Gandr from MC is technically 500% stun, similar to Scathach NP, making it rarely fail (and it can fail if enemies resistance are high, like some CQ enemies).

If she resist that and "Reduce no-move resistance 50%" exists among KP its simply that you're dealing with 500%++ that reducing the number by 50% allowing Gandr to have chance stun her.

Given all available bosses, it still not fall into immunity unless the fight stated so with debuffs immunity icon. If there's no immunity icon, the explanation is simply the resistance are goes higher than 100% (up to 5000%, highest number they could pull IIRC).
