How Rerolling Works in KAIJU NO. 8 THE GAME

Rerolling is the process of restarting your account until you summon the characters you want from the gacha system. Since initial summons can determine how quickly you progress, rerolling helps you optimize your team from the very beginning.

Steps to Reroll

  1. Download and Install the Game on MuMuPlayer – Use the Synchronizer for managing multiple accounts at once!
  1. Complete the Tutorial – Progress through the initial missions until the game allows you to perform free summons.
  2. Use Initial Gacha Summons – Perform the free rolls granted at the start.
  3. Check Your Results – If you get the desired high-tier characters, bind your account to keep progress safe.
  4. Reset if Needed – If not satisfied, reset the game data and repeat the steps.

Tip: Guest accounts make rerolling faster, while binding ensures that once you secure good pulls, you don't lose them.

Best Characters to Target During Reroll

When rerolling, focus on high-damage attackers or versatile characters that provide both offense and utility. According to the early character rankings:

  • Kafka Hibino (Kaiju Form) – Strong attacker with explosive damage output.
  • Mina Ashiro – Long-range DPS with consistent high damage.
  • Kikoru Shinomiya – Balanced fighter with strong skills and survivability.

These units can carry you through early game content more smoothly and remain useful later on.

Rerolling Tips for Efficiency

Save Time with Guest Accounts

Guest logins are the fastest way to perform multiple rerolls. Since you don't need to bind an account at first, you can quickly reset progress if you're not satisfied with your pulls. Once you obtain your desired unit, immediately link the account to prevent data loss. This approach ensures both speed and safety.

Prioritize Multi-Target Damage

Early missions often feature waves of enemies. Characters with wide-area attacks or strong burst damage can clear these stages quickly, giving you an immediate advantage. Securing a top-tier AoE attacker during rerolls will make farming resources and progressing through chapters much more efficient.

Consider Future Investment

Some characters are powerful even at lower ascension levels, while others scale better once upgraded. When rerolling, aim for units that remain useful in both early and late stages, ensuring your efforts don't go to waste as the game progresses.

Don't Chase Perfection

While damage output is critical, it's also important not to overlook survivability. A strong defender or versatile fighter can prevent your team from being overwhelmed in harder stages. If you reroll into a combination of one high-damage unit and one reliable defender, it sets up a balanced foundation.
