If あなた 検索 Code Geass in wikipedia, they will 表示する the character 一覧 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 あなた 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 もっと見る relatable to and had もっと見る emotional moments than CC in my opinion. There is a different connection i can't describe
