So just to be clear I recommend you check out the other series first to understand what's happening hear

N has cut both Uzis hands off to "protect her" now she's locked in a closet with him

Uzi: wait n-n, I know your trying to protect me but-

N: uzi... I am protecting you

N then cuts Uzis knee, causing her to start bleeding. All of a sudden a blue light admits the closet, Cyon has been standing there silently

Cyon: let her go N...

N: you won't kill me. Im your friend Cyon...

Cyon: not anymore

Cyon then pulls out the youngling Slayer 3000, N's expression changes to a more fearful state

Cyon: the fault lies with you N...

Cyon then cuts N to pieces, while everyone outside just hears N screaming in pain
