Team Building Tips & Buddy System Strategy

Always Include a Defender

Every strong squad in KAIJU NO. 8 THE GAME should include at least one defender. Defenders absorb incoming damage, ensuring that high-damage dealers survive long enough to maximize their output. Among them, Akari Minase (4★) stands out because she not only provides a solid defensive line but also has healing abilities, which are extremely rare for defenders. This makes her invaluable for both boss fights and extended battles where sustain is key.

Tip: If Akari is unavailable, other defenders can still help with durability, but you may need to add a supporter for extra survivability.

Supporters Should Provide Buffs

Supporters are not mandatory in every squad, but including one can significantly enhance your team’s efficiency. A good supporter boosts your main attackers, ensuring faster clears and higher consistency.

  • Mina Ashiro: Increases ATK and crit potential, ideal for damage-centric squads.
  • Ryo Ikaruga: Provides versatile buffs and adds utility, making him a flexible pick for many builds.
  • Optimal Strategy: Keep the supporter count to 0–1. Too many supporters can weaken overall DPS, while the right balance ensures both strength and stability.

Buddy System Matters

The Buddy System is a unique mechanic in KAIJU NO. 8 THE GAME. Slot 1 is paired with Slot 2, and Slot 3 is paired with Slot 4, creating partner pairs. Some characters gain special bonuses or synergy effects when deployed together in these buddy slots.

  • Example: Certain attackers deal increased damage if paired with a specific supporter or defender in the linked slot.
  • Strategy Tip: Always check each character’s Buddy compatibility when forming a team. A well-placed Buddy pair can make a noticeable difference in both PvE and boss encounters.
  • Extra Note: Even without special synergy, positioning strong units in the right Buddy slot ensures better resource allocation and balanced performance.
