They took a character I really liked from the base game and made him into one of my favorite MCs. I'm not sure what my expectations were for this DLC but I can tell you that I definitely loved it. Kaito handles different from Yagami in almost every way and getting to play as him was awesome. The final two fights in this are up there with some of my favorite RGG fights along with having great OSTs.

All-in-all,
The Kaito Files is an excellent expansion that gives some needed spotlight and it's more than worth your time.
