YMMV / Da Capo 4

• Awesome Music: Sakura Biyori, the game's final ending theme... which sadly plays a single time, and the game only uses the first verse of it.
• Squick: Shiina is Ichito's daughter from another reality. While the game itself tries to downplay it by asserting that since the two worlds are subtly different, it's not technically the same Ichito and so it's not true Parental Incest, it can still make their romance come off as more than a little bit icky.
