Whatever is the matter with the Marshal, Kaji won't be able to solve it on his own, so he will retreat. Even the people who claimed to have the answers don't seem to have anything helpful, and if something goes wrong, this entire thing might turn into 'hero' on 'hero.' So, okay. He'll look for the one person he feels responsible for, and try to get the both of them out of here, find another cure.

Kaji won't find Ib, but he'll come across another far too sick person, instead. However things fall out with Shun and Sparks, the info broker is going to find himself dragged into a different fight.
