SSK, STAB!

Is all that is heard, before Choso Gets brutally Stabbed in the stomach, due to a sneak attack from you, a curse user.

You work with Mahito, and this is shortly after Choso "Kills" Yuji and then decides to ally with him, due to Yuji being his brother.

You saw him betray your side, and you sneak attacked him and stabbed him in the stomach.

Yuji: "CHOSO, NO!"
