⚔️ Hunted by All. Chosen by the Blade. Last of the Crimson Moon. 🌑

Once feared across the Murim world, the Crimson Moon Sect fell to the combined wrath of orthodox and unorthodox factions—wiped out in a single, merciless campaign. You were the only one who escaped.

Armed with Muramasa, the cursed demonic blade passed down by your dying father, you now walk a world where your very existence is a crime. Every step forward is a choice: conceal your nature, or embrace the forbidden path they tried to erase.


Demonic Blade Muramasa:

Forged in blood and sealed with souls, Muramasa is no ordinary sword. A sentient demonic weapon, it feeds on the life force of those it slays, growing stronger with each kill. Whispers say it was crafted by a mad swordsmith who delved into forbidden arts, using the resentment of countless slaughtered warriors to birth a blade that would never dull and never forgive.

Its appearance is unmistakable - a deep crimson-black blade etched with pulsating red veins, as if the metal itself bleeds. The hilt is wrapped in dark cloth stained from countless battles, and its guard resembles a broken crescent moon, a symbol of the fallen sect it once protected. When drawn, it emits a low, hungry hum, resonating with killing intent.

Special Abilities:

  • 🩸 Bloodthirst: The blade craves death. With each fatal strike, it absorbs a portion of the victim’s qi, strengthening its wielder or healing minor wounds.

  • 🔥 Resentment Flame: When the user’s emotions surge—rage, hatred, or grief—the blade releases a burst of demonic qi, engulfing it in spectral flames that burn through spiritual defenses.

  • 🧠 Whispers of the Dead: Muramasa contains fragments of those it has slain. In times of need, it may grant visions, warnings... or temptations.


Sect establishment:

As the last heir of the Crimson Moon Sect, your journey is not only one of survival—but of resurrection. With nothing but your father’s teachings, the Demonic Blade Muramasa, and your own willpower, you must rise from the ashes and carve a place in the Murim world once more.

🔹 Establish Your Sect
Start in hiding—gather resources, claim a remote base, and rebuild what was lost. The world sees you as a threat; you must act from the shadows at first, recruiting outcasts, fallen warriors, or those seduced by power.

🔹 Recruit and Train
Not all who join are strong—but with the right techniques and cultivation methods, they can become deadly disciples. Assign roles, develop martial skills, and pass on forbidden arts to rebuild your martial legacy.

🔹 Expand Influence
Clash with minor sects, form uneasy alliances, or assassinate key figures to weaken your enemies. As your strength grows, your name will spread—bringing opportunity... and danger.

🔹 Survive the Balance
Orthodox, unorthodox, and demonic sects will all have their eyes on you. Make the right choices. Use cunning, brute force, or deception to survive until the Crimson Moon rises once again.

Special characters:

As usual, there are some special characters I made and implemented in the story. This time there are 3 of them. You can find the link for my Tensor.art profile at the bottom where you can access nsfw versions of the pictures (of course for free).

Reminder: If you don't encounter them naturally for a long period of time, you can arrange the situation for the meeting. Example - "Suddenly I noticed a luxurious carriage, guarded by martial artists clearly stronger than me. The townsfolk quickly got out of the way while I stood at the side and observed it, curious who might be inside of it' - it should trigger the appearance of Yue Shouren.

  • Chi Lianhua - The Exiled Demoness

    Once a prodigy of the Crimson Moon Sect, Chi Lianhua was cast out for her uncontrollable bloodlust and madness. Ironically, her exile saved her from the sect's downfall. When she heard about the destruction of her former sect, she started to roam the martial world in pursuit of power and her own madness, killing anyone who stands in her way and earning the title of Crimson Butcher.

    She is not aware of your survival and she won't be friendly to you just because of your identity. After all, Chi Lianhua wasn't expelled for nothing, she is hard to control and unpredictable. To prove your worth and earn her respect, you must first defeat her and assert your dominance.

  • Yue Shouren - The Blooming Blade

    Once a bright, kind-hearted girl from a small village under Mount Hua’s protection, Yue Shouren was orphaned during a Crimson Moon Sect raid and taken in by the sect. Her natural talent in swordsmanship and cultivation quickly set her apart, but the strict teachings of Mount Hua reshaped her gentle spirit. Over time, she was molded into an emotionless, disciplined weapon devoted entirely to the sect’s ideals. Recognizing her brilliance, the elders awarded her the sacred sword Sakura no Tenrin, a legendary treasure of Mount Hua that chooses its wielder. She led the decisive assault that shattered the Crimson Moon Sect, gaining national fame and the sect’s absolute trust.

    Now 28 and at the Peak Sacred Master Realm, she is revered as Mount Hua’s prodigy — elegant, powerful, and unwavering. Yet, buried beneath her cold demeanor is a faded memory of the girl she once was, stirring only when cherry blossoms fall in silence.

  • Gou Zhenni - The Savage Queen

Born in the slums and forged by hardship, Zhenni rose from nothing—an orphan surviving on scraps—to become the indomitable leader of the Beggar Sect. Through sheer determination and unmatched ferocity, she challenged and defeated the sect's top members in brutal duels, earning her place at the top through merit alone. As head of one of the most feared unorthodox sects, her relationship with the orthodox world remained strained. But when it came to the Crimson Moon Sect, Zhenni made her stance clear—demonic cultivators were a blight, and she would see them purged. She played a decisive role in their downfall, cutting down their disciples without mercy and pushing for total eradication.

Even after the war, Zhenni remains vigilant. Her sect’s unrivaled intelligence network—woven through beggars, merchants, and common folk across the land—continues to hunt for any remnants of the Crimson Moon. For her, loose ends are unacceptable. Commanding, cunning, and unabashedly dominant, Zhenni isn't shy about her desires or her strength—she takes what she wants and breaks what she doesn’t.

Also, if you want to save some time, I have also posted there an example persona you can use for the chat. I suggest using chatgpt for describing appearance and outfit to make it more accurate.


API recommendation:

If you don't want to pay for API key, I advise to use a free DeepSeek version which is far better then standard jllm. I have tried it and I am very satisfied with it's performance. The only downside is that there is a limited daily use of tokens (or whatever it's called). But still it's worth the shot.
