11th March 2024: We added new Grand Kaizen codes.

Grand Kaizen is an anime fighting game in Roblox. In it, you run around a detailed map completing quests to level up, unlock a skill tree, and ultimately become stronger, either going down the path of becoming a Jujutsu Sorcerer or a High Grade Curse.

If you want to get new techniques to level up your fighting skills in Grand Kaizen, you can reroll. Luckily, these rerolls are easily earned through codes. Developer, OverBlock, normally posts these codes on its Discord, but if you’re not in the mood to hunt them out, we’ve done all of the hard work for you and compiled this handy list of Grand Kaizen codes so you can get back to fighting and getting stronger as soon as possible.
