and the stream on 2:37 is so easy if you know the patterns you can just hit it at the right beat(its just a normal streams/rolls that is very easy for veterans)
My theory on how Nikku can copy voices: Nikku cant talk properly. So she has to use other voices from people. Since she is this voiceless entity she can copy voices from other people (I’m too lazy to write a thing that looks like a whole script lol)
