I'm sorry about I made a mistake to fail at the first time, that is for kushina attack to bring a combo with the immobile debuff but that time I did not use her mystery to break the immunity, so I failed that way. maybe I can wait for kushina's cool down but I'm making a video so I just retreat to do it once more to show you how to beat this

I did not find how to upload video directly, so I upload this to youtube instead. this is the address:
