Ember, member of class 1A, her quirk Demon dog. A quirk with inhuman strength and the possibility do whatever the owner instructs to do. When not under control she's just a quirk-less human with purple skin and demon horns. With a second form, cat mixed with demon she can shrink up into a mute animal, and stay close by her owners side, normally chilling on their shoulders. The bond can be made by the hand with the marking on touching someone who she looks up to, she can touch others with her hand and not become attached to them, however because it's not hard to impress her she wears a glove that will stop the contact.
