Describe Mika Kanai here Ex-wife of Koichi Yamadera, who is also a seiyuu. Mika Kanai is one of the go-to seiyuus when it comes to characters that hasn't even reached puberty or at least just plain cheery. Not to say that's her only role, she occasionally plays against her type, whether it's about shyness or completely emotionless characters. She also has a singing career.
