I just started reading this, so concerning a VA for Elsee:

While I think Aki Toyosaki would be a good fit, Ayako Kawasumi would be a horrible one in my opinion. You have to take "age" into account. Nodame is the right kind of character, but she fits because she's in her twenties. Elsee looks like she's 14, but acts like she's 9. When I think, "A fire truck! ♥" in Nodame's voice, it doesn't fit Elsee's character image. Kana Hanazawa would be much better. Elsee is very much like combination between Yūka Midarezaki (Kyouran Kazoku Nikki), Kagome Ikaruga (Asu no Yoichi) and Kusano (Sekirei).

Ayako Kawasumi would fit the more dignified characters, like the karate girl or Hakua.
