Yea... this is the only guy that entered the Ark as a useless extra ink and somehow has metamorphosised into an unbelievable exorcist somewhere in the midst of all the chaos.
So, what kind of ending do you want/prefer for this guy?
Ps: we're going to assume that the other exorcist will be out cold for the rest of the year so either chaoji saves himself or he dies. That's it. No, Allen, Lavi, Linali or a General gonna saves him, not even Timcampy =p
