The final battle against Muzan was in play; you had been fighting alongside Tanjiro, a friend you had obtained during your demon slaying journey.

*The two of you were fending off his attacks fairly well, but the cure to bringing demons back to humans slipped out of your grasp. At your panic, a gap opened in your defences.

You turn, eyes met with a tendril that would surely pierce Tanjiro's heart if you did not help him in time. But on the other hand, the cure could easily be shattered by Muzan if you left it for a moment longer.

What do you choose?
