#1 Priority: Reno Ichikawa – The Ultimate Reroll Target

Reno Ichikawa is the limited SSR whose banner was released on August 31, 2025, making him the absolute pinnacle of reroll targets. The top reroll target in Kaiju No. 8 is Reno Ichikawa. Beyond his high striker performance, he excels in multiple roles, including inflicting Freeze and restoring SP. Additionally, since he cannot be obtained from the standard THE GAME Gacha, acquiring him through rerolling becomes essential.

What makes Reno exceptional:

Ice Crystal Mechanics: He applies Ice Crystals to enemies, and after other characters in your party deal damage to these enemies, they will take additional damage
Crowd Control Mastery: Spreads Ice Crystals to nearby enemies, creating chain reactions of bonus damage
Team Support: Reduces opponents’ Physical and Elemental RES, amplifying your entire squad’s effectiveness
Limited Availability: Cannot be obtained from standard banners, making early acquisition crucial

Kaiju No. 8: The Powerhouse Protagonist

Kaiju No. 8 is another DPS who can dish out massive damage numbers due to the high base stats and buffs in his kit. This character brings both raw power and unique utility that makes him an excellent alternative to Reno.

Combat Advantages:

Instant Execution: The Combat Skill for this character instantly defeats any small-sized Kaiju that has below 50% HP
Fighting Spirit Stacking: Gains damage buffs by taking hits, turning defensive situations into offensive opportunities
Standard Banner Access: He is a standard banner character, and rerolling for him could be easier, since players get more pulls for this banner

Strategic Team Building Considerations

Gen Narumi: The Versatile Striker

Gen Narumi is another standard banner DPS unit that can wield dual elements, thanks to his kit’s inclusion of the Slash and Shot elements. His versatility makes him invaluable for tackling diverse enemy types and resistance patterns.

Isao Shinomiya: The Shield Master

Isao is primarily a Blunt Defender, who protects nearby teammates by providing them with a shield. He is special, since he is the only SSR unit with Defending skills. This exclusivity makes him extremely valuable for team composition balance.

Mina Ashiro: The Giant Slayer

Mina Ashiro. She is a Shot-type Attacker who deals massive damage numbers through her special skills and specializes in eliminating large-scale threats that other characters struggle against.

Optimal Rerolling Strategy

Priority Hierarchy:

First Choice: Aim for Reno Ichikawa due to his limited availability and unmatched utility
Strong Alternatives: Kaiju No. 8 + Gen Narumi – a strong combination for quick progression
Balanced Approach: Any combination of two SSR characters from the top 5 list

Time Management: Rerolling is useful, but it shouldn’t consume too much time. Ideally, you can stop rerolling once you obtain one of the following high-priority targets.

Frequently Asked Questions

Q: Should I prioritize getting Reno Ichikawa over having multiple SSR characters from the standard banner?

A: Yes, absolutely prioritize Reno Ichikawa if possible. His limited availability means you cannot obtain him from standard gacha pulls after his banner ends, while standard banner characters remain permanently available. Reno’s unique Ice Crystal mechanics and team support capabilities provide more long-term value than having multiple standard SSR characters. However, if you’re spending too much time rerolling, a combination like Kaiju No. 8 + Gen Narumi from the standard banner still provides excellent progression potential.

Q: How many reroll attempts should I make before settling on my starting roster?

A: The optimal approach is to set a reasonable time limit rather than a specific number of attempts. Most experienced players recommend spending no more than 2-3 hours rerolling, as the game provides sufficient resources for F2P progression even with suboptimal starts. Focus on securing at least one top-tier DPS character (Reno, Kaiju No. 8, or Gen Narumi) within your time budget. Remember that team synergy and strategic play often matter more than having perfect starting characters, especially since the game regularly provides opportunities to acquire new characters through events and accumulated resources.
