Honestly I forget about Kurosaki - he's the #2 for a reason I suppose, but is it possible he has the solution? Or more likely, he's here to light a fire under Endou's ass. Which is the last thing he needs, imo.
What I'm most interested in right now, honestly, is what Kazuya's up to. It feels weird that there hasn't been a single moment involving him ever since they left with the money.
Yes Minkulus I'm guessing Fukumoto is keeping that for the time they'll get face to face. I'm convinced they will get caught and there will be a new confrontation with Kazuya and his father.
