Way of the Assassin Part 3 help

[S E 7 E N]

Hey guys, I'm playing the VN version because I live there now. I'm using the English patch and there's no icon for when I'm doing the quests with the hongmoon kid. I guessed the first 2 parts, but I couldn't figure out the third.

 

In the old BNS, you had to press 1 and then 1 again to sweep. But in the new BNS update, there's only shadow drain for 1. I tried that and it doesn't seem to work. I tried every other combination I could think of, but nothing is working. Anyone can shed light on what I'm supposed to press for this?

 

Thanks!
