About Kaizen Online
A dream, a passion, a community.
Kaizen Online is more than just a Minecraft server—it's the result of a dream that started in October 2023. Inspired by the world of Jujutsu Kaisen and a love for MMORPGs, I set out to create something unique: a server where players could experience epic battles, custom powers, and a real sense of progression.

Since day one, I've poured my heart, my time, and honestly, a lot of money (des tales de bz) into this project. From late-night coding sessions to endless testing, every detail has been crafted with passion. The goal? To bring together a community of players who share the same excitement for adventure, challenge, and anime vibes.

🧑‍💻 One-Man Project: Kaizen Online is mainly developed and managed by Saafuu, with occasional help from a few partners. This is not a big company or a large dev team—please be patient and understanding! Today, in 2025, Kaizen Online is still evolving. The server has grown, new features keep coming, and the community is more alive than ever. None of this would have been possible without the support, feedback, and energy of everyone who joined the journey.
October 2023: The idea is born. First lines of code, first dreams of a Jujutsu Kaisen MMORPG in Minecraft.
2024: Countless hours of development, custom plugins, and the first beta testers join the adventure.
2025: Kaizen Online becomes a real community. New features, events, and a growing playerbase.
"No matter how big the dream, with enough passion and a bit of madness, you can make it real.
Thank you to everyone who believed in Kaizen Online. The adventure is just beginning."
