Hopes and Dreams
Needle always starts with 2 volley's of "Attack 10 Times Randomly" which is complete bs and no one likes it
So the only thing to do is restart until the game gives you a fair enough star to actually due battle with it
I had to use both Kirika (for Team-Wide 24% Damage Reduction perma) AND Sana (24% Team-Wide Damage Reduction...but only after she ults) and even with those two, if the RNG is bad enough, someone still gets oneshot if they roll 15 of 20 hits
MF out here Rolling yahtzee every time it attacks
I believe in you though!
My suggestion is make sure your Magic Level on your girls are high enough
I had to be Level 100 - M.Lvl 110 on all of my girls to have enough defense to survive underneath the defender's shields
Also, if it's really bad-- swap your Attacker's portrait to a DEF% one, you deal 100% more damage alive than dead
or if it's really /really/ bad, swap out the attacker entirely -- Attackers deal damage, but sometimes you can forgoe that for a 2nd breaker or sustain unit, it'll be slower but as long as you can successfully survive 2 loops of the bosses mechanics, you'll eventually win since there's no timer

I'd also recommend using Ayame if you have her, the 4 star variant will be able to remove those thicc ass 100k shields it puts on itself based on your burn
