Delta is stoic and can be standoffish at times, and is somewhat cold to others. With friends she is more casual, but she isn't tolerating people getting too close to her. She also hates being treated like a child based on appearance alone.

Her tied pink hair has strands of blue, her eyes are blue. She has a horn on each side of her head: black and pink on the right, black and blue on the left. Her tail is black and her tip is a mechanical gripper arm, wielding her greatsword. Cyberpunk style.
