I’m trying to figure out what anime my friend is watching.

My friend recently started watching anime and she wouldn’t tell me what she was watching, so we have been playing a guessing game to figure out what anime. The answers I’ve got are :

It’s on Netflix

it’s set in the future

its made in 2009

the main characters have yellow (or blonde) and blue hair

it is not: assassination classroom, Jujutsu Kaisen, any romance anime or isekai, saiki k, My Hero Academia

If anyone has some questions I could ask or knows what anime it is please answer the post.
