Kazuha Toyama

Kazuha Toyama (Kristen Thomas in the english dub of the anime) is a childhood friend of Heiji Hattori. She has had a crush on him for some time, though he doesn't know. Her father is a police detective, as is his.

She met Ran Mouri, and initially they did not get along at all, due to a misunderstanding, (she thought the 'Kudo' he kept going on about was a girl he had met, and seeing them, assumed she was 'Kudo', and was quite embarrased when corrected) but eventually they warmed up and became close friends, able to connect over their shared experiences and frustrations over their similar 'not-boyfriends'.

Her name comes from fictional police detective Kagetomo Toyama and an assistant of the mangaka, Kazuha.
