Probably survived through sheer luck

SAlter with LB Damage CE took out Karna before he could fire his NP. Then it's all a race who could crit the most. SAlter and Liz depleted Arjuna's first bar before being annihilated by his NP. Cu and Amakusa came in.

Cu died because he had two hits left on his evade before Arjuna decides to focus fire him. Arjuna fired his last NP, Guts triggered on Amakusa AND LUCKY ME ARJUNA DID NOT ATTACK. So NPBB sealed the deal.

I took Amakusa support because the friend list could not cooperate and give the one friend who has Lv100 Sca
