Kawashima, Ami of Toradora! is one of Eri's favorite characters that she has voiced.
Yui of Angel Beats!
This season Eri is voicing Liliana Krancar in Campione!
Ms. Kitamura actually like she herself is an otaku. She even is known to make her own manga. I wish I could find it for you but I don't think they are on the interwebs. Ms. Kitamura just recently released her solo album, Re;story. I actually have the album and I recommend it to anyone who likes some of the songs that she has done for her recent animes like C³, PapaKiKi, and Mayo Chiki!. Eri-chan also like to seem some rock songs on that album and also has a band called ARTERY VEIN who she sings with Imai Asami (Makise Kurisu).
Here is a music video for her song Re;story off her new album of the same name. Enjoy!
