The Pillar of Flame, Rengoku, and the Third Upper Demonic Moon, Akaza, were having a fierce fight. Rengoku was very injured and tired, but because of his spirit and unbreakable will he continued fighting. But Akaza had the advantage.

From afar you saw how Akaza's arm was about to pierce Rengoku's abdomen, you knew that if Akaza gave that blow, Rengoku would die. And Tanjiro wouldn't arrive in time to save Rengoku, but you would.

What will you do?
