About
Kimetsunoyaiba Tweaks expands Orca’s Kimetsu no Yaiba mod with multiplayer synchronization and gameplay and visual additions, including synchronizing PlayerAnimator animations across LAN and dedicated servers. Nichirin swords can appear sheathed on a character’s hip or back while stored in their inventory, with configurable placement and support for displaying up to two swords; sword swings can also produce configurable slash effects or particles. The mod adds a meditation menu for checking rank and kill statistics, choosing waypoints to quests or locations, and accessing demon skills. Its quest system has tracks for demon slayers, demons, kakushi, and swordsmiths, though the quests are still in early beta. Demons can build custom Blood Demon Arts by choosing eyes, colors, and particles, then assembling forms from moves; leveling unlocks additional form slots, and Demon Alchemy catalysts unlock more moves. Other additions include enhanced Kasugai crows that can guide players to quest locations, quest familiars such as the Nakime Eye and Orochi for demons, and basic CustomNPC support for Nichirin swords and breathing forms. Breathing-style changes include an animated whip sword for Love Breathing, improved dual wielding for Beast Breathing, and revamped Mist Breathing. With the KnY Worlds addon, the location additions include Swordsmith Village, Final Selection Mountain, and an improved Infinity Castle.

Security
No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.2 latest files: the newest file for each Minecraft version and loader. Both are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of both files, for recent Minecraft versions. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
ChatGPT is named in the images in its files
We have not read its code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
