... it's just me, Ookurikara, and Tsurumaru. We're all.... friends. [dumb tsun] They're morons, that wasn't a lie, but they would never kill an innocent person without an extremely good reason. 'They'll become corrupted if we let them live' or 'we all need to die in order to get out of here' reasons.

So you don't have to worry about them.
