Prerequisites for Getting KANEKI CENTIPEDE in SAKURA STAND
Thinking you can easily get KANEKI CENTIPEDE in SAKURA STAND just by having Base Kaneki is a complete mistake, especially since losing the battle against Rize is certain without proper preparation. You must focus on managing Hate and collecting Blood Stones, as this is a deciding factor for your success.

What Missions Do We Need to Do to Get KANEKI CENTIPEDE in SAKURA STAND?
As I mentioned before, getting KANEKI CENTIPEDE requires completing challenging missions. Below, we've listed these missions and how to do them for you:
Win direct battles: You must achieve at least 10 wins in 1v1 mode using the Kaneki character.
Eliminate enemies with a specific skill: Killing 5 other players using the B Skill is mandatory.
Collect biological material: You need to collect 100 RC Cells or 20 Meat. You can get these from specs like Vampire, Dracula, or Kaneki himself.
Industrial construction: You must craft 10 Kakuja Point Concrete. This item is made by combining 3 Premium Concrete (obtained from Cyber Boxes).
Deal heavy damage: You must deal a total of 5000 Damage to enemies with Kaneki.
Manage the health bar: You must let your Heal Bar drain 5 times by the Hate mechanism.
Craft metal parts: Produce 10 Kakuja Scrap Metal, made by combining 3 Alloy Steel (dropped from Podgy).

The Final Battle with Rize
After completing all the stages above, it's time for the final fight against Rize to get KANEKI CENTIPEDE in SAKURA STAND by defeating her. But before entering the battle, you must do one thing: buy the Higanbana Flower for 500 Blood Stones from the Halloween Shop. Another point to remember is that to complete the prerequisites for getting KANEKI CENTIPEDE, you must land the final blow with KANEKI himself. If you don't do this, you cannot get the V2 version.
Final Step to Activate KANEKI CENTIPEDE
After you manage to defeat the boss, you must talk to the Best Friend in the arena environment again. Here, you need to activate a special mechanism: you must die in battle when your Hate level is above 90%. This finally activates Kaneki's hidden potential, and you can obtain KANEKI CENTIPEDE in SAKURA STAND.
Important Tips to Consider
Many of the items used on this path require high precision in crafting.
Using Cyber Boxes has a variable chance of giving basic materials, so it is recommended to always save some extra Blood Stones for emergencies.
Try to do the 1v1 battles during off-peak server hours when you have less lag.
