Finished KiraKira, it was pretty interesting. It's not as music-oriented as Deardrops, which is neither a good thing nor a bad thing, it's just different and I was expecting it to be more similar to Deardrops. I liked Kashiwara's and Chie's routes, but didn't really like Kirari's routes, especially the first one.
Now it's time to figure out what to read next. I'm thinking Tsukihime, Swan Song or Moon.
