These would be my picks, it would be glorious.
She is perfect for the line in my opinion, referencing magical girls like Mami Tomoe. There even is a pretty known fan concept that is ideal.
She could be the smart one of the team, planning their strategies.
Star Guardian veteran. She got heavily injured on a mission and the first star was just able to save her by giving her a new magical artificial body. Kuudere, she seems emotionless. Feels lonely, because she can't go to school like the others because of her body.
Loves the freedom and to fly with her familiar Valor. She shares this with Ezreal, which she meets and he teaches her alot about teamwork, since she tends to be a lone wolf.
Himedere, wants to be treated like a princess.
The daredevil of the team. Always wants to get in the fight head first.
