oh I haven't posted in this one yet well since this is for R1 only I guess Rolo isn't an option
so my favorites for R1 are
CC- she is Kuudere and there would be no CG without her
Kallen- I like badass women in mecha anime
Suzaku- cause idk umm yeah I just like him
Lelouch- I liked his character development although I hated some of the things he said and/or tried to do to Rolo.
Milly- I like her crazy school festival ideas plus she has an awesome personality
Corns- another strong woman and one of my personal favorites from the royal family
Euphie- kind hearted princess that wants to make a place where Japanese and Britannians can live together peacefully
Rivalz- funny, sweet guy, and like Tamaki another comedy relief character of the show
Viletta- I've always liked her don't know why especially after her memories disappeared for a bit.
Jeremiah- 200% loyalty
Tamaki- the comedy relief of the show
Sayoko- cause Ninja maids are ftw
Lloyd- everyones favorite scientist
*insert rest of R1's cast here that are NOT Shirley and Nina*
