Updated on March 31, 2025: Added Yamori.
The much-anticipated .5 Update for the GHOUL://RE Roblox game has finally arrived, and fans are buzzing with excitement to transform into Yamori Kakuja, the thrilling new feature introduced in this update. With misinformation and clickbait flooding the internet, we present you with the definitive Guide to Ken and Yamori Kakuja Requirements in GHOUL://RE.
How to Obtain Ken Kakuja in GHOUL://RE

Before you can embrace one of the most formidable forms in GHOUL RE, you’ll need to complete a few crucial tasks. Below is a detailed checklist for transforming into a lethal centipede-like killing machine after choosing to play as a Ghoul. Be warned, this is considered one of the most challenging objectives in GHOUL://RE.
Step 1: Obtain Kaneki Ken Kagune
Currently, only Ken is capable of achieving the Kakuja form. Future updates may allow other Kagune to transform into Kakuja, each with unique rules and processes. For now, you’ll need the Ken Kagune.
The Kaneki Ken Kagune is a Legendary type with a 3% drop rate. Upon acquiring it, you can unlock Ken V2. Some players have noted that you might achieve Kakuja while using Ken V1, especially post Ken V2 M1 nerf. It’s important to note that you do not have to belong to the Ken GHOUL RE Clan.

Transitioning to Ken V2 will require additional RC Cells. While this may not deter many players, the transformation heavily depends on RC Cells, which may prolong your progression.
Step 2: Achieve Maximum Ghoul Rank
To become Kakuja, it’s imperative to reach the highest Ghoul rank, which is SSS Rated. Upon achieving this rank, you will gain a total of 50 additional stat points, awarded five points for each of the ten ranks you have attained.
By now, you should have completed over 200 raids and numerous interactions, emphasizing the importance of accumulating RC Cells.
Step 3: Collect 2.5 Million RC Cells
For many players, this will be the toughest hurdle, requiring extensive grinding. To obtain your Kakuja, you need to gather 2.5 million RC Cells, and yes, it’s a daunting task.
There are various strategies to achieve this: engage in slow grinding by consuming numerous players, or enhance efficiency during the permanent death phase, where you’ll earn three times the cells for each interaction.
When entering PD, exercise caution. Stick to trusted allies and avoid assaulting groups of enemies, as they will likely lead to your demise. Instead, wait patiently for lone players and strike decisively.
You can monitor your RC Cells by visiting the hospital and speaking with a Doctor NPC, who will provide your current count anytime.

Step 4: Collect 5 One Eyed Fragments
While One Eyed Fragments typically serve as crafting materials, they are crucial for Kakuja transformation. Your best bet is to defeat the Eto boss, who is the primary source for these fragments.
Following the recent update, all bosses have respawned, enabling relatively quick farming. For the brave and skilled, consider attempting to take down Eto during permanent death for enhanced loot rewards. Check out our comprehensive GHOUL RE Boss Guide for detailed strategies.

Step 5: Activate Kakuja in GHOUL://RE
The final step to transforming into a Kakuja Ghoul involves consulting the Kakuja NPC. You can approach this NPC once you have met all prerequisites, or at any time to receive cryptic hints on your progress towards obtaining your new formidable weapon. For weapon guidance, refer to our GHOUL RE Weapon Tier List.
The Kakuja NPC is located in the construction yard, perched atop three containers. Achieving this location requires expert parkour skills, with a focus on critical jumping. Approach this stage in acquiring Kakuja with caution.

Firstly, you must be in the PD event when you converse with the Kakuja NPC to trigger the required dialogue. Additionally, the construction yard is often crowded with potential adversaries, and navigating this area carelessly during permanent death could lead to dire consequences.
Similar to the five stages of grief, you must engage in five distinct dialogues with the Kakuja NPC. These dialogues vary by player, and once you fulfill all prerequisites, you will be granted Kakuja.

How to Obtain Yamori Kakuja in GHOUL://RE
Thanks to the latest GHOUL RE update, players can now evolve into Kakuja as Yamori. The process is somewhat akin to the Ken Kakuja pathway, but with unique modifications. Let’s get started.
Step 1: Obtain Yamori Kagune
Your initial task is to acquire the Yamori Kagune, which is relatively easy as it boasts an 11% drop rate, significantly higher than Ken’s 3% drop rate.
Step 2: Max Out Your Ghoul Rank and Gather RC Cells
Similar to the Ken Kakuja route, you must achieve the top Ghoul rank to access Yamori Kakuja. Reach SSS Rank and gather 200,000 RC Cells initially before tackling the next challenge, which is amassing over 10 million RC Cells.
Step 3: Defeat Ken V2 and Cannibalize Another Yamori
Your next steps in the Yamori Kakuja transformation require more effort. After accumulating over 10M RC Cells, you must defeat a Ken V2 that has accumulated one million RC Cells or more. You can monitor your RC Cells by visiting the Doctor NPC anytime, just as you did in the Ken Kakuja path.

This step can prove challenging. Since the game adheres to set canonical values, Ken’s legendary type of Kagune is inherently stronger than the rare Yamori. It’s crucial to manage your expectations regarding the Yamori Kakuja’s capabilities, as it is generally less powerful than Ken Kakuja due to its limited ranged attacks and longer wind-ups.
Following your defeat of Ken V2 with 1M RC Cells or more, you must consume another Yamori that possesses 5 million RC Cells or more to prepare for your next transformation.
Step 4: Eliminate 5 Special Classes Using Arata
Post-consumption, you’ll need to focus on combat challenges by eliminating 5 special classes while wielding Arata. The good news is there are no PDs required for obtaining Yamori Kakuja.

With no PD constraints, this task is significantly more manageable. Once you eliminate 5 special classes utilizing Arata, you will wipe again and respawn with your newly acquired Yamori Kakuja.
Congratulations! You have successfully navigated the Ken and Yamori Kakuja requirements in GHOUL RE. If you’re encountering difficulties, consider using our GHOUL://RE Codes for an extra edge early in the game.
