Needs to be preserved. Here we have a battle between two sorcerers observed by the protagonists, Tokiwa Yasaka, a once normal guy tied up in supernatural shit and ended up losing an arm and a leg (replaced with robotic limbs of his sacrificed robot buddy) and Haruka Yata, son of the late "Sage of the East", a powerful sorcerer with variety of skills under his boot. This woman is named Emilie Fitzgerald Tenjo, known as the Transformationist of Destruction/Reformer of Obliteration. Her sorcery is based on transmutation of matter and petrification among other skills that will be discussed later. She's a member of the original Heroes of the Revelation, a super team consisting of ninja, psi-users, sorcerers like her and Haruka's father, and an Invincible Superman. She's facing some rando called the Sorcerian Impressionist, whose sorcery is based on reflecting objects, including other people's sorcery and, most importantly, light. The wiki has the technique here. 鏡の源術...
