Let me start off by saying that I totally loved this book! I at first had my doubts because of the cover, and the synopsis, but I guess it's true what they say, "Don't judge a book by it's cover" because this one was a good one! 
 I'm totally in love with Japan and all things Japanese, so I was ecstatic to start reading this book because of the topic of a foreigner living over there and learning the language, too. It was really nice being able to read and learn about the several Japanese lingo that was used throughout the book. Plus not to mention it was a realistic portrayal of how Japan was, I could tell the author did her research well because it read more like she actually visited and got decent notes, and it wasn't all made up like other books I've tried to read. It interested me because the basis and plot of this story read more like an anime (sorta like Kamisama Hajimemashita) and I wanted to see how it was going to read when it was written instead of being watched as an anime and I can say that it was a really well written story. It would even be cool to see a movie/anime adaptation of this trilogy someday. 
 Now, I loved the mythology that was mentioned, especially about the Kamis and all the culture and customs of Japan that was used and properly described. I found myself immersed in the story and the culture and I liked that about the author. It also helped that each character was written nicely and I could easily pick out what the role of each person was- the MC, the tsundere Tomohiro, the kinda airhead best friend Yuki, the best guy friend Tanaki, the evil guys: Ikarashi and the Yakuza members. But either way, I loved reading this book. 
 The romance between Katie and Tomohiro was sweet and funny and just romantic to read about. Being as how they were in Japan and their culture and customs are different than here in the US, whenever they so much as hinted that they liked each other or other innuendos or when they kissed, they were super embarassed and it was adorable to see them be all akward about it but obvious about how much they like the other person. It was a huge thing when they started to call each other by their first names (view spoiler)[a very important Japanese custom and if you don't know about it, look it up! (hide spoiler)] and all the times he was funny and sweet towards her. Sure, it wasn't the typical romance from most YA books, but it was special because of that. The whole deal with his powers and Katie affecting the ink was very important, even to their relationship. Fights with drawings, ink, kidnapped by the Yakuza, and other things make this book action-packed and also hilarious. I found myself not able to put it down, and now I'm anxiously waiting to read the next book in the series.
