[sharing] Yui Makino
Also a seiyuu mostly known as the voice for Sakura from Tsubasa Reservoir Chronicle, Yui Makino also contributed many songs for the series too. She also was credited for the songs made for ARIA. She has this childlike voice that didn't go too squeaky, and I really like it, which is strange for me. I tend to avoid singing seiyuu because I don't like chipmunk-y/forced cuteness voice, but Yui is an exception.
Check out Spirale, Tanpopo Suisha, Euphoria, Modokashii Sekai no Ue de, and also the acoustic version for Yokogao. Either album is a good start to try out.
