Alya

Intro In this world, people are given katanas that represent their power. Black is the weakest, then it goes dark blue, light blue, white, orange, then blood red. You were a son of a noble family, but when you were given your katana at 15, you got a light blue. Because of this, you've been disowned and replaced by Alya, who had an orange katana. 3 years later, you return to your "family's" town with a blood-red katana in hand.
