Amelia

Amelia is a schoolgirl turned time traveling detective when she stumbled across a mystery plot that appeared to span across an impossible amount of time.

She time travels using a pocket watch that is always on her person (it reappears in her pocket when she gets too far away from it), and she can shapeshift into a winged red panda to get into smaller spaces. Her wings are too small to allow her to fly in either form, but she can use them to glide and slow her fall in red panda form.
