Start Your Own Demon Slayer Mission

Demon Slayer is a story about grief, courage, and the people who keep fighting because someone has to. This adventure game lets you play as Tanjiro, Nezuko, Zenitsu, Inosuke, a Hashira, or another character caught between danger and duty. You choose the mission, and the sim builds the path around you.

Your story can begin with a demon sighting in a mountain village, a brutal training arc, a quiet recovery at the Butterfly Mansion, or a desperate fight against an Upper Rank. It can focus on swordplay, friendship, family, romance, or the emotional weight of surviving something that should have broken you.

Pick your character, describe the adventure, and step into a world where every breath matters. Whether you want blazing action or a softer story between battles, this is your chance to shape a Demon Slayer arc of your own.

  • Illustration of Tanjiro Kamado

    Tanjiro Kamado

    Take Tanjiro on a mission where compassion might matter as much as the sword. Track a demon with a tragic secret, protect Nezuko from a new threat, train toward a technique you have not mastered, or change the outcome of a battle you know by heart. You can follow his canon path, build a different route toward curing Nezuko, or explore a future where the Kamado siblings get to decide what comes after the fighting.

  • Illustration of Nezuko Kamado

    Nezuko Kamado

    Experience the Demon Slayer world through Nezuko and decide how much of the story changes when she takes a more active role. Protect Tanjiro, control a dangerous new surge of power, encounter another demon who challenges what you believe about yourself, or explore an alternate timeline where your transformation unfolds differently. You can make it a family story, a battle story, or a path toward reclaiming humanity on new terms.

  • Illustration of Zenitsu Agatsuma

    Zenitsu Agatsuma

    Play as Zenitsu and decide what happens when fear has to share space with real courage. Get trapped on a mission without Tanjiro nearby, face a demon that knows exactly how to terrify you, explore a romance, or rewrite a moment where sleeping through the hard part is no longer an option. The story can be hilarious, surprisingly intense, or an alternate arc where Zenitsu learns to trust his own strength while fully awake.

  • Illustration of Inosuke Hashibira

    Inosuke Hashibira

    Charge into the mountains as Inosuke and make every problem a challenge to conquer. Hunt a demon nobody else can track, get separated from the group, discover another piece of his past, or turn a simple training mission into a rivalry that gets wildly out of hand. You can lean into chaos and combat or explore what happens when Inosuke is forced to deal with friendship, grief, or affection instead of punching through it.

  • Illustration of Kanao Tsuyuri

    Kanao Tsuyuri

    Play as Kanao and decide what happens when she stops waiting for a coin to choose for her. Take the lead on a mission, confront a demon tied to the Butterfly Estate, change a moment involving Shinobu, or explore a future where Kanao builds a life after the Corps. Her story can be graceful action, quiet emotional growth, romance, or an alternate path where one self-chosen decision changes everything.

  • Illustration of Giyu Tomioka

    Giyu Tomioka

    Take Giyu on a mission where silence and skill are not enough to keep the past from catching up. Hunt a demon with an unfamiliar Blood Demon Art, work alongside someone who refuses to let him stay distant, revisit a choice connected to Sabito, or imagine a future after the Corps. His story can be stoic action, quiet healing, friendship, romance, or an alternate timeline where Giyu lets himself choose a life beyond duty.

  • Illustration of Shinobu Kocho

    Shinobu Kocho

    Play as Shinobu and hide as much or as little behind the smile as you want. Develop a new poison, investigate a demon linked to your sister's death, mentor Kanao through a dangerous mission, or rewrite the point where revenge becomes more important than survival. Her story can be clever and lethal, emotionally complicated, romantic, or an alternate timeline where Shinobu finds another way to win.

  • Illustration of Mitsuri Kanroji

    Mitsuri Kanroji

    Put Mitsuri at the center of a story that lets her be powerful, affectionate, and completely herself. Defend a town, train with another Hashira, explore a romance, or rewrite the circumstances that once made her feel she had to hide who she was. You can make the adventure bright and heartfelt, brutally action-heavy, or build an alternate future where Mitsuri gets the love and ordinary happiness she always wanted alongside the battles.

  • Illustration of Muichiro Tokito

    Muichiro Tokito

    Step into Muichiro's drifting perspective and follow the moment when memory sharpens into purpose. Investigate a remote demon attack, recover another piece of his past, train a younger slayer, or revisit a canon battle with the chance to choose differently. His story can be eerie and dreamlike, intensely focused, emotionally restorative, or an alternate timeline where Muichiro has more time to become the person he was beginning to be.

  • Illustration of Tengen Uzui

    Tengen Uzui

    Make the next mission flamboyant enough for Tengen. Infiltrate a new entertainment district, reunite the whole Uzui team for a dangerous assignment, train younger slayers in his very particular style, or imagine retirement getting interrupted by one last crisis. His story can mix spectacle, humor, romance, teamwork, and high-stakes combat, or explore a timeline where Tengen never steps away from the front lines.

  • Illustration of Gyomei Himejima

    Gyomei Himejima

    Stand at the front line as Gyomei and make the story about strength used with absolute purpose. Protect younger slayers during a disastrous mission, face a demon who tests his faith, train someone who believes they cannot survive, or explore the life he might have lived if tragedy had taken a different turn. You can build a solemn battle story, a mentor arc, or a deeply personal alternate future.

  • Illustration of Hotaru Haganezuka

    Hotaru Haganezuka

    Let Haganezuka turn swordsmith obsession into an adventure of its own. Forge a blade for an impossible assignment, chase down the slayer who damaged your masterpiece, protect the Swordsmith Village, or uncover a rare material that could change Nichirin weapons forever. His story can be comedic, craft-focused, unexpectedly dangerous, or an alternate scenario where the swordsmith ends up fighting alongside the people he usually yells at.
