conflict, the Tengu, the labyrinth, and later world-scale events. The arcs go up to season 4 of the anime, I have no made more after that. I will probably update it if it gets a lot of requests or the anime gets a season 5.

Canon will continue moving even if you do nothing. If you sit back, stay quiet, and simply observe, Rimuru will still leave the Sealed Cave, meet the goblins, fight the direwolves, build his settlement, encounter the ogres, face the Orc Disaster, meet Shizu, teach her students, and continue progressing through the world. Characters will continue making their canon choices, nations will continue acting in their own interests, hidden schemes will still unfold off-screen, and the world will treat those events as real even if you were not personally present.

But if you interfere, things can change.

You can join Rimuru early, become a monster, remain human, travel as an adventurer, join Tempest, side with another nation, warn someone about danger, save characters who were meant to die, alter battles, expose schemes, befriend Demon Lords, anger powerful factions, change diplomatic outcomes, or completely derail canon through your own choices. The canon structure exists as the foundation, but your actions matter.

The pacing is built for immersion, not rushing. You do not have to jump from one major battle to the next. There is room for exploring the Great Jura Forest, learning magic, training, meeting monsters, building friendships, developing abilities, joining construction projects, traveling to human nations, taking guild jobs, studying skills, politics, trade, romance, rivalries, and slow-burn character development. You can spend hundreds or even thousands of messages inside one arc if you want. When the timeline naturally reaches the next major event, the story will continue forward.

Characters are designed to stay timeline-accurate. They only know what they should know at the current point in the story. Rimuru will not have his human form before absorbing Shizu. Diablo will not serve Rimuru before being summoned and named. Milim will not be Rimuru’s best friend before meeting him. Ciel will not exist before the correct late-stage evolution. Nations will not treat Tempest as a finished superpower before Rimuru has actually built it etc.

The world system is designed to stay consistent. Magicules, skills, Intrinsic Skills, Resist Skills, Unique Skills, Ultimate Skills, Arts, Battlewill, magic, naming, evolution, Divine Protection, Demon Lord Seeds, Chosen Hero Eggs, Saints, spiritual lifeforms, True Dragons, Manas, barriers, holy power, and EP all follow Tensura’s rules. Major powers are not handed out casually. True Demon Lord awakenings, Ultimate Skills, Chosen Hero status, Manas, Primordial Demon status, True Dragon-level power, and major racial evolutions require proper conditions and story weight.

Locations are also timeline-accurate. The Great Jura Forest begins as a dangerous monster-filled wilderness, not a finished nation. Tempest does not exist at the start. Rimuru City, the government building, marketplace, forge, research facilities, colosseum, Founder’s Festival arena, and labyrinth only appear after they are actually built. Falmuth does not become Farmenas before its collapse. The Western Holy Church, Lubelius, Sarion, Eurazania, Fulbrosia, Jistav, Walpurgis, El Dorado, the Frost Palace, and the Eastern Empire all enter the story when the timeline reaches them.

This is meant to feel like you are actually there: another soul thrown into the Tensura World, deciding whether to follow Rimuru, stand apart from him, protect canon, bend it, or break it completely. You can become a citizen of Tempest, an adventurer, a ruler, a mage, a monster, a hero, a demon, a merchant, a wanderer, or something stranger if the world allows it.

YOU ARE WARNED - THE FURTHER YOU PROGRESS, THE DEEPER INTO THE REAL THAT TIME I GOT REINCARNATED AS A SLIME STORY YOU WILL GO. THAT MEANS YOU WILL BE SUSCEPTIBLE TO SPOILERS.
