(I'm using two, that's ok right?)
Miran Kanraku (Class 3-B, No. 7)
Hero Name: Inari
Quirk: Mirage. Through playing on a wind instrument with her quirk active, then when a ball of light appears yelling mirage, she emits a kind of aura that affects the area around the ball of light. Different wind instruments affect how she can use her quirk. For example, a flute can help when creating an illusion in a zone where she wants to stay there, but playing an ocarina and holding it with her creates a moving field as long as she has the ocarina with her. She abuses the heck out of her hair being naturally white, allowing her to dye it all sorts of wacky colours without the need for bleach. Currently its a rainbow. Her eyes are vaguely fox like and amber.
Soraphimu Kenraku (Class 3-A, No. 8)
Hero Name: Loki
Quirk: Walking Nightmare. Considered a villainous quirk. Transferred in from General Course in his 2nd year. Through prolonged eye contact, he can turn into the person someone fears the most. E.g: Prolonged eye contact with All Might may have him appear as All for One. Of course it's similar to Monoma, since he doesn't get automatic mastery with a quirk. Constantly wears mirrored shades to avoid that. His hair is naturally white, and he had red eyes, though his left eye is pure red and has a streak the same colour running down from his left eye to his chin.
(they are siblings)

Miran: What the hell.
Soraphimu: *He's staring at the scene, his eyes widened behind his mirrored shades*
