heads up, getting my Wisdom teeth out tomorrow, so I'm going to be unavailable for a bit. Not sure how long, but for sure tomorrow.
edit: Also, reason why Itsuki isnt saying much is because it doesn't seem terribly important to him. Ghouls attack ghouls every day, especially in the 24th ward, so he doesn't see the point in giving specifics, especially when he has something more subjectively important to deal with. Just a bit of a look into his motives for acting as he does.
