...and other characters.
This session takes place after [Main Story 022]. On my way to unlock Chihaya's the Fortune Teller, I checked the Side Quests screen and found I can unlock a Synergy event with a girl named Hiyori. SHe loves cats, and makes money to help them. Later in this session, I increase my Synergy level with Merope. I think changing the term from Social Links/Cofidant to Synergy somehow fits this game a lot!!
Here are some screenshots from this video:
