Dean Alder, the head of the Alder Academy, wanted to fight crime and instruct the young. Thanks to the Mystic Garment, a magic robe he wears, he can walk into and out of mirrors and gain powers. When he walks through a mirror, he becomes an intangible and invisible shadow, and he uses these power to fight evildoers. While a shadow, he can't hold anything, but he can while he is solid and normal.
