He takes the bottle of water, giving himself a moment to make sure he's got a good grip on it. "... I don't. I lived on the street, I ate whatever wasn't rotten. I'm still here." None of it killed him, so he's fine.

Ken takes a drink from the bottle, staring straight ahead.

"... Why?" His voice is scratchy, and he's not sure who or what the question is towards. Why couldn't he kill Aragaki? Why did Sakaki show up? Why did he get shielded? Why is he here?

Or why did all of this start in the first place?

He doesn't know. He takes another drink from the bottle, trying to focus on anything but his own thoughts.
