I dont think so though because when buffs are removed, its usually stuff like root of warrior or flower guard, so i dont think it should affect kushina or anyone who scales

The only thing that reset scaling is death and then revived

I want to 2nd this being a good question. First, I've seen that once immunity is removed, scaling ninjas can catch certain debuff effects like every else.

For example, using fireman immobile + imprison on kushina opens her up to dream status, where she can sleep for two rounds. C*so happen to 6pths. What I haven't been able to confirm is if she c*so be enfeebled in this imprisoned/immobile/nonimmunity state.

The new enfeeble state from *y jutsu naruto also temporarily remove the stacks

Last I recall all scaling abilities and de-scaling abilities (such as like gamariki or bee when you hit him and lose 12% def/res) cannot be removed into you die and get revived
Example edo madara can only remove buffs like iruka,bee,non sb hashirama and he'll remove all barriers no matter what

but scaling from kushina,minato ,shisui sus all stay around into death
but now on the topic of enfeeble/weaken that debuff cant go threw immunity but if it does, what it does is it lowers the enemy attack and ninjutsu by 80% and removes attack and nin scaling for that round so let say ....a ronin naruto scaled 60% attack...once he get infeeble he'll get his attack and nin lowered by 80% and...that 60% scaling he did will disappear as long as he has infeeble on him.
