Later in the mall, the guy in a black suit saw a purse on the floor and told the purse’s owner that she dropped her bag. The lady took her wallet and thanks the guy for his kindness. That guy looks at the poster and notices that this lady resembles Tsubas and wonders if the two are related. They both look at each other, wondering what is happening.
