A child had been abandoned by her birth mother before the events of the game. The two are briefly reunited, though it is shown the mother only has selfish reasons for doing so. She renounces her daughter again following this.
There is a character in a few substories who is the embodiment of these cliches, being depicted as a promiscuous character who attempts to sexually assault the unwilling protagonist. Made even harsher by the original PS3 English translation with the protagonist making especially disparaging comments towards them. This character and all content involving them were removed from the remaster.
Not explored in a detailed fashion and barely addressed but several characters keep tabs and follow around other characters without their knowledge (ie: The Man in Black stalking Kiryu)
Kiryu is stabbed by an antagonist at the end of the game. He survives. There is another scene where an antagonist stabs someone through the hand with silverware.
