Stop Rerolling if You Pull Sagan

For rerolling in Kaiju No. 8, it's okay to stop as soon as you pull Sagan. Sagan is a Defender who is easy to use from the early game, and can deal damage with her counter while protecting allies. She is a character you'll want to aim for due to being a limited-time character and her versatility.

Sagan's weapon, "SH-Iuggnil," is also limited. Currently, the 5-Star Shield can only be obtained from the Sagan Gacha, so aim to pull it. Try rerolling or use the Dimensional Crystals you collect after starting the game.
SH-Iuggnil (5-Star Shield) StatsCan Also Stop Rerolling if You Pull 5★ Reno

You can also stop rerolling when you get 5★ Reno. Reno is a top-tier Attacker who can inflict Freeze and recover SP. He is not available from (Standard) THE GAME Gacha, so opportunities to obtain him are limited.

Pulling AR-Boreas is Optional
Boreas also has a 1% drop rate, but you should aim for Reno. Weapons can be obtained elsewhere and can be substituted, so prioritize pulling characters.
Stop Rerolling if You Pull No. 8 & Narumi
If you obtain both Kaiju No. 8 and Gen Narumi, you can stop rerolling. While rerolling for standard characters is usually unnecessary, getting these two top-tier units together is a good stopping point.
Use the 5-Star Exchange After Rerolling

After using your initial Gacha Tickets and finishing rerolls, use the 5-Star selection exchange. Pick a character for a role you are missing in your roster.
