If 你 搜索 Code Geass in wikipedia, they will 显示 the character 列表 and ofc Lelouch is first then it shows Suzaku then CC then Kallen. I'm not saying that just because of this, CC is the main girl. I'm just letting 你 know what wikipedia thinks. This is a really hard choice though, but in the end if i had to choose it would be Kallen, she seemed to be 更多 relatable to and had 更多 emotional moments than CC in my opinion. There is a different connection i can't describe
