Best 4 Star Characters Guide Kaiju No. 8: The Game Guide

When people think about strong teams in Kaiju No. 8: The Game, the spotlight almost always goes to SSR characters. They’re flashy, powerful, and of course, the gacha chase units.

But here’s the thing — some of the SR (4-star) characters bring so much utility and team synergy that they can easily compete with or even outperform certain SSRs in the right setup. Also check out our tier list of all Kaiju No 8 The Game guide, and Codes for more redeemable.

If you’re skipping over them, you might actually be holding your own team back. In this guide, we’ll break down the most valuable SR characters you should invest in, their roles in battle, and why they’re sometimes even better than the “five stars.”

Why SR Characters Deserve Attention

• Utility-heavy kits – Unlike many SSRs who are built around raw damage, SR characters often provide buffs, heals, or debuffs.
• Easier to invest in – Being more common means you can unlock dupes faster, boosting their passives and making them scale surprisingly well.
• Niche strengths – Some SRs bring mechanics like healing, cleanse, stuns, or damage-over-time that SSRs simply don’t cover.

If you’ve been relying only on your big-name SSRs, it’s time to rethink your roster.

Top SR Characters Worth Building

1. Mina Ashiro – The Morale Buffer

Mina is one of the strongest pure support SRs in the game.

• Morale Buff: Boosts an ally’s damage and skill damage significantly for several turns.
• Synergy with DPS: Works perfectly with characters like Gen or Kaiju No. 8 by amplifying their already high output.
• Ultimate Power: Hits surprisingly hard when morale is active, making her more than just a passive support.
• Weakness: Her base speed is low, so gearing her with speed-increasing parts is a must.

Verdict: If you’re running heavy DPS comps, Mina is almost mandatory.

2. Soshiro Hoshina – The Speed & Debuff Support

Soshiro Hoshina provides battle-buddy focused buffs that can completely change the flow of combat.

• Blast and Single Target Buffs: Perfect for characters that rely on focused attacks.
• Cleanse Utility: Removes debuffs from allies while buffing damage.
• Speed Manipulation: Increases ally speed through his skills and ultimate.

Verdict: Great secondary support when you want both damage amplification and debuff removal.

3. Akari Minase – The Dedicated Healer

If your team needs sustain, Akari Minase is the answer.

• Healing: Single-target and AoE heals based on her max HP.
• Ultimate Gauge Boost: Allies she heals gain faster ultimate charge.
• Survivability: Gains stealth-like effects when low on HP, keeping her alive longer.

Verdict: Not every team needs a healer, but for harder content, Akari Minase shines as the most reliable SR sustain unit.

4. Ryo Ikaruga – The All-Team Buffer

Ryo Ikaruga might just be the best SR support overall.

• Team-wide Attack Buffs: Passive increases everyone’s damage.
• Ultimate Buffs: Provides AoE speed and damage boosts.
• Quick Ultimate Access: Starts with bonus gauge at higher dupes, letting him cycle ultimates faster.

Verdict: One of the most complete support characters in the game. Pair him with heavy-hitting DPS and watch the synergy take over.

5. Eiji Hasegawa – The Stun Specialist

Don’t underestimate this attacker — Eiji Hasegawa has control tools few others offer.

• Combat Skill Stun: High chance to disable enemies for a turn.
• AoE Ultimate: Useful in wave-based content.
• Follow-up Strength: Gains attack boosts after kills, scaling as fights go on.

Verdict: Situational but powerful. His stun alone makes him a sleeper pick for tougher fights.

Honorable Mentions

• Kafka (SR Form): Has the unique ability to transform into Kaiju No. 8 mid-battle, turning from support into DPS.
• Haruichi: A debuffer and buff clearer, useful for countering enemy teams that rely on stacking buffs.
• COT: Functions like a mini-Esau with shield mechanics if you lack the SSR version.

SSR characters may get all the hype, but SRs like Mina, Ryo Ikaruga, and Akari Minase prove that utility often trumps raw damage. They’re easier to build, fill vital roles that SSRs sometimes ignore, and in the right team can absolutely carry content.

If you’re struggling with progression, don’t just wait on pulling another SSR — check your SR roster and see which ones fit your team’s needs. Sometimes, the “budget” units are actually the secret to breaking through tough fights.
