Akane Mukai is the ultimate mangaka, she is the creator of three manga series that have been a hit around the world. Her stories and drawings reflect her personality, bubbly, dreamy and always ready to make people around her smile. She is absolutely addicted to Japanese culture, maybe even a little too much, she uses honorifics, Japanese words in all her conversations and doesn't hesitate to praise Japan at every opportunity she gets.

Even if Akane speaks Japanese, I don't consder it necessary for you to speak Japanese, just look up the prononciation. She has a very high voice, one of my biggest inspiration for her character is Sarah (Suki) from HuniePop2 so I'd imagine a similar voice for her.
